Re: Tomcat Bug?

[Drew Jorgenson]

OK, look inside TOMCAT_INSTALL_DIR/work/Catalina/localhost (or whatever
other virtual host you may be running) delete the cached file in
question or all of them and restart tomcat ;-)

Re: Deploying a Servlet to Tomcat 5.0

[Antony Paul]

You have to add a mapping for the servlet in the WEB-INF/web.xml file.
Look at the examples directory in webapps for sample.

Deploying a Servlet to Tomcat 5.0

[Harsha perera]

Hi,

I have been trying to deploy a simple servlet to
Tomcat 5.0. Tomcat is installed on WIndows XP.

This is what I did:
1. Created a directory structure under 
   $TOMCAT_HOME\webapps as follows:
   ROOT\WEB-INF\classes

2. Moved the class(HelloServlet.class) to the
   above created directory.

3. Bounced Tomcat.

4. Attempting to access the class as 
   http://localhost:8080/servlet/HelloServlet gives 
   me the error:
   HTTP Status 404 - /servlet/HelloServlet



type Status report

message /servlet/HelloServlet

description The requested resource
(/servlet/HelloServlet) is not available.


Please advise on how I should be deploying this simple
servlet. 

The servlet is code is given below:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

/** Simple servlet used to test server.
 *  
 *  Taken from Core Servlets and JavaServer Pages 2nd
Edition
 *  from Prentice Hall and Sun Microsystems Press,
 *  http://www.coreservlets.com/.
 *  © 2003 Marty Hall; may be freely used or
adapted.
 */

public class HelloServlet extends HttpServlet {
  public void doGet(HttpServletRequest request,
HttpServletResponse response)
  throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType =
  "\n";
out.println(docType +
"\n" +
"Hello\n"
+
"\n" +
"Hello\n" +
"");
  }
}

Re: Tomcat Bug?

[Parsons Technical Services]

As far as I know.
Under IE options for the settings in the files section you can set that to 
check for a new page on each visit.

Pressing F5 is suppose to do a new request.
Also I remember some mention about file dates. Make sure date on new file is 
later than on original file.

There have been several threads on this but each had a slightly different 
twist. Check the archives.

If you delete the app does the page still respond or give you an error?

Re: Meaning of threads

[Sean M. Duncan]

What is the impact of having apache httpd allow keep alive requests when
using the AJP connector to tomcat?  Does this have any impact on
tomcat's thread usage?  How well does httpd itself deal with keep alive
pipelines under a heavy user load?

Re: Does JDBCRealm close connections?

[Parsons Technical Services]

In a quick scan of the source (4.1.30). The realm does not use pools. It 
opens the connection upon authentication. Then closes it right after. All in 
the same method.

There is a note about adding pooling, and this may be one reason why.
If you have a limit on the number of connection your dbengine can support 
then this may be the cause.

So for the last question, yes, it would keep opening the needed connections 
for logins. But it closes them promptly after retrieval of the data.

Hey there--just wondering if JDBCRealm with Tomcat 4 ever closes
connections it opens...I'm assuming it can open up more than one
connection to the database if traffic gets heavy (because we think we're
seeing that, though it's hard to tell for sure).  If so, when does it go
about closing those connections?  I was reading about it here:
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/realm-howto.html#JDBCRealm
We're trying to debug a nasty problem, and we're wondering if a couple
hundred folks try to log in at the same time and there are only about
that many database connections that can be pooled (and a bunch of the db
connections are already in use by the web app), then does JDBCRealm just
keep opening up more and more connections to the database?
Thanks,

Tomcat does not evaluate jspf extension files

[Norris Shelton]

Everytime I try to use a .jsfp extension for a file, tomcat does
not evaluate it.  Comments come out, code is displayed, etc.

I also ran into this thread:
http://www.javakb.com/Uwe/Forum.aspx/java-programmer/13915/Tomcat-5-EL-Expressions-in-jsp-inlcude

He happened to be using the .jspf extension also.

