Trouble running servlets using TomCat4.1.18

[Kamaleshwaran Sivalingam]

Hi,
I have trouble running servlets using tomcat4.1.18 in Redhat Linux. I have 
Apache 1.3.20 installed  which is listening on port 80. The TomCat  server is 
listening on  port 8080. The Apache server is used for serving php. so when i 
entered "http://localhost"; on the mozilla  browser, i get the index.php page.  

When i entered "http://localhost:8080"; i get the index.html page which is under 
the tomcat directory. When i click on a button on my index page i must get a 
servlet  which should be executed by the tomcat. But  I get the following error 
on my browser.

Not Found
The requested URL /examples/servlet/PeatPlot was not found on this server.


Apache/1.3.20 Server at _default_ Port 80


So it  was served by apache on port 80.
How do i redirect this to port 8080(TomCat)? can you help  me out?

Thanks,
kamaleshwaran Sivalingam

Help: running servlets on IIS

[Raghusimha Sudhakara]

Hello, I had a very simple question that I have been struggling with and
any help on which I would greatly appreciate. I am trying to run
servlets on IIS using tomcat below IIS. I have an external *.properties
file that contains all the initial arguments for my servlet. Can anybody
tell me how I can get this properties file loaded every time the servlet
is invoked by the browser.

I tried giving the properties name and file location in the web.xml file
in the init param section but I still get an error message in the
browser saying it did not find the file. I have tried both
C:\jakarta-tomcat and, the partial \WEB-INF\ as the param value.
I heard an other option is to extend init and load the file. Details
regarding any of this will be greatly appreciated. I am new to most of
this stuff Please help!!!

Thanks.

running servlets that invoke DLLs (Native Methods)

[Mark Hansen]

I have a servlet that calls a Native Method (stored in a Windows DLL).
Tomcat can't seem to find the DLL even though it is on the system path (PATH
environment variable).

Does anyone know how Tomcat finds Native Methods that are called by
servlets?

Thanks,

Re: Problem Running Servlets

[Jason Johnston]

Sorry, the structure I meant was 

/core/WEB-INF/classes/test/HelloWWW

Re: Problem Running Servlets

[Jason Johnston]

Try running your servlet from the address:

http://localhost:5001/core/servlet/HelloWWW


I ran into this problem and found several things that I changed to get it to work.  

1.  I moved it into a test directory and made the servlet part of a test package
  i.e.  package test;

I could not get the servlet to run from (in your case) /webapps/core/HelloWWW.  I had 
to do what I mentioned in 1.  As I gather this has to do with servlet mapping.  I 
ended up with a structure more like /webapps/core/test/HelloWWW

2. I deleted my web.xml file and let tomcat use the defaults.


I have gotten many of my servlets to work this way however, I'm still having trouble 
with tomcat finding my custom web.xml files.  I constantly get the error in the log 
that the web.xml file is missing for my webapp when it certainly isn't.  I've found 
other people with this problem but no solutions.  Apparently there is also a bug under 
2000 with root context and web.xml, but if you're experiencing that tomcat really 
shouldn't work at all.

Hope this helps, if anyone finds a solution to the missing web.xml problem please let 
me know.

Problem Running Servlets

[Smalley, Howard]

Hi All

Perhaps someone can help me with this,

I'm trying to get a very simple servlet to run, I'm using Tomcat 4.0.3 on
Windows 2000. I've set up my application in the webapps directory, then
added my servlet name to the web.xml in this directory.

Tomcat starts up ok, but when I try to run the servlet using the path to the
servlet,
eg, http://localhost:5001/Core/HelloWWW I get an HTTP status 404 error,
requested resource (/HelloWWW) is not available.

Interestingly if I try and run this servlet by adding,
Execute 

to the examples html page, I'm then asked if I would like to download the
file?

I'm sure this is a simple configuration problem.

Any help would be greatly appreciated.

Thanks
Howard

Re: Running Servlets on Tomcat4.0

[Steve Vu]

Here's a snippet from the sample web.xml file from the
Tomcat docs.  At the bare minimum, you just need to
define the servlet name, the class associated with the
servlet, then map the servlet to a URL pattern:




  controller
  
This servlet plays the "controller" role in
the MVC architecture
used in this application.  It is generally
mapped to the ".do"
filename extension with a 
element, and all form
submits in the app will be submitted to a
request URI like
"saveCustomer.do", which will therefore be
mapped to this servlet.

The initialization parameter namess for this
servlet are the
"servlet path" that will be received by this
servlet (after the
filename extension is removed).  The
corresponding value is the
name of the action class that will be used to
process this request.
  
 
com.mycompany.mypackage.ControllerServlet
  
listOrders
   
com.mycompany.myactions.ListOrdersAction
  
  
saveCustomer
   
com.mycompany.myactions.SaveCustomerAction
  
  
  5



  graph
  
This servlet produces GIF images that are
dynamically generated
graphs, based on the input parameters included
on the request.
It is generally mapped to a specific request
URI like "/graph".
  






  controller
  *.do



  graph
  /graph

Running servlets on tomcat 3.2.1 with IIS 5.0

[Boris Maretic]

Hi

Please can anyone help me about this problem.

