Re: Tomcat 9.0.36 - JDK 13/14

[Kiran Badi]

we fixed the issue Mark.

Actually tomcat was running on JDK 1.8 and applications were built using
JDK 13/14.So when they were deployed to tomcat running with 1.8, they were
giving 404.

Now plan is to explore and upgrade tomcat to at least jdk 13.

It would have been nice really to have at least some error saying major.minor
version exception or something like that in some logs somewhere which java
often throws in these cases.

Any ways we are good to go now. Thanks for your reply.

Tomcat 9.0.36 - JDK 13/14

[Kiran Badi]

Hi All,

I wanted to check if tomcat 9.0.36 supports open jdk 13/14.

I created a simple spring boot war file and compiled/built it with openjdk
13/14. After running maven install , I deployed the war file from the
target directory to tomcat webapps using tomcat manager. It did not work
and gave me 404 messages with both 13/14. No error or any exception
anywhere in logs.Catalina log just says a war file is deployed.

Then i compiled the same spring boot app with jdk 8 and deployed it with
tomcat and it works fine. I am able to call my endpoints with no issues.

I am having a hard time deploying angular/spring boot and building war file
and deploying it on tomcat 9.0x with openjdk 13. So I thought this might be
a good place to start with.

I used the below pom file.

[Kiran Badi]

Thanks Jakel for the link and thanks Shawn for reply and some insights.

I did scan some of my application logs and can see some kind of XSS attacks
originating from china/Russia .Most of them were targeted to the database.
Tried to reproduce many of them , they don't yield anything.

I have not yet figured as how they have gained entry to the system.I will
spend some time this weekend to patch the things up and see if I can
investigate this further.

Re: Amazon EC2 Tomcat 7.0.85 not starting up due to some memory issue .Please mask if

[Kiran Badi]

Yes tomcat is not starting up. I am also suspecting that EC2 instance was
probably compromised. Not sure as how but I see some rogue programs were
running under tomcat user. I use putty with private keys to login and those
keys are not in public view for sure.

These program were talking to some servers based out of China,Russia and
Germany with tcp,http and stratrum-tcp protocol with jsonp as data exchange
formt. I am not sure as how they got access to my ec2 instance and got
themselves installed.

I did some initial analysis on this one and have put those files in my g
drive which I have made public. I suspect either they have used tomcat to
gain access or they might have used yum updates for getting access to ec2
instance.


cronjobs.txt contains information that some programs were running with
tomcat user id.

hs_err_pid23773.log contains pid  details for tomcat event.

jwzckuz.cf  is probably some config file installed by hacker.

rciwd - was actual program which was consuming too much of swap and cpu and
was running as cron job. Not sure as what this is.

script.txt is actual script I extracted from one of the http request by
capturing traffic via wireshark.

files with names 0515 are tcpdump capture on the server taken while
unauthorised programs were running.

172-xx-68-244  is my ec2 instance and 98.122.xx.xx is my ip in the trace.

https://drive.google.com/drive/folders/1K5gfXTEvmuoIynCYtlwmf7DknyGkvhMI?usp=sharing

appreciate if someone from tomcat team take a look at all the files I have
attached in the drive.

Please let me know if more information is needed.

Amazon EC2 Tomcat 7.0.85 not starting up due to some memory issue

[Kiran Badi]

Hi All,

For some reason my application hosted on ec2 is just not starting up. I
know I never had any memory issues in last 1 year or so.

I see below trace in catalina.out file. I am not sure if I need to add swap
space or file permission is an issue here. Something changed in ec2 that is
causing this error.I think they auto updated the tomcat version as well
from 7.0.82 to 7.0.85.

I seriously need some suggestions. I also need some suggestion as how to
prevent bots from trying to access manager app.

Re: Tomcat 7.082 not starting in EC2 after doing yum update

[Kiran Badi]

Ok this is resolved. It was permission issue. now tomcat runs under its own
user id and for some reason I missed to read tomcat.conf file.

Now it works however server start up is now very slow.

INFO: Server startup in 352544 ms

something which was very fast in earlier version 7.081  and 7.050

Let me check logs tomorrow for finer details.

Thanking you

Tomcat 7.082 not starting in EC2 after doing yum update

[Kiran Badi]

Hi,

Couple of hours(3 hrs) back I did yum update to install 7.0.82 version to
install latest security patch.

Yum update went well. Then tried to install ROOT war, after stopping and un
deploying existing ROOT.war. Deployment failed saying that ROOT folder
already exists. So deleted ROOT folder and ROOT.war from the web apps
folder. After this step, tomcat 7 seems to be not starting for some reason
and neither its writing to logs anything.

 I think I messed something very badly.

How do I figure this out. Do I need to do clean install again via wget ?

I hate to say that my linux skills are very rusty. so appreciate some help.

[root]# sudo service tomcat7 start
[root]#  [  OK  ]
[root]# sudo service tomcat7 status
[root]# s not running[WARNING]

whenever I try to restart , the only place it writes is tomcat7-initd.log

/usr/sbin/tomcat7: line 40: /usr/share/tomcat7/logs/catalina.out:

Re: Context Dependency Injection with Tomcat 7.0 x / 8.0 x

[Kiran Badi]

Thanks Mark,Christoper, Andreas and Chris for reply. Please accept
apologies for delayed response.

Tomee is an option but I need to see if client is ok with it. They are very
much in Tomcat and has most application deployed with Tomcat.

Chris,I would be happy to go with Spring, however the client I have has few
legacy projects and I need  to see if I can suggest them spring.

Weld and openbeans seems to be good option I can explore.Thanks

Context Dependency Injection with Tomcat 7.0 x / 8.0 x

[Kiran Badi]

Hi All,

I wanted to check if their is a way to do CDI with Tomcat for 7x and 8x
version as per JEE spec ?

I have a project for which I wanted to use CDI the way spring does it.

Appreciate if someone can suggest something.

Thanks Mark. Those links were very helpful and saved a lot of my time. I
had good learning :)

For few of the character which I was aware, I think I can go via C URL tag.
But I have see as what other special characters I might have. Its coming
from third party and I do not control it and I am using those as parameter
for the link.

request.getParameter and special characters - Apache Tomcat/7.0.57 on win 7

[Kiran Badi]

Hi ,

I have this link in jsp which has below tags,

<%@page contentType="text/html" pageEncoding="UTF-8"%>

 Testing

and then my servlet looks like below,

/*
 * To change this license header, choose License Headers in Project
Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */
package controller;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 *
 * @author Kiran
 */
@WebServlet(name = "TestServlet", urlPatterns = {"/TestServlet"})
public class TestServlet extends HttpServlet {

/**
 * Processes requests for both HTTP GET and
POST
 * methods.
 *
 * @param request servlet request
 * @param response servlet response
 * @throws ServletException if a servlet-specific error occurs
 * @throws IOException if an I/O error occurs
 */
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
/* TODO output your page here. You may use following sample
code. */
String param = request.getParameter("teststring");
String param1 = new
String(request.getParameter("teststring").getBytes("UTF-8"));
out.println("");
out.println("");
out.println("");
out.println("Servlet TestServlet");
out.println("");
out.println("");
out.println("Servlet TestServlet at " +
request.getContextPath() + "");
out.println("Servlet TestServlet at " + param + "");
out.println("Servlet TestServlet at " + param1 + "");
out.println("");
out.println("");
}
}

// 
/**

 *
 * @param request servlet request
 * @param response servlet response
 * @throws ServletException if a servlet-specific error occurs
 * @throws IOException if an I/O error occurs
 */
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
processRequest(request, response);
}

/**
 * Handles the HTTP POST method.
 *
 * @param request servlet request
 * @param response servlet response

 * @throws IOException if an I/O error occurs
 */
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
processRequest(request, response);
}

   }

and getParameter for some reason seems to truncating the value after &

Servlet TestServlet at testingServlet TestServlet at testing

I really need to understand as what characters are accepted and what
characters get truncated with getParameter.