I tracked it down to this in the Tomcat web.xml:

jspf
text/plain



Is the problem because .jspf is not mapped to the jsp servlet
like .jsp and .jspx are?


jsp
*.jsp



jsp
*.jspx

RE: Sending email with zip file attach problem

[Daxin Zuo]

Thanks for the reply. So I have to output the file.
If, in jave, there is no way to upload the file and attach the file
directly, it seems strange.

It is an example of sending bulk mails with
attachment.
You have to write the uploaded file into a temporary
directory.

See the attachments.  I hope the example could be
useful.

Multiple hit from one user problem

[Dola Woolfe]

Hi,

Since this doesn't appear to threads issue I'm taking
it out into a separate thread.

I'm running TC 5.4.4 on port 80 with no Apache on XP
Pro. A colleague on mine has an Excel spreadsheet
attempts to perform about 2000 very short queries,
most likely in sequence. About half of the way
through, the server stop responding to him. When he
then uses the browser to go to one of the pages served
by the server he gets a "page cannot be displayed".
After about 2 min (we never really timed) things
return to normal.

Any suggestions?

Many thanks in advance,

Aaron Fude

"In my experience however, this does NOT work well in
a high traffic situation."

I'm sure you're not saying that "Tomcat does NOT work
well in a high traffic situation". You are just saying
that in a high traffic situation one should turn off
keep alives.

Am I guessing correctly that I have only a few
persistent visitors (such as an office web application
that is a front end to a database) then turning keep
alives on will cause the data to be returned to the
user more promptly.

But if, say, you are running an eBay type site, keep
alives should be turned off.  Any single user will
suffer a little but the traffic will be handled
better.

Re: Tomcat Error: java.lang.NoClassDefFoundError:

[Kathie Manson]

Hi QM,

Thanks for your response.  In between Tomcat working and breaking, I
had installed Cactus.  I think that actually changed something,
somewhere on the classpath which wasn't actually in tomcat's directory
structure.  When I reinstalled tomcat, I did completely remove it,
then reinstall.

I've managed to fix the problem now, by removing my Java SDK and
reinstalling that.  Not the world's greatest solution, but it worked.
And, yes, that was the full stack trace from catalina.out.  The "root
cause" was the java.lang.NoClassDefFoundError.

Thanks for your help,
Kathie.

increase
the thread count - if memory suffices?

Unfortunately not. IMHO threads are over used and over rated.
Have a look at the reasons THTTPD and Zeus webserver were created.
I was told that the 'Java Servlet Spec' (I think this was the one) 
requires
one thread per connection. I can understand the reasoning behind this,
as it makes the implementation much easier.

In my experience however, this does NOT work well in a high traffic 
situation.
It makes NO sense for a machine to need to deal with 1000+ threads. 
(Unless
of course you have an E15000 in the basement with 1000 processors). I 
had
major problems with Debian Woody as the supplied Glib C as I was unable
to get java to start more than 250 threads. Sarge was better in that it 
supported
the new linux threading library out of the box. I do not have any 
experience with
Solaris or Windows when dealing with that many threads.

You need to disable keep-alives, becuase if you don't you end up 
wasting a lot
of threads that just sit waiting for the next request on that 
connection - meaning
even more threads just hanging around.

The scary thing is, imagine something hangs on the backend for 30 
seconds, and
then all your 1000 threads start trying to do something at once You 
will end up
with a load of 1000 and ALL your requests will take a long time to 
return.

It may be interesting to replace the http connector for tomcat with one 
that uses
"select" and uses 'threads' as a type of worker pool. This way, you can 
deal with
all the connections in the select loop (incl. keep-alive) and still 
have the advantage
of not needing to remember state due to the worker threads to the back 
end...

Re: Meaning of threads

[Filip Hanik - Dev]

no, think about it a little bit longer, what does a keepalive connection do,

it hogs one thread per client, not per concurrent user. so now other clients 
will be stuck waiting cause you have keepalive turned
on, and a user is sitting idle doing nothing, but yet, taking up server 
resources

Re: Meaning of threads

I would also consider turning of keepalive. Unfortunately tomcat (and 
apache)
both setup one thread per connection. You may be able to use squid as a
reverse proxy if you are having load/ number of connection/ thread 
problems
depending on your application

Wouldn't it make more sense to enable keep alive connections and increase
the thread count - if memory suffices?