I have just installed TOMCAT 3.2.1 (standalone) on WIN200 and it works.
I have setup tomcat as a JSP engine for IIS. 
But now I would like to make tomcat as a SERVLET engine for IIS.

System:
WIN 2000
IIS 5.0
TOMCAT 3.2.1
C:\INETPUB\WWWROOT\MYAPP\ is place where application files are situated 

A part of Servlet.xml file which I added is this:
-
 

--

I have used automatically generated file uriworkermap.properties-auto.
The part of that file is:
-
#
# Default worker to be used through our mappings
#
default.worker=ajp12

#
# Root context mounts for Tomcat
#
/servlet/*=$(default.worker)
/*.jsp=$(default.worker)
---

JSP files are executed by tomcat  correctly but servlet not.Why?
How to run servlet from IIS?

Re: Running servlets in tomcat

[Richard Draucker]

The sub-directory in your url is controlled by the mapping in your server.xml 
file under the tomcat/conf directory.  Look in server.xml, near the bottom.  
You must have a mapping (servlet context) setup for satheonline or Tomcat 
won't be able to find the servlet. 
If you have no mappings setup, i.e. you're using the default, just get rid of 
the satheonline in your url and it should find the servlet just fine. 
Also, Tomcat comes with a "test" context that contains their 
HelloWorldExample.  If that is the example you're trying to run, then just 
replace satheonline part of the url with "test"

Running servlets in tomcat

[AN Sathe]

hi
I m using tomcat 3.1 but I am unable to run servlets in tomcat

Is there any configuration problem.

I have added the following line in my /tomcat/binary/conf/server.xml file
and created a webapp "satheonline " under /tomcat/binary/webapps/




Then I have created the following directory structure under sathonline:

satheonline(contains all html files )--Meta-inf
 --web-infclasses (contains
servlet class files)

Besides the web.xml file in web-inf contains the following

 

   helloworldexample


HelloWorldExample



The server starts fine. But when I type
http://localhost:8080/satheonline/servlet/HelloWorldExample it gives a 404
error

what is missing ?

thanks

Re: Problem running servlets on Apache/Tomcat

[Vinay Menon]

Make sure that your connectio pool class is under the correct directory
structure under WEB-INF/classes. For eg. if your ConnectionPool class is in
uk.co.youconame.dbclasses.ConnectionPool make sure that it exists under  the
directory

WEB-INF/classes/uk/co/yourconame/dbclasses/

Re: Problem running servlets on Apache/Tomcat

[Boris Niyazov]

If you use packages as jar files you should place them ether in 
WEB-INF/classes/lib (for a particular webapp) or $TOMCAT_HOME/lib. The latter 
will assure that all your webapps will have access to the classes in the jar.

Problem running servlets on Apache/Tomcat

[Priya Gupta]

Hi
  This query has been posted on this list quite a no.
of times and even after going through the archives I'm
still stuck up with this problem!
  To start with the configuration... I'm working
Windows 2000 professional with Tomcat 3.2.2 and Apache
1.3.20. The backend is Oracle 8.1.6.
  I have an application called 'portfolio' for which I
created a folder in C:\TOMCAT_HOME\webapps called
portfolio with a hierarchy of other directories
required, like
C:\TOMCAT_HOME\webapps\portfolio\WEB-INF where I
copied the web.xml and
C:\TOMCAT_HOME\webapps\portfolio\WEB-INF\classes where
I put all the servlet classes. I have put all the
other files like htmls, images etc. in the
C:\TOMCAT_HOME\webapps\portfolio directory! and not to
forget the C:\TOMCAT_HOME\webapps\portfolio\lib dir.
for all the jar files and Orcale driver...
   I have made changes to my servlet.xml file also to
let tomcat recognize my application! Putting in the
'context-path' stuff and have edited the web.xml file
to map the servlets
   Now I can execute my servlets but cannot run
them... coz when I try exceuting them I get an error
'ClassDefNotFound: ConnectionPool/ConnectionPool'
   Now CoonnectionPool is actually a package(as the
name impies) that i created to make a connection to
the database. Its also in the classes dir. When I
execute the servlets I dont get any errors as to
"unable to find ConnectionPool", so I presume that
they are in the Path.
   Now I'm really stuck up and am unable to find the
real problem! May be someone out there whos done
something similar can help me solve this
Thanks a lot in advance

Problem running servlets on Apache using JNI

[Brenda Mijares]

I found the following message, yet no reply ... I am having the same
problem except I'm running on Linux..
Does anyone know the solution, to make a basic call to a native method
from a class called from
a servlet??? Do you really need to change the workers.properties file...