I am building few links on the fly which might have space,backslashes,
comma and & characters in it.So wanted to understand should I encode it via
js or container can take care of those for me.

container connector setting has URIEncoding="UTF-8" settings.

Thanking you

Re: Tuckey Rewrite URL and infinite loop exception trace for Tomcat 7.0.57

I resolved it.My bad, to and from rule were having same url mapping and I
feel thats the reason it filter was recursively called and finally
resulting into stackoverflow error.

Tuckey Rewrite URL and infinite loop exception trace for Tomcat 7.0.57

[Kiran Badi]

Hi,

I am having some issues with  Tuckey Rewrite URL/Tomcat 7.0.57 and for some
reasons I believe I am not getting it correct. It seems to me that I am
getting into infinite loop somewhere.Not sure why but conditions do match.


 Hello World! This is a link I am trying
to clean it.

Below is test servlet.


 protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
String[] params = request.getPathInfo().substring(1).split("/");
System.out.println(params[0]);
String testid = request.getParameter("testid");
RequestDispatcher rd =
request.getRequestDispatcher("/WEB-INF/views/Hello.jsp");
rd.include(request, response);
}
}



http://www.tuckey.org/res/dtds/urlrewrite4.0.dtd";>






The rule means that requests to /test/status/ will be
redirected to /rewrite-status
the url will be rewritten.

/test/status/
%{context-path}/rewrite-status


 Sample redirect
[0-9]
^/GetServlet(.*)$
/GetServlet/testid/%{parameter:testid}




The outbound-rule specifies that when response.encodeURL is
called (if you are using JSTL c:url)
the url /rewrite-status will be rewritten to /test/status/.

The above rule and this outbound-rule means that end users
should never see the
url /rewrite-status only /test/status/ both in thier location
bar and in hyperlinks
in your pages.

/rewrite-status
/test/status/

Re: File size >= 2GB not uploaded in application [Tomcat 7.0.54 Struts: 2.3.24 JAVA: openJDK 1.7.79]

[Kiran Badi]

Hi Chris,

Ok but I had bunch of similar issues with file upload when I had done with
struts 2 and plain J2ee. So thought worth checking.

Maybe JavaScript part might be culprit or  form data of JS might have some
limit on size.and file upload via JS is supported only in last couple of
years.Older browsers relied iframe for uploads.

Yes without all the info it's hard to tell anything for sure.

Re: File size >= 2GB not uploaded in application [Tomcat 7.0.54 Struts: 2.3.24 JAVA: openJDK 1.7.79]

[Kiran Badi]

Did you exclude your upload servlet from struts.xml ? By default struts
intercepts all multi part requests and this messes a lot specially when you
have hybrid framework when few modules are plain j2ee and few are struts 2
or Spring MVc in the same app.

Are you upload less than 2gb file ?

Re: Tomcat Session issue - Session not expiring on browser close event

[Kiran Badi]

Thanks Chris and David for reply. I did change the timeout values from 30
to 10.

I have some workflow kind of screens,but I do not store work flows fields
data in session. Session contains only attributes which are similar to ids.
All data is persisted in the mysql database and I get the data from the
database. I do have some performance issues with mysql,but that can wait
for sometime.

(I believe the default maximum is 10,000

I hope this should be for single instance of tomcat and If I use cluster,
this limit will not apply.

5K is my break even point for my app, So I think I can live with this
default. However it will be good to know if this limit can be changed
somehow.

Sorry for delayed response, was bit held up firefighting in office.

Re: Tomcat Session issue - Session not expiring on browser close event

[Kiran Badi]

Hi Chris,

Thanks Chris for reply.

Perhaps you should think about using a leaner session, and then
sessions living for longer than necessary won't be such a big problem

What do you mean by leaner session ? Storing less objects in session or
changing default timeout from 30 mins to something of less value ?


I think got probable answer to my issue, I had overlooked the JSP part, I
have JSP's and by default JSP creates session, and this was reason as why I
was seeing thousands of session in my app.

Is their a way to kill the session after certain period of inactive time
where user is not doing anything on the site or I need to adjust my timeout
value ?

Tomcat Session issue - Session not expiring on browser close event

[Kiran Badi]

Hi ,

I have few attributes saved in session they seems to living for close to 30
minutes which is session timeout in web xml.

I need to kill the session once the browser closes on the client side.

Is their a way to do it on server side rather than doing via some kind of
ajax handler.

Doing it via ajax means injecting that code in all my jsp's and have lot
many.

Thanking you
Kiran Badi

Re: doDelete Servlet

Yup I solved this , just not deleting anything, I am not just setting flag

doDelete Servlet

[Kiran Badi]

Hi ,

I have CRUD Multipart request and I have implemented it correctly works
fine at my local host.

I have upload upload pdf and tiff files, all this implemented via ajax call
using onchange handler on file input multiple tag.

The challenge I am having is that doDelete just deletes the file with the
request on server, but their is no protection.

How do I protect doDelete call from getting misused ?

Is their something in Tomcat I can use to protect doDelete vals from
getting misused ?

Re: Dynamically Create Subdomains - Tomcat 7x

[Kiran Badi]

Let me try again Chris, I have this site www.mysite.com  ready with some x
amount of features in it

Now I need to customize this site based on regions,states, and cities.I
will most likely go with cities.

So I need my main site to redirect to city1.mysite.com  etc based on
cookie value which I create on mysite.com(This is landing page)



what i need  is similar to as what  www.blogger.com or craiglist does.Ex
http://www.quikr.com/all-cities,https://geo.craigslist.org/iso/us

when we add a blog, it creates user.blogger.com and for another user, it
creates user1.blogger.com

I am looking something similar ?

Can this be done with just tomcat or I need to front end tomcat with apache
?

Is it required to spend extra money on DNS or creating different
folder/subdirectory for each region ?

I have a single war file, and I intent to do this isolation service
layer/DB layer.

Does this make sense ?

I know its high level generic ask,but I really need some direction. Maybe I
am again vague,but I hope examples will give some direction as what I am
looking for.

Hi Andre,

I need something like,

My main landing page  www.mysite.com

Subdomains I am looking for

myfeature1.mysite.com

Dynamically Create Subdomains - Tomcat 7x

[Kiran Badi]

Hi,

I need some help, I need to create subdomains dynamically, Is this possible
?