Even if not, the keep-alive timeout should be decreased instead of disabled
all together.

Additionally I'd like to see tomcat to be able to drop keep-alive connection
exactly then, when all threads are busy and a new connection is to be
etablished.
That would give us the benefit of keep alive connections - faster data
delivery for users - as well as optimal thread usage even on small thread
pools.

What is your opinion?

This is completely offtopic.

Some ideas:

- If you only have one virtual host on the Windows box, then start a
webserver on the Linux box and set it to redirect to the IP address of
the windows machine.

- Start a proxy on the Linux box and have it hand all requests to the
Windows box.

- Add some NAT rules to the linux box's netfliter rules to send all
connections (depends on root access and relevant kernel modules being
installed)

# very much untested and to be used at your own risk!
cat /proc/sys/net/ipv4/ip_forward   # check what it's set to now
echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -I PREROUTING -t nat -p tcp --dport 80 -d  -j DNAT \
--to-destination 

To revert back to previous state, write the previous value of
/proc/sys/net/ipv4/ip_forward back to it and then replace the '-I' in
the iptables command with a '-D'.

bizarre authentication problem

[Andy Kriger]

I have an Tomcat server on an internal network configured to require
basic authentication. This works fine when I use IE or Java code to
access a site, but when I try to access the site using Firefox, the
user/password is never accepted. I have packet sniffed the GET calls
from both IE and Firefox and the Authorization header is the same for
both. I can access the Tomcat Manager using basic auth and external
sites with auth so it's not entirely broken. Tomcat has
maxKeepAliveRequests set to 1 (to deal with a .NET SOAP interop
problem) - that's the only oddball config in Tomcat.

I realize this is more likely a Firefox problem than a Tomcat one, but
I'm wondering if anyone has seen behavior like this.

This is the diff between the IE HTTP headers (<) and the Firefox HTTP
headers (>)...
< Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,

"Error allocating a servlet instance" caused by ClassCircularityError on java.util.Date with Tomcat 5.0.28

[Ian Stevens]

I have been trying to get our servlet working with Tomcat5.0, without much
success.  The servlet works flawlessly in Tomcat4.0 and Tomcat4.1, although
dropping the same WAR file in Tomcat5.0 on Windows with JDK1.4.2 (on two
seperate machines, even) produces the following stacktrace:

Re: precompilation and JSTL

[Marcus Beyer]

Tim Funk schrieb:
Is your web.xml using the 2.4 declaration?
Yes it is.
The problem has to do with precompilation, because it works if I deploy 
the JSPs instead of the servlets.

Example: 
The precompiled Java code looks like this:
_jspx_th_c_out_1.setValue(new String("1 + 2 = ${1 + 2}"));
Whereas the Java code compiled after deployment looks like this:
_jspx_th_c_out_1.setValue((java.lang.Object) 
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("1 + 2 = 
${1 + 2}", java.lang.Object.class, (PageContext)_jspx_page_context, 
null, false));

Why is it different??

Re: precompilation and JSTL

[David Smith]

Just a thought: 

Last I knew using the j2ee jar w/ Tomcat == EVIL.  You can either use 
the j2ee distribution on Sun's site OR Jakarta Tomcat (w/ j2sdk, not 
j2ee), but never j2ee and jakarta tomcat together.  It'll create some 
really ugly version conflicts.  If you use jakarta tomcat from 
jakarta.apache.org, use the jar files that have the specific functions 
you need instead. 

For jstl, that would be the standard-1.1 tag lib available here: 
http://jakarta.apache.org/taglibs/index.html.  D/L the standard taglibs, 
drop the jars in your WEB-INF/lib directory, and include the taglibs in 
your web.xml per the docs.  Restart the context and your done.