Appreciate any help.

thanks,

Brenda

 Subject:  Tomcat + JNI
 Date:  Fri, 17 Nov 2000 16:58:51 +0100

 Hi,

 I have just installed Apache1.3.14 + modssl + tomcat 3.2b5 on
 Solaris 2.6
 and am trying to call a native method from my servlet (this worked
 fine
 under JavaWebServer2.0).

 The shared library is definitely being loaded (ie no exception is
 thrown when I tried
 to load it separately, the lib is on the LD_LIBRARY_PATH etc) but
 "UnsatisfiedLinkError"
 is still being thrown indicating the implementation of  the native
 method is not
 found.

 I havent done anything special to tomcat for JNI, I was a bit
 baffled by the purpose
 jni_server.xml and jni_workers.properties files! I only need to call
 a C program from
 within a class called by the servlet, don't need to call java
 methods from the native
 code.

 Has anyone come across anything like this?

 Many thanks,

 Mike.

running servlets on IIS

[Robin Imrie]

Hi,

I am running tomcat 3.2 and IIS4 on NT Server 4.

I am using IIS to deliver asp pages and want to use tomcat to run my
servlets. I have set-up tomcat to run in process. My first servlet is used
to process a form using the Post method, when I press the submit button I
get the following error back:

HTTP Error 405
405 Method Not Allowed

The method specified in the Request Line is not allowed for the resource
identified by the request. Please ensure that you have the proper MIME type
set up for the resource you are requesting.

What is the best way to configure Tomcat and IIS so that I can run servlets?

When I run my servlets should I use a full URL path or should I be able to
use a relative path.

thanks

Robin

Tradeoffs: running servlets + EJB in same VM or different VM?

[David M. Karr]

In a J2EE scenario, is it reasonable to consider both the possibility of
running the servlet container and the EJB container in the same VM, and running
them in different VMs?  I would guess the former would give a small plus to
performance, whereas the latter would be a small plus for scalability.

If you are running tomcat standalone and have not changed the 
default port settings then
http://localhost:8080/user/servlet/hello
If you have integrated Apache and tomcat then 
http://localhost/user/servlet/hello

> 3. in what way should i configure the web.xml file ??

 There are two types of web.xml file. The default which is global
 to tomcat i.e. the one in tomcat\conf. I believe from 3.2 onwards 
 this is no longer read by tomcat so you can forget about it. 
 You can also and should define a web.xml file for each web app.
 This should be deployed in the WEB-INF dir of your app (not the 
 classes dir)
 Take a look at the web.xml file in the examples directory. 
 Also, chapters 9,10 and 14 of the Servlet API spec is the best place 
 to learn how to configure web.xml. It is available at
 http://java.sun.com/products/servlet/

 Hope this helps
 Andrew

Re: [NEWBIE] Running Servlets on Tomcat

[Ashant Chalasani]

Ritin,

The complete instructions to configure your Tomcat environment can be found 
in the /docs directory under your tomcat root.  Additionally the servlet 
specs also are helpful in describing the web.xml file etc., you'll find that 
@ http://java.sun.com/aboutJava/communityprocess/review/jsr053/index.html

Quickly...

>c:\tomcat\webapps\user\web-inf\classes\hello.class
>1. Where to store the .class files ?

This is the right folder to store your .class files.  Don't forget to change 
the context path in server.xml file (in this case to point to /user 
directory)

>2. what link to give to the browser ?

The browser needs to call something like this...

http://localhost:8080//servlet/
Note that this path holds good only for invoking .class files, not regular 
htmls or jsps etc.

>3. in what way should i configure the web.xml file ??
> ( there is already a web.xml file in tomcat\conf\..)

The web.xml is the Deployment Descriptor file for your web-app, you can find 
all config. details in the Servlet Spec.

running servlets

[Winifred Sanchez]

I copied some sample servlets from the examples context into another context I made to 
see if they would run. But they won't run. I have placed the servlets inside the 
WEB-INF/classes directory just like in the examples context and also made a web.xml 
file under WEB-INF with the following lines:



 
   

SessionExample
 
 
SessionExample
  
   
   
 
SessionExample
 
 
/SessionExample
 
   



I'm trying to access the servlet with:
http://hostname/context/servlet/SessionExample

but I keep on getting

Error: 404

Location: /context/servlet/SessionExample


How do I make the servlet work?

I am using Tomcat 3.1 with Apache handling static pages.

Thanks.

Hi,
1.
Pl add servlet mapping tag.Like below

  hi 
  /hi 
  
2.
Check out for the server root and port number .
3.
Check for the classpath of hi.class

Good luck,