I have a site, www.mymainsite.com

on this main site, I drop the zipcode and city cookie and then I forward it
to front controller, and it's this front controller  which will point it to
city subdomain.

Can we create subdomains on the fly in tomcat ?

Tomcat 7.0.27 and Tomcat 7.0.50 - Valve - Dead thread and Crawlers

[Kiran Badi]

Hi

I wanted to check if this setting in Server.xml is still valid,





I edited by server xml and added these valves,but I adding tomcat refuses
to start up and I see for some reasons Tomcat is not able to find those
classes.

Do I need do download some jar files to make it work ?

I am looking for these valves just to make sure that I collect valid data
from crawlers.

and manage long running threads.

Re: Tomcat - OOM Perm gen

Hi Chris,

Here is link for Dump files,

https://drive.google.com/folderview?id=0BxOQjvXCnkSifjZEcEYzUTNTbUFoUWdrdmMyT18wdkZDS0hEOEgwRnl6RTBWN0V6UlA1YU0&usp=sharing

I tried using eclipse MAT Analyser and I see most of the threads on related
to tomcat web context loader. I still need to spend some time on that.

I think my apps still needs some cleanup.

After a day or 2 , it often dies a slow death with message,

Exception in thread "ajp-bio-17703-exec-11"
Exception: java.lang.OutOfMemoryError thrown from the
UncaughtExceptionHandler in thread "ajp-bio-17703-exec-11"

I am going to upload a new war today and see if it resolves the issue.

I will need some help with from this group in managing bots which are
spanning 100's of sessions in my case.I will initiate a new thread on that.

Sorry for delayed replies from my end.

Re: Tomcat - OOM Perm gen

[Kiran Badi]

Sorry for taking time to reply Chris.

Are you periodically hot-re-deploying your application in production?
If so, you may want to stop doing that, as it appears that you have a
ClassLoader-pinning leak in your application or some dependent library

I do not do hot deployment in production.But somehow I feel its leaking
memory.There are some threads which for some reasons remains hanging.
But I think I will focus on it later on. I do have copy of your
presentation.I will go through it and may be post couple of question if I
have.

You should be able to run a reasonable service in half a gig of heap
space. Just be aware that caching information in your application is
going to significantly increase the amount of heap space required by
your application in a steady-state.

Yup I am aware of this limitation. I know cache is often stored in local
heap and probably that's reason it consumes heap space.
Currently I am checking if ehcache or jcs meets my need. Ehcache for some
reasons fills my heap very fast.I tried storing some 100 json strings and
retrieving them.
My OOM's started once I integrated this library in my web inf /lib
folder.After I removed it, frequency of OOM has substantially
decreased.Probably I am not using it correctly somewhere.

Do you know what open source caching people frequently use for java web
apps ?

Fetching a lot of data isn't usually a big deal. Just make sure that
your "fetch size" is set to something reasonable. There are some JDBC
drivers (MySQL Connector/J in particular) that will load the entire
ResultSet into memory before allowing you to traverse it unless you
make arrangements to limit that memory usage.

But bringing-back thousands of records from a db isn't a problem --
unless you don't *have to* in which case you might want to optimize
your queries to avoid pulling data you don't actually need.

But too-many-records would be a performance problem, not a memory proble
m.

haha.Its fetch size which my autocomplete was missing...I am not sure how I
missed it but it was missing.
Thanks Mark.

Re: why is Tomcat 7 invoking WebSocket protocol?

[Kiran Badi]

Hi Mark,

Sorry to jumping in

But even I have seen this in few of my exception traces though I never use
websockets.Some where down the line when exception is thrown wsfilter shows
up in traces.I am guessing it should be some kind of exception filter so it
bubbles up for exception types irrespective of protocol.

Let me check my old stack traces and post few snippets of it,but they were
valid exception in my case just that I never had websockets in my app.

Re: Tomcat - OOM Perm gen

[Kiran Badi]

Hi Chris,

The number of users shouldn't impact your PermGen space. Perhaps only
once you get to that stage are you hitting enough of your features to
load classes into PermGen. (Or maybe you are using String.intern a
lot...)

I analysed some logs and I could see that users query features which makes
DB calls, so those calls do have 1000's of rows in it.But some calls also
fetch empty result set and some error out, partly because code for those
calls are broken( Some of those dao classes have hard coded DB parameter
which I am cleaning it out now). As far as I know I do not do any string
cancat, those calls are all simple list fetch calls to views.

I am trying to implement some caching using either ehcache or JCS but I
think it has to wait for some time, till I gain some understanding on how
these works.( I think I need to serialize lot of model classes for that
probably will require some code changes again).i  know I have lot of work
to do ,maybe I one at a time change :)


PermGen failures will effect the whole JVM. There is no way to protect
App B from App A unless they are in different JVMs.

I can understand this. so doing daily restart now to manage  issue till I
figure out some solution to it.

What makes you say that? It seems that you have more information than
you are giving us.

Its not hardened code so I think it still has some issues with it. Also
during development I can see similar errors on local dev box, If I do
deploy and redeploy at least 8 to 10 times, I start seeing those  perm gen
errors,its just that it references a new class file every time,maybe I can
share it with you all once I get it again.
Also it's I have written this code and I am not that fantastic coder yet,
but I will reach there short span :)


Usually, PermGen doesn't have to be enormous. What's your memory cap
with your hosting provider?

I have private tomcat 7x but I remember hosting provider mentioning that
512mb is final,but I will check with them again later this week.

Below is what I see in catalina logs when I do restart of tomcat,


Picked up _JAVA_OPTIONS: -Xms20m  -Xmx128m -XX:MinHeapFreeRatio=20
-XX:MaxHeapFreeRatio=40 -XX:NewSize=10m  -XX:MaxNewSize=10m
-XX:SurvivorRatio=6 -XX:TargetSurvivorRatio=80
 -XX:+CMSClassUnloadingEnabled -XX:+CMSClassUnloadingEnabled

I think was thinking CMSClassUnloadingEnabled should fix my perm gen
issues, but I think its not the case.



You either need more PermGen space, or you need to locate some kind of
leak in your application and fix it. IIRC, there are some RMI-related
leaks and Proxy-related leaks in PermGen depending upon your exact
circumstances.

It would be good to know what's in PermGen when it hits its limit.

What are your current heap settings, including PermGen? What JVM?

Try:
$ jmap -heap 

and

$ jmap -permstat 


I will try to get those dumps but I do not use any RMI or generate some
kind of proxies . Mine is simple app with lot of forms in it. Though there
are few calls which fetches lot of data from servers.Sometimes few
autocomplete calls fetch 1000's of records.I am trying to remove those
calls.

Below is my jvm details

Apache Tomcat/7.0.50 1.7.0_17-b02 Oracle Corporation Linux
2.6.32-531.29.2.lve1.3.11.1.el6.x86_64 amd64

Tomcat - OOM Perm gen

[Kiran Badi]

Hi All,

I have 2 web apps sitting on single tomcat instance, App A( Classic
JSP/Servlet/jstl/velocity App)  and App B (Struts2 based app).