Sending email with zip file attach problem

Hi,
   Please help. Any sugestion is welcome. In my web page, users send email
with attachment, so upload is related. I can provide the file in either a
byte[] array, or in an inputstream. I try to send the attachement with
JavaMail(I know there is email api in Tomcat-Common. But I have no a good
example).

--- my code in a function in a servlet  ---
DiskFileUpload upload = new DiskFileUpload();
List items = upload.parseRequest(request);
Iterator itr = items.iterator();
item = (FileItem) itr.next();
.
//- now it is a attachement. 
InputStream istrm= item.getInputStream();
... 
MimeBodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setDisposition(Part.INLINE);
messageBodyPart.setContent(strBodyText, "text/plain");
MimeMultipart multipart = new MimeMultipart();

NO metter what file it is, the attachement received is ATT00211.txt.
I the file is a text file, the contents are correct.
if the file is a small zip file, it adds the lines as following in attached
file:
Content-Type: application/zip; name=idmeta.zip
Content-Disposition: attachment; filename=idmeta.zip
Content-Transfer-Encoding: 7bit

Is it best to encrypt the whole cart or just part of the cart?

Start Tomcat 5.5.4 in the Background with No Console (Windows)

[Matt Mejaski]

Hi all,
 
I'm wondering -- is there a way to start Tomcat 5.5.4 in the background on
Windows, without seeing the console, and without running it as a service?
 
Here's my situation:
 
I have a webapp running that sometimes needs to access network folders that
are only mapped when the user logs in to windows.  If I use a service to
launch Tomcat, it starts using the SYSTEM account, which doesn't have access
to the network drives.  Now, I know I can change the "Log On As" to user a
local account, but that also means I have to change the local account's
security privileges (to allow that account to run services), etc., which is
not a viable solution for me.
 
Instead, I was thinking that I could just start Tomcat in the background
when the user logs in (by putting something in the Startup folder or
something like that).  That way, Tomcat would be launched by the user, and
then it would be able to access network drives.
 
But, I don't know if there is a way to start Tomcat without the console
visible (so that Tomcat's execution is still transparent to the user, as it
would be if it were run as a service).
 
I guess I would also have to figure out a way to have the shutdown script
called when the user logs out.  That could be a pain as well, couldn't it?
 
 
Does anyone have any thoughts on this?
 
 
Thanks,
Matt Mejaski

out of memory error with more than a few sites

[Helmut Eggebert]

Hi,
I am getting an out of memory error when I start Tomcat.  I read posts on 
this in the past and followed some instructions to increase by min and max 
memory settings in catalina.sh.  I have 1028 MB on this server and so I 
increased the min to 128 and the max to 768.

The server was working fine when I had a few test sites on it.  I am 
currently using Apache httpd 2.0.52, Tomcat 5.0.28 and mod_jk2 configured 
with workers2.properties and so that tomcat can listen to apache requests.  
Apache httpd serves static files and Tomcat
is set to work on jsp's with the directive:
JkUriSet worker ajp13:localhost:8009

The problem showed up when I started migrating some sites over and increased 
the number of hosts significantly.  I created 80 VirtualHosts in httpd.conf 
and 80 hosts in server.xml.  Then I created 80 corresponding directories in 
webapp, each with META-INF and WEB-INF subdirectories.

Even though all these directories and subdirectories are empty, when I start 
up Tomcat, it tries to deploy them all and throws the out of memory error.  
If I remove most of the hosts in server.xml, everything runs fine again.

My goal is to have these sites each with a large number of static pages and 
only a few jps's which are Lucene's search.jsp and results.jsp.  After this 
I want to have these sites each has a portal component using Jetspeed 2.

I know that if Tomcat was not in the picture this server would be able to 
handle many more sites, but is 80 hosts with only a few jsps in each too 
much for Tomcat on an average modern Web server?  How can I optimize this?

Below I have included code snippets of my httpd.conf and server.xml and 
workers2.properties.

Thanks.

Re: sharing webapplication

[Dakota Jack]

You can have the various application URLs point to the same webserver
app, as Parsons pointed out.  However, why don't you want them to
share, except the "skin", everything on the website?  As long as the
"skin" is different, they won't know they are sharing anything.

Re: sharing webapplication

[Parsons Technical Services]

Way out on a limb here. (Assuming) If you are having three customers then 
you have three URLs. If this is true, maybe you could use the alias and 
setup something like this:

secure.companya.com
secure.companyb.com
secure.companyc.com
where all three are pointed to the same app. I have NOT done this and am not 
sure it will work.

But the way the documentation reads it should. From there have the 
secure.company.. added to the dns on each domain to point to the server.

TrustManager

[Quenin Bertrand]

Hi,
I'd like to know how setting a custom TrustManager in Tomcat 4.1.31. I have 
my custom provider installed and working ok. I tried to override 
"ssl.TrustManagerFactory.algorithm" property with my custom 
TrustManagerAlgorithm but tomcat seems to ignore it ... The only thing i 
achieve is to set a custom TrustStore with javax.net properties ... But i want 
a dynamic (CRLs, OCSP, etc.) TrustStore, not a static one ...
I can't find any information about TrustManagers in documentation.
Any help would be greatly appreciated.
 
 
BQ.

I pretty much agree with everything Harry says and I do so "in spades"
as they say.  You can, as a tip, make debugging JSP easier by putting
the whole page in a try/catch exception trap.

ant install fails

[Anil Philip]

Hello,

The build.xml supplied in the Tomcat 5.5.4 (Windows XP) documentation has
this line in the 'install' target:

   localWar="file://${build.home}"/>

 

Following the "development processes" Tomcat document, when I do an: ant
install

I get the following error:

 

C:\CRUDRE\build.xml:369: java.io.IOException: Server returned HTTP response
code

: 401 for URL:
http://localhost:80/manager/deploy?path=%2Fcrudre&war=file%3A%2F%

2FC%3A%5CCRUDRE%2Fbuild

 

However 

- doing a google search it says this 401 error is an authentication problem
but I am able to run the manager from the Start menu and in the
build.properties, I specify the same password/username that I did in the
popup dialog.

- when I did an 'ant all', it built successfully.

RE: connection Pool leaking - how to detect it ?

[Mike Curwen]

I use the logAbandonded in our test server, and I find the log messages in
catalina.out.  The log message includes (as part of a stack trace, so you
will have to inspect the output a bit) the JSP page or class (and line!) in
which the connection was opened.

Here's an example:

DBCP object created 2005-01-24 09:09:33 by the following code was never
closed:

Here they have given 3 parameters to specify to control leaking  such as
removeAbandoned, removeAbandonedTimeout, logAbandoned
 
1) Is there any way to detect in which program / connection, resultsets etc
are not closed. I tried my best not to keep it open, but in case by mistake
it happend to be then how i can detect it ?
 
2) Also what is the meaning of logAbandoned - where i can see the log of
this ?

RE: IIS 5.0 + ISAPI filter + tomcat

[Warron French]

Ramien, I have checked and found that there was a virtual directory called 
tomcat (which is what the ISAPI filter is configured with.
 
In the Vritual directory I have the following files:
isapi_redirect_1.2.5.dll
jboss-connector.reg
uriworkermap.properties
workers.properties
 
 
Here is the content of jboss-connector.reg ==
Windows Registry Editor Version 5.00

Redirector]

Hi warron, did u check the for the isapi_redirect.dll in your jakarta (virtual 
site in the IIS) ?, after that you have to set up the wrokers.properties file 
in the Tomcat directory and the uriworkermap.properties.

Tell me if you have  done this, if not I can give you a paper that I found on 
the Internet with the instructions for right configuration of the IIS 
redirection.

Good luck.

IIS 5.0 + ISAPI filter + tomcat
Is this an appropriate list to send my questions for IIS 5.0 ISAPI filters and

 tomcat?  Running on a Windows 2000 Terminal Server?