Now I have added S2 to App A and trying to fix some bad code in it with
it.But after making this change I keep getting out of OOM issues once user
count reaches to 75 + and App A seems to be bringing App B down with it.
Below is trace I get in catalina out log. I think  I can increase memory
but it will not solve this and I have hard limit of memory with hosting
provider. Is their anything in tomcat that I need to enable which can give
me some mileage ? How do I fix this ?

Re: Tomcat 7.0.57 - Deployment Issue

[Kiran Badi]

Thanks *Jeffrey Janner *and *Mark Eggers*, I was able to deploy the app
successfully in its own virtual host. Actually I think apache httpd was
interfering somewhere and I raised the support ticket with my provider.I
think they made some changes to host file and it started working. I had
done same set up as given in the link by Charles.Now it works like a charm
and I also have manager interface to upload war files :)

Sometimes I get this error while using manager interface,

“Error invoking method check” when deploying a WAR on Tomcat
<http://stackoverflow.com/questions/1536364/error-invoking-method-check-when-deploying-a-war-on-tomcat>

But deployment happens quite successfully but it does not start the app.
Need to restart the server fix this.

Quick google search showed me that  its related to OOM. Is this related to
manager app or tomcat is starving of memory?

Re: Tomcat 7.0.57 - Deployment Issue

[Kiran Badi]

Thanks Hassan/Prabhu/Charles for reply.

I tried the options given in this link.

http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts

but for some reasons still its not working.I have pasted the server xml for
reference. I have unlimited website hosting plan with arvixe.com , but for
some reasons it's still not working.Not sure if these guys needs to add
something special to hosts file.

here is link for actual site -

homelyhotels.com - you will probably see cgi-bin folder.

Below server xml, I have added just a second host tag for webapp2. I am bit
hesitant to make changes wrt to webapp1(removing context tags etc due to
lack of time on my end along with lack of sufficient knowledge in case
something breaks,however I will eventually clean that as well).

Re: Tomcat 7.0.57 - Deployment Issue

[Kiran Badi]

for some reasons it's not going well. Its getting deployed as single app

www.mywebapp1.com\mywebapp2\ rather than 2 seperate sites.

mywebapp1 is deployed as root.war

and I uploaded the webapp2.war in webapps folder and edited server.xml with
below details,

 
  www.webapps2.com
  myhostid.myhost.myhostserver.com
  
   
   
   

I did not touch webapp1 app since its deployed as root.war and its working
fine..

One more thing, do need have one more connector tag as I see these error on
catalina logs

Re: Tomcat 7.0.57 - Deployment Issue

[Kiran Badi]

Thanks Hassan for reply.

Here is server.xml I am going to try in this weekend. I have added host
tags inside the engine element and mapped webapp1 and webapp2.

Do I need to rename both war files to ROOT.war and drop into the respective
folders or just drop the war file as is ? I have context xml inside
meta-inf for both apps.

Maybe I can experiment this in dev local box before propagating it to live
server.

Tomcat 7.0.57 - Deployment Issue

[Kiran Badi]

Hi All,

I need some help with my situation here.

I have private tomcat with hosting provider which allows me to deploy
unlimited domains/sites.

Now I have 1 web application deployed to that tomcat at the root folder.
Lets call this app as webapp1. I just rename webapp1.war to ROOT.war and
drop it in webapps folders. So it works and can accessed by

www.webapp1.com

Now I have another webapp2. which I need to deploy it to same tomcat and
access it as

www.webapp2.com

How do I do this ? Appreciate some direction on this please

- Kiran

Re: My problem: I cannot successfully get or set a session attribute from a JSP file.

[Kiran Badi]

I agree with Terence check if request is indeed getting fire. Add couple of
alerts to jquery call. You can also check if value is getting added to
session via tomcat manager admin interface , I remember there is option to
see session values /attributes over there.

Re: Struts 2 /Glassfish to Tomcat migration

[Kiran Badi]

Thanks Chris for replying.I did resolve the 404  issue,it's error on my
part. One of view jsp was in incorrect folder so it was throwing 404
error.Fixed it and now it works fine.

I do not recall as how I installed this tomcat probably I downloaded the
zip file and then integrated that installation with netbeans.


x86-64 do I need to download this file from apache tomcat site ? how do I
use this file ? edit the environment variables ?

Struts 2 /Glassfish to Tomcat migration

[Kiran Badi]

I am migration my glassfish struts 2 based application to Tomcat 7.055.

I am coming across 2 issues, first one is below exception while starting
Tomcat

java.lang.UnsatisfiedLinkError: C:\Apache Software
Foundation\apache-tomcat-7.0.55\bin\tcnative-1.dll: Can't load IA 64-bit
.dll on a AMD 64-bit platform

these are java information,

Using CATALINA_BASE:   "C:\Apache Software Foundation\apache-tomcat-7.0.55"
Using CATALINA_HOME:   "C:\Apache Software Foundation\apache-tomcat-7.0.55"
Using CATALINA_TMPDIR: "C:\Apache Software
Foundation\apache-tomcat-7.0.55\temp"
Using JRE_HOME:"C:\Program Files\Java\jdk1.7.0_13"


Though the server starts and I can access the home page,
but it seems like struts.xml file is getting ignored and i am getting 404
for all jsp which are under web-inf.

Is their any migration guide from glassfish 4x to Tomcat ?

I was thinking that copying struts.xml to config directory and setting
dispatcher servlet should be sufficient.I am missing anything here.

Re: Deploy application as Root

[Kiran Badi]

Hi Ognjen,

Thanks for information. Let me try this approach. I have another 3 weeks
for doing deployment for first piece of second app.

Probably I will start another fresh thread for few of my doubts.

Thanks and Appreciate your assistance.

Re: Deploy application as Root

[Kiran Badi]

Ok I fixed this issue. Moved the context tag to context.xml and deployed it
as ROOT. Works fine now.

However I have another application which I will be deploying in the same
tomcat.

This will be basically myapp2.war ,so how do I manage this deployment so
that whenever someones gives www.myapp2.com, it should open up ?

I assume we cannot have 2 root deployment in the same tomcat.

Re: Deploy application as Root

[Kiran Badi]

Ok I made the changes, and trying.

Andre, I tried your approach, it still same error.Making changes to server
xml now.

Pointing appBase to webapps.

Question I have is that if I upload war file via manager app, where does it
go ?

I can understand that ROOT goes to the ROOT folder if I delete the root
folder, how about myapp.war ?

Does it go to work folder ?

Konstantin, I have below version only difference is that localhost is on
windows and not working one is on linux.

Deploy application as Root

[Kiran Badi]

Hi,

I am trying to deploy application as ROOT.war in tomcat  7.50 provided by
hosting service provider, but for some reasons I get below message

FAIL - War file "ROOT.war" cannot be uploaded if context is defined in
server.xml


I have below in server xml,


Host name="Myapp.com" appBase="path  to public_html folder">
  www.myapp.com
  myuserid.myhostingprovider.com
  
  
  
   


However the ROOT.war gets deployed correctly in my local
machine.Appreciate some help here for fixing this issue.

Re: Tomcat-user versus StackOverflow

[Kiran Badi]

I think I prefer  to stay with Tomcat users list. Problem with SO is that
they close the questions without the second thought.Its becoming more of
kind of dictatorship. Too generic , close it and too easy, flame the poster
altitude.

Again I don't have any issues with SO and I did receive lot of assistance
from there and I still use it,but would not prefer apache list going SO way
till they provide the same flexibility as we get in apache list.

Re: Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext for tomcat 7.0.50

[Kiran Badi]

I had a missing jars in lib for this version of tomcat. Once added java
mail api jars, it started to work again.

Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext for tomcat 7.0.50

[Kiran Badi]

Hi All,

I have 3 tomcats installed in my machine, one is 7.0.27, 7.0.35 and 7.0.50

Now when I deploy my war file to 7.0.27/7.0.35 it works perfectly fine and
deployment goes through.

But on 7.0.50 it fails with below message,

FAIL - Application at context path /myapp could not be started

FAIL - Encountered exception org.apache.catalina.LifecycleException:
Failed to start component
[StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]]

In catalina logs I see below message,

I want to run it as service.I installed this by running service bat file
from cmd prompt.once installation was success full.I checked local
host:8080.over there I see version 7.0.2 .I cannot remove all tomcats since
it will large effort for me.but I know there nothing wrong with those.they
sit in different directories.I will paste the screen to marrow as and will
rechech once again.

Trying to install tomcat 7.0.35 but after installation it shows me as Apache Tomcat 7.0.2

[Kiran Badi]

Hi All,

>From this link,

http://tomcat.apache.org/download-70.cgi

 I downloaded the Tomcat 7.0.35 from core binary distribution.32-bit
Windows 
zip
 
(pgp
, 
md5
)

http://www.motorlogy.com/apache/tomcat/tomcat-7/v7.0.35/bin/apache-tomcat-7.0.35-windows-x86.zip

I wanted to install this as service in windows 32 bit vista home premium.I
installed it correctly and I can open and get into admin page.

However in admin page of tomact I see the version as
Apache Tomcat 7.0.2

Any ideas as why I am seeing 7.0.2 rather than 7.0.35 ? I need to install
7.0.35

[OT]- MYSQL + Tomcat + Apache + Java Hosting in India

[Kiran Badi]

Hi

Not sure if this list accepts these types of questions here,still asking 
shamelessly sorry for this.


If anyone knows some good web hosting provider in India, can they reply 
here or to me privately.


I checked with bigrock,rediff and some other known provider like sify 
and they said that they do not support java  or tomcat.


Thanks

Re: Where do I store Images in tomcat structure so that I can retrive it properly in all browsers

[Kiran Badi]

On 9/17/2012 10:20 PM, Christopher Schultz wrote:

If you instead implemented your own "aliases" feature using a servlet,
you could do it in a smarter way because you understand your own URL
space: you might always know that /images/X will translate directly
into /file/place/on/the/disk/X and you don't have to do a prefix
match. You could do something like this:

// configured once
Map dirMapping = ...;
String imageURIPrefix = "/images/";

// For each request:
String uri = request.getRequestURI();
String imageDirStr = uri.substring(0, uri.indexOf('/'));
File dir = dirMapping.get(imageDirStr);

Now you know where your file should be, and there wasn't any linear
lookup: it was all done using hashes.


Ah, I can implement it, if my understanding is correct, what you are 
suggesting here is that grab the incoming url, check if they are making 
a request to Images, if yes then point the url to the appropriate 
directory of images for serving.I can do this if it gives me good 
performance.


I was under impression that Tomcat checks for the alias only once during 
it start up phase and somehow maintains the list of it in memory and 
will do automatic match without scanning each alias.My bad.


Alias as per my understanding is the one of the places where Tomcat 
looks for resources to  serve for the requests.


   Probably not: the suggestion was to use, say, ${imagePrefix} in your
   context's aliases setup to simplify the re-location of your image root
   on disk.

I did not get this probably one of the reasons could be I am still 
struggling to come to speed.I might need some more days to think as what 
this means in terms of implementation.


   There's really only one rule for servlet programming:

   Don't use class-level data that changes.

   There are other considerations, of course, but a servlet is not a
   sacred beast. There's only one way to learn how to do it properly:
   fall on your face a few times.

Yes I understand this somewhat and thats the reason probably I am 
somewhat hesitating to reuse some of classes and thats increasing size 
of my code and probably duplicating my code.But again there are some 
good things, I can extend those classes in future and can bring down 
those modules if required without impacting any thing or making an 
changes to existing code.This is only plus point I can see 
now.Everything now is independent of each other. Finally at least I am 
enjoying doing something good rather than finding silly bugs and chasing 
developers for fixing those.


I will upgrade to 7.30 shortly if it saves me some memory.

Thanks Chris and Konstantin.Appreciate your guidance.

Large sites will use a single URL that ends up resolving the images
from some kind of data source. That data source might be a disk (e.g.
you could forward to the DefaultServlet) or a database (relational or

yourself.

I would use a servlet that gets the image identifier from the request
parameters or "path info" and then continues from there. As Konstantin
points out, using Tomcat's "aliases" feature means that these requests
may have to perform a linear search through all the aliases to find
the requested resource. If you write a custom servlet, it will likely
perform much better than that.
 this is what I am doing it right now and maybe bit different from what 
large sites do.I can see the point and can write filter which will scan 
the request url and point it to respective images directory and then 
serve it.



I store the images in the respective directory, for example for category 
A with subcategory sc, I store in C://A/sc and then write images names 
to the database.


and via jsp

I get this in this format,

img src ="A/test/{Imagename}" with image name coming from the database.

Below is way it looks in requests.

However I am not getting if I am writing the single servlet which 
resolves the images uri, how will it help in improving performance ? If 
Images are in different directories, isn't tomcat needs to scan that 
directory and resolve it ?


Initially I had a single directory,but though it would be nightmare in 
case of maintenance, so thought of refactoring it now.


>>>>

3. Having 200 aliases means that Tomcat would have to try 200
different prefixes for each resource lookup. Maybe it would not be
noticeable (compared to the other time spent in delivering a
response), but it still seems like a waste of time.

Why should it do resource lookup when I am telling it to look at the exact 
directory by giving it the exact name of the file ? In fact while storing also 
I am
giving it the exact directory path to where it needs to store ?

Do you believe my understanding the way aliases works is incorrect ?



2. It is possible to define a system property (via -D in the options

list at startup, or via catalina.properties file) and reference it as
${propname}.

This approach will require me to refactor my existing code,so I will think of 
using this in my next module.There are couple of things I am planning to get it 
dynamically ,but again somewhat scared if I can ever write thread safe 
servlets/classes which can serve multiple concurrent requests.Currently I have 
close to 50% of code which is reused.But I need to deal with this sooner the 
better else I am going to have war file which will be atleast 40mb in size with 
unmanageable number of jsp/servlets/beans.

Thanks Chris and Konstantio for replies.Currently I am on 7.027/7.011 and maybe 
after some days, I will upgrade to 7.030 or still better have one more TC for 
testing purpose.

Thanks Konstantin, it seems to be working perfectly fine.