I am having problems with controlling the redirection of a website.



http://www.acf.hhs.gov/programs/core/hsrc/



However, I was asked to change this the headstart website to redirect to this

 site instead, 

http://www.acf.hhs.gov/programs/opre/hsrc/



Well, I went into IIS and looked up the site's configuration, clicked on the

 Home Directory tab and set the radial option from "Directory on this system" to

 "URL redirection" because I thought this was the correct way.



http://www.acf.hhs.gov/programs/opre/hsrc/ that

 link BACK to the headstartresearchconf.net... but as you would expect since I

 chose the radial option "URL redirection" the site simply loops back.



http://www.acf.hhs.gov/programs/opre/hsrc/ 
http://www.acf.hhs.gov/programs/core/hsrc/. 
 



http://www.acf.hhs.gov/programs/opre/hsrc/, but then the links on that site

 can't make it to the headstartresearchconf.net references they are trying to

 reach... because I removed the ISAPI filter named "tomcat."



I really need to fix this mess, because it is a heavily used site.









http://www.acf.hhs.gov/programs/core/hsrc/  with the ISAPI filter in place, but

 I don't know what is generating the URL redirection.  Could it be a jsp, I

 honestly don't know because I am not a java developer.





If anyone could help me or guide me through this process it would be greatly

 appreciated.

Hi,
 I tried that, and it did not help
it looks like maybe related to a subject of disabling WebDav from working with

though if webDav is working, it is strage because i deleted the WebDav

This is the crux of your problem right here.  =)

In my experience, getting multiple Java apps to behave in the same
container was a headache (even if the code was fine, but the apps just
needed their own space).


: questions:

You *might* be able to do this with a security policy, though I'm pretty
sure that's limited to actual access (file, port, etc).

It sounds like you're trying to solve a policy problem with technology.
You'd do well to nip this in the bud and contact the person(s)
responsible.

What are your options for setting up each app in its own container?
That won't prevent developers from making foolish mistakes, but it at
least gives you enough isolation to shutdown/restart the one container
with no effects to the others.


: notice:
: all this should be possible without "cooperative behavoiur" of the
: serlvet developer and so implememented completely transparent to them.

Is there any reason you can't confront the offending developer(s)?  If
this is a corporate situation, you could push this up the management
chain.  Statements such as "app A is adversely affecting apps B and C"
tend to make an impact. =)

If you're a host and these are your customers, I'm sure you can tell the
offender they risk account termination if they continue to impact your
other customers.  This could (should) fall under any terms of service to
which they agreed when they signed up...

controlling and limiting threads launched by servelts

[Romeo Benzoni]

Hi

situation:
A tomcat instance where several independent webapps are hosted. (kind of
"shared hosting").

scenario:
A developer for one of this webapp is kind of lazy (or not that skilful)
and launches a new thread during init(). but he does not terminates this
thread during the destroy() of the servlet.

effect:
so when he reloads his webapp the thread keeps on running. further more
his webapp could in "developing state" where this reload happen very
often. so after some time I've a lot of "orphaned" threads running in my
tomcat VM. When I notice this, or a Developer complains that something
must be wrong on my system as his thread behaves weired (most often
non-deterministic behaviour because of race conditions when more than
one of these threads are running) I send information about correct
launching and terminating threads from a servlet of course. But this
solution leaves a unpleasant feeling. further more I'll have to restart
tomcat to get rid of these threads. I would prefer a technical solution
which prevents this. I know that I can't isolate webapps 100% against
each other concerning system ressources (slugish servlet can allocate
too much memory and cause an OutOfMemoryError etc.). I did had a look a
java policy but you can't either prevent a thread from being started,
nor have any fine grained control on threads. non the less here are my 

questions:
is it possible to...

- prevent a serlvet from launching threads at all?
- limit the number of threads a webapp/servlet can launch
simultaneously?
- automatically terminates all threads a webapp/servlet has launched
when stopping context? (kind of GC for threads)

notice:
all this should be possible without "cooperative behavoiur" of the
serlvet developer and so implememented completely transparent to them.


is this possible at all?
any ideashow to implement?
thanks in advance