This is how I am doing it now,

aliases="/UploadedImages=c:/UploadedImages,/st=c:/st,/sb=c:/sb,/UploadedImages/scr=c:/UploadedImages/scr,/UploadedImages/scyr=c:/UploadedImages/scyr,/UploadedImages/sem=c:/UploadedImages/sem">


Now I have one clarification, I am going need  close to 150 
categories(think of marketplace) and there will be fair amount of images 
upload which my users will be doing.


I expect the aliases to grow till 150 to 200 paths, do you feel this is 
correct.I am not sure as how large sites deal when they have heavy 
volumes of images getting uploaded on daily basis.


Do I need to cautious here on anything.

Good, except that you should really upgrade to the latest Tomcat 7.0
version. Plenty of security fixed have been shipped since 7.0.11.


I think now I understand as how aliases work, /UploadedImages is
the aliaspath and c:/UploadedImages is the docbase to which it
refers.

Is this understanding correct ?

/UploadedImages is the URL where resources in C:\UploadedImages can be
requested. The term "docbase" doesn't really apply as it has a number
of connotations that aren't appropriate here.


In manager app I see something called /files , not sure as what is
this ?

That is likely to be another webapp, but I have no idea where in the
manager app you are looking, so I can't really comment.

Remember that Tomcat will (by default) auto-deploy any directory in
the CATALINA_BASE/webapps directory -- even those that you don't
consider to be a legitimate webapp. So, if you have a directory called
"files" in there, then Tomcat will deploy that into "/files" and
possibly expose some resources that you hadn't intended to be
available via HTTP.

Thanks Pid for reply.
Unfortunately nothing  changed on my system.Even time was correct and I 
did not see any logged time event events anywhere in logs.


Just a js library which had close to 12 files in it from apache folder 
disappeared without a trace.But the good news was that JS Library inside 
the app war file did not get impacted.
Using that war file I was able to recover the library.Maybe its just my 
good luck.


Probably since library was inside war file, it did not get impacted.

Hi,

I have below code for catching DAO exceptions,but I feel its not correct 
way to do this,Can some one point me to some library which will capture 
all exceptions which my code will throw and works with tomcat. I 
implementing Model2 mvc pattern and to my surprise I am able to show

that no exception is also being thrown anywhere.All logs looks clean but 
DB is not updated.


import java.sql.Connection;

public interface DAO {

Connection getConnection() throws DAOException;

}

public class DAOException extends Exception {
private static final long serialVersionUID = 19192L;

public DAOException() {
}
public DAOException(String message) {
this.message = message;
}
@Override
public String getMessage() {

public void setMessage(String message) {

fixing that I somehow forgot to to use model 2 design(again my bad its hard to 
wire the brain to work this way when you can just make easy calls and then 
present data to the client and yet do MVC) and started working  old way and due 
to this db calls went into the servlet.For other module I am fixing this and 
will make action servlet which will read request uri and then do the 
appropriate action.I have almost visualised,inserts and deletes.Trying to find 
the way to see how to make edit work.I have around 10 images and around 10 
fields which I need to perists somewhere before final insert.

Re: Tomcat DBCP Connection pool issue

[Kiran Badi]

Probably waited too long for a connection. What does your pool 
configuration look like? Look in META-INF/context.xml or, I suppose, in 
conf/server.xml for  elements.


 type="javax.sql.DataSource"

   maxActive="100" maxIdle="30" maxWait="1"
   username="user" password="xxx" 
driverClassName="com.mysql.jdbc.Driver"

   url="jdbc:mysql://localhost:3306/mysitedb"/>

This is my configuration in context.xml Chris.

 I had a bug in my code  and I was not closing connection, I fixed it 
and now this is working fine.

an architectural comment: it's probably not a great idea to
obtain a database connection directly from your Servlet. Doing so
likely ties your business logic directly to both the servlet API *and*
the JDBC API.

If you want to switch to some other data source (e.g. a
non-JDBC-supported data source like MongoDB, Cassandra, etc.), then
you have to re-write your whole app. If you want to support Websocket,
then you have to completely re-write your webapp. If you want to
create an Android or Swing-based version, you have to completely
re-write your app. See the pattern here?


I know existing design is somewhat a kind of limitation,but again at 
this point ,its just to hard to implement this change.


Let me think over this.It will take sometime.

Subject: Protect JSP from Direct Access in Tomcat 7.0.xx

Hi All,

I need your guidance again.I have bunch of JSP's close to 100+ which I
need to protect it from direct access.

I have this mapping in web xml and this is not working,It seems that
probably i need to define a role first and then use below settings.But
unfortunately my app is open internet application which does not use
realm at all.


DenyAccesstoDirectJSP

sample.jsp
Sample confirmation JSP
*.jsp  GET
POST  


All my jsp's are residing in the webpages folder of project directory.I
know this is incorrect and probably gives direct access to jsp's.

So I have some clarification to ask,

1. is their a way to tell tomcat to not to serve direct jsp's probably
via web xml

2. Is their any extra setting that is required if I move my JSP's inside
web-inf.I created a folder under web-inf and create sample hello
world.jsp and then tried to invoke that jsp but got 404 message.

Looks like your mail session isn't getting initialized properly and you

This was the real issue.Caught the exception now and could see the root 
cause now and fixed it.Eureka you guys are genius and eye  for detail.


One more suggestion I need, I had mail.jar/mailapi.jar/pop3.jar/smtp.jar 
all over, they were in project library, tomcat lib and I remove all 
those reference and had just mail.jar in tomcat lib,bounced the server 
many times and only after that I managed to make this work.


How do you remove safely all reference without impacting the server or 
your build script ? Do you just comment out the reference of jars or 
your physically remove them from the folder ?
Now a days quite often my build fails if I remove or other jars,so want 
to learn this trick as well.

There are many, many frameworks that will make this easier for you (once

If you're well into your project and don't want to add a framework to it
you could write a simple servlet that uses an algorithm to map URI paths

could put your JSPs in myapp/WEB-INF/jsps.  Then have the servlet map a

Of course, that URL gives a 404: it's trying to access WEB-INF which is
never accessible via HTTP.  But it is accessible via
RequestDispatcher.forward() -- e.g.:


servletCtx.getRequestDispatcher("/WEB-INF/jsp/newjsp.jsp").forward(request, 
response);

This is kind of like what you said earlier that your servlets are
essentially doing, right?
No I did not do the way you mentioned.I just created a jsp under WEB-INF 
and invoked it directly and got 404.I think I now see what you are 
mentioning.

and its wonderful idea.Makes perfect sense now.Thanks Tim.



This isn't a great approach because you really aren't separating the
model from the view (all the app logic and display logic are housed in
the JSP -- a maintenance nightmare).  But if you don't have time to
re-architect the app now, it will hide the .jsp's from "direct access".
And it will put you in a slightly better position if/WHEN you do
re-architect it.

I think I am using kind of MVC pattern of course the one used around 6
to 8 years back.I am using jsp as view, servlet as kind controller and
then some beans/jstl and el to make my life easy somewhat. I would love
to work with frameworks like spring or struts someday.


They're free you know. :-)  But of course, free software doesn't add
hours to the day.  You're basically rolling your own MVC and that will
probably help you understand better what these frameworks do.  But move
away from this as soon as you can.  They've solved a lot of problems you
probably haven't even considered and they can make your applications
much less brittle if you take the time to learn them well.
Yup I have another project in mind which I plan to roll out soon 
probably either with spring or JSF.Maybe in a month or 2.I am fast 
learner and risk taker.





Ok  let me explain as what I need again,

I have form A with say about 10 fields, lets call this as jsp A. So in
browser bar it looks like http://localhost:8080/mysite/A.jsp


Ah, so you do want SOME of your JSPs to be URL accessible!  Well, if
A.jsp doesn't and never ever will have any dependencies on the
application's state then fine.  Maybe it's true today but I doubt it
will stay that way.  So it's probably better to be consistent and hide
this as well.


User fills this A.jsp and then clicks Submit button. It posts the form
to Servlet B which does insert in the database and then forwards the
request via request dispatcher to  C.jsp which has some confirmation
details in it.(Unique reference ids pulled out from DB).


So on submit, an HTTP POST is sent to http://localhost:8080/mysite/B.
Then servlet B does its work and essentially invokes:

ctx.getRequestDispatcher("/C.jsp").forward(request, response);

then C.jsp sends back the response using data from the session.

Is this right?

(btw, you know your app'ss requirements better than I, but storing all
data in the session isn't the only scope available.  It's likely that a
lot of response data needn't survive past the current request.  In that
case, setting request attributes would be better -- less memory needed,
less likely to pick up data that's inappropriate for the current
request).
Yup thats correct.I will explore this option of moving attributes to 
request.Thanks.

Now with my existing setup if I directly give url like

http://localhost:8080/mysite/C.jsp   I go directly to C Jsp which I
should not because its not suppose to be accessed directly.


Right.  Put C.jsp in WEB-INF, get a request dispatcher for
"/WEB-INF/C.jsp", forward to that and go home.

Yup got it.I think this should resolve my issue.

Javamail exception in tomcat 7.0.11

[Kiran Badi]

Hi All,

I have send mail servlet, which looks something like below,

protected void doPost(HttpServletRequest request, HttpServletResponse 
response) throws ServletException, IOException {

   String emailRecipient = request.getParameter("name");
//   String emailRecipient = "xxx";
try {
Message msg = new MimeMessage(this.session);
msg.setFrom(new InternetAddress("xxx"));
System.out.println(" remoteAddr is " + emailRecipient + "'");
for (int i = 0; i < 10; i++) {
msg.setRecipients(Message.RecipientType.TO, 
InternetAddress.parse(emailRecipient, false));

}

msg.setSubject("Test email");
msg.setText("Hello This is test mail");
msg.setSentDate(new Date());
Transport.send(msg); *(This is line number 60)*
System.out.println("Message sent OK.");
} catch (Exception ex) {
 
Logger.getLogger(MailSendingServlet.class.getName()).log(Level.SEVERE, 
null, ex);

}
}
}

and I have javamail reference declared in context.xml something like 
this one,

By "direct access" do you mean that http://host/myapp/sample.jsp is

that you don't want any .jsp URLs to be accessible to users?
No its not returning source code.I have couple of jsps where in I use EL

not something I want.

This isn't going to help you. Dump it.

Yup its not helping.



All my jsp's are residing in the webpages folder of project directory.I
know this is incorrect and probably gives direct access to jsp's.

So I have some clarification to ask,

1. is their a way to tell tomcat to not to serve direct jsp's probably
via web xml


If by "serve direct jsp's" you mean "don't return source code" then,
yes.  Put them under your web app's directory.  For example, if your web
app's context is 'myapp' then in tomcat it will be deployed under
/webapps/myapp.  You could put them directly in this directory
or group them under a separate directory; 'jsps' for instance.  Then
sample.jsp would be addressed as http://host/myapp/sample.jsp (or
http://host/myapp/jsps/sample.jsp )

Yup I have same setup.Still its not working.my bad.



2. Is their any extra setting that is required if I move my JSP's inside
web-inf.I created a folder under web-inf and create sample hello
world.jsp and then tried to invoke that jsp but got 404 message.


First of all, it's WEB-INF. Case matters.

Ok got it.



No, there's no special "setting" that will directly expose anything
under WEB-INF via a URL.  That's the part of the Servlet Spec.  It's a
Good Thing®.  However, if you're trying to make your JSPs inaccessible
via URLs, then you can move them there and have them indirectly accessed
using a servlet which forwards the request to them.  See
ServletContext.getRequestDispatcher() and RequestDispatcher.forward().
Yup I have lot many of request dispatchers in servlets.Almost all my 
JSP's are using data which is forwarded by servlets.I pull data from db 
via servlet, store it in session scope,forward it to jsp and in jsp 
access it via el.On logoff I remove attributes from the session.



Hopefully, you're trying to use or move toward the MVC (Model, View,
Controller) pattern.  If not, you should.  Google "MVC design pattern".
There are many, many frameworks that will make this easier for you (once
you learn them): Struts, Spring MVC...

If you're well into your project and don't want to add a framework to it
you could write a simple servlet that uses an algorithm to map URI paths
to JSPs then forwards to the JSP using a dispatcher.  For instance, you
could put your JSPs in myapp/WEB-INF/jsps.  Then have the servlet map a
URI such as /sample to /WEB-INF/jsps/sample.jsp (all relative
to /myapp).

http://localhost:8080/mysite/WEB-INF/jsp/newjsp.jsp

I just created folder jsp under WEB-INF and then added newjsp.jsp(this 
is hello world jsp) and then ran the file.I get 404 error. I am trying 
all this with netbeans.

This isn't a great approach because you really aren't separating the
model from the view (all the app logic and display logic are housed in

I am not able to figure out as why I not getting the url of jsp

2) if the browser /must/ send some information to the server as part 
of the URL, then there is /nothing/ that can be done on the server 
side, to stop the browser showing this information in the URL bar.


To illustrate this :
- imagine that the server sends a page to the browser, and this page 
contains a link like :
href="http://localhost:8080/mysite/getmyservice.do?id=my-very-secret-information";>click 
here


Then the user, just by moving his mouse above "click here", sees the 
content of that link at the bottom of his screen, in the status bar, 
right ?
And the user can right-click on "click here", and choose "copy link 
location".
And then the user can open another browser window, and paste this 
URL in the URL bar.
And then the user can modify this link before hitting the return 
button, so that the link now looks like

http://localhost:8080/mysite/getmyservice.do?id=some-other-information

hyperlinks with id appended to it.


Now I know both get/post can be broken if one wants it,thats all 
together is different case,but for now I need tidy and clean url with 
no id appended to it.


Does my requirement makes sense ?



Since you ask it that way, the answer would be no.

Step 1 : the browser contacts the server via a request with some URL 
(doesn't really mater which one at this stage, but in this first step 
there is no "id" yet).


Step 2 : the server does something with that request, and returns some 
response to the browser.  In this response, somewhere, the "id" to use 
in step 3 must be mentioned, or some other way to retrieve the id.


Step 3 : the browser sends another request to the server, in which 
this "id" parameter must be included (or some other way for the server 
to retrieve the correct id).


Step 4 : the server receives this second request, retrieves the id, 
and does something useful with it.


Now, at step 3, if the browser must include this "id" value in the 
request, it must include it somewhere.  This "somewhere" can be :


a) in the URL of a hyperlink.  In that case, the user will see the id 
parameter in the hyperlink, and in the browser URL bar when the user 
clicks the hyperlink.


b) in the body of the request. In this case, the user would not see 
the id parameter in the URL at step 3.  But it also means that the 
request in step 3 must be a POST request.

That is typically done with a

You cannot do that with a simple hyperlink. Clicking a hyperlink sends

Re: URL Rewriting

[Kiran Badi]

Thanks Hassan.

If you want 'clean' URLs you should get rid of the '.jsp' too, but ...



The bottom line is the value for 'id' needs to come from somewhere.
Your choices are:

1) Embed it in the URL for GET requests, either via query string or
as path info  (e.g. /story/data/17 ) and handle the security aspect
(if any) yourself

Kiran : I think this is what I am presently doing.


2) Use a form to POST the request with the id included (a bit clunky,
  same security issue)
Form will not work as data is dynamic and form I feel will not serve the 
purpose.


3) Save the 'id' in session and use that -- everyone sees the same URL
  e.g. /story/data but with unique data. Obviously, this doesn't work for
  a resource that's intended to be shared  :-)
Yup I agree, session is ruled out.I just dont have that much patience to 
figure the things out if I get some nasty behavior.I just dont have that 
level of skill nor time.
The way I have done this is ok for me, it serves my purpose and also I 
dont have the data which is kind of private.Its just that I was 
exploring if we can hide the id.

email recipients that are "somewhere else"
- receiving emails coming from other senders and destined to some 
local "email mailbox", and putting these emails in that mailbox, so 
that a local recipient can read them when they want


2) an interface library, which provides an API that makes it easy for 
your application to
- compose emails that you want to send out; and forward these emails 
to the email server, so that it can send them out
- connect to a mailbox, to read received emails that are waiting for 
someone to read them; and maybe parsing these emails, to extract 
something out of them; and maybe to forward one of these emails to 
some other mailbox.


(1) is a separate package (like sendmail, exim4, courier, and several 
others).  You install it, configure it and run it as a daemon.  Then 
you create "email accounts" with that email server, so that it would 
have "email mailboxes" with "email addresses" to which external 
people/programs can send emails.
This package can be written in any language, it does not matter; your 
programs will not directly call the internal functions of this email 
server, so it will make no difference whether it is written in Java or 
not.


(2) is an API library, and for that one it will matter what language 
it is written in, because your programs will need to call functions of 
this library, to send outgoing emails or to read incoming emails that 
are sitting in one of the email server's mailboxes.


Graphically :

(your.program <===> email library) < SMTP or POP3 or IMAP --> 
email server <> Internet


<===> are calls from your program, into functions of the library
<---> is a TCP/IP connection between that library and some email 
server, and the "language" used over that connection is SMTP or POP3 
or IMAP


It is similar to what you would use if your program needed to talk to 
another webserver:


(your.program <===> HTTP Client library) <--- HTTP or HTTPS --> web 
server
It does not matter if the web server is an Apache httpd, IIS, Tomcat 
or www.google.com, or whatever language that webserver is written in, 
or if it is local or remote.


Similarly, it does not matter which email server you are going to 
use.  It just needs to support the email protocol you want to use and 
which your library supports.


The /library/ is what matters.
And for Java, the one that comes to mind first is Javamail.
(It can help you composing ans sending emails; but I do not know if it 
can /read/ incoming emails).

Take a look this

I don't know if this is good ( or if it's useful enough for you )
because I don't have used it, but if I would like to work with GMail
in a enterprise enviroment , I would look this first
Jose,I do have bunch of domains with google apps,but I havent checked if 
I can reuse those with my application.Let me explore that as well.


Let me explain as What I want to do,

I have a web application which I am working on,in this application I 
have certain features (think daily deals site) ,and I have send out 
those daily deal information to my registered users via mail.In addition 
to this sometimes I have to receive mail on behalf of my users and then 
pass them to their mail ids.


This is requirement I have to work on now and for this I need some 
servers to send and receive mails.

Any feedback on apache james ?


I've never used it, so I can't comment. What I would ask is: why are
you are specifically looking for a Java-based mail server?

I was looking for open source server ,capable for serving atleast 5k 
mails daily to begin with.Since I am using java api, I am under 
impression that java based mail servers will have support for java api's.

If you are going to use Javamail to access a remote mailbox (even if
it's on localhost), then you can use any email server software that
otherwise meets your needs. Javamail can communicate with any POP3 or
IMAP server -- it need not be Java-based. You can even use Google Mail
as your email service if you want (for both SMTP/send and
POP3/IMAP/fetch).

Thanks David ,I will research java email server and Chris for replying,

High level requirement which I feel I need is, to send mail(ex pw reset 
mails, welcome mails, HTML Content deals mails etc), receive mails( yes 
I need to receive mails as well),


Integrate well with Tomcat means that it should not have more set up or 
communication issues talking to tomcat.I plan to use Javamail api's and 
read mail servers parameters via web xml resources section.

Do you want to send messages, receive messages, or both? Sounds like
you definitely want to send, but do you really need to receive?

When you say "integrate with Tomcat 7.0x", do you mean that you want
to run the "mail server" in-process with Tomcat? I would guess that a
separate process would be more secure, more reliable, and give you
more options. For instance, there are many tried-and-true mail servers
that are not Java-based that could certainly meet your needs as long
as you don't need them to be in-process. For example: sendmail, EXIM,
Courier, and others are all available as options through most Linux
package-managers.

can some one give me some  other names which I can check ?.

PS:I am going through apache james to see if it works for me.

Good, except that you should really upgrade to the latest Tomcat 7.0
version. Plenty of security fixed have been shipped since 7.0.11.


Yes , I will try to give a shot.But it will take sometime.But 
application is deployed in latest tomcat version 7.0.27 and this is my 
development server.

I think now I understand as how aliases work, /UploadedImages is
the aliaspath and c:/UploadedImages is the docbase to which it
refers.

Is this understanding correct ?

/UploadedImages is the URL where resources in C:\UploadedImages can be
requested. The term "docbase" doesn't really apply as it has a number
of connotations that aren't appropriate here.


Thanks for clarification.



In manager app I see something called /files , not sure as what is
this ?

That is likely to be another webapp, but I have no idea where in the
manager app you are looking, so I can't really comment.

Remember that Tomcat will (by default) auto-deploy any directory in
the CATALINA_BASE/webapps directory -- even those that you don't
consider to be a legitimate webapp. So, if you have a directory called
"files" in there, then Tomcat will deploy that into "/files" and
possibly expose some resources that you hadn't intended to be
available via HTTP.
Kiran : Yup, Had an empty files folder inside webapps and this was 
showing up.


Many thanks Chris,Appreciate your assistance.

You shouldn't put  elements in server.xml. Also, using a

Presumably you have an existing webapp that does the upload part: make
C:\UploadedImages into an "alias" for that webapp instead of creating
a second webapp for it.

Ok I will give try to create alias and see how it goes.

Thanks.
