You never encountered OutOfMemory exceptions? I had so much issues with JAVA memory management so now I'm so confuse with it that I gave up to understand very well how it is working, my only fear is OutOfMemory, if my webapp runs fine it's OK, I don't touch it.

RE: Over 1000 threads running in production
Chuck, Many thanks for your feeback. From: Guillaume Lahitette [mailto:[EMAIL PROTECTED] Subject: Over 1000 threads running in production Our operations team discovered over 1000 java threads running on each production server. It appears that about 20 threads are added to this count every hour. Since no one else seems to be reporting this kind of problem, odds are it's a bug in one or more of the applications you're running under Tomcat. This is what I am suspecting too. It's a large application with third party modules (open source, outsourced,...). I am not too sure on how to best track it down. Pointers welcome! There's an off chance it could be a problem in the JRE, since you're using a level that's been out of date and unsupported for quite some time. We'll try to run some tests with the latest 1.4.2 JDK...If performance increases, it will be an easy sell (although we'll want plenty of regression testing). If not, operation teams will argue about the upgrade cost, benefits The number of threads Tomcat uses to service requests is controlled by the maxProcessors parameter of the Connector element you're using; for 4.1, the default value is 20, and it would be very, very unusual to ever need to set it to much over 100. Since you don't seem to be aware of this configuration parameter, you're probably using the default. We're using the default values for TC4.1.26: minProcessors=5 maxProcessors=75. Other than a few created for internal purposes by Tomcat and the JVM itself, additional threads must come from the applications. How can I tell? Can I monitor who/when these are created? I would be highly suspicious of some piece of code kicking off a thread and then losing track of it and the thread not having any logic to terminate itself when it's no longer needed. Slightly off topic: a third party module uses RMI: would RMI kick off a new thread for each new RMI connection? We're suspecting this module does NOT release RMI connections correctly and would explain these accumulation of threads. I'm trying to get this confirmed... e.. Any known issues with our setup? Can't tell unless you pass on the .xml files. The server.xml is per default, except for port numbers. Any other relevant XML files? Tons of thanks for your feedback Chuck!

Problem with BASIC authentication

Trouble w/ remote debugging w/ Tomcat 5.5 and JDK 5.0
I found the FAQ (http://jakarta.apache.org/tomcat/faq/development.html) and followed the instructions there, including: added env variable JPDA_ADDRESS=8000 added env variable JPDA_TRANSPORT=dt_socket added -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n to java command line options, but my Tomcat still doesn't seem to be running with the debug port enabled. I can't connect via Eclipse, or even telnet to the port. I'm running on WinXP SP2 w/ Tomcat as a service. Here's a screenshot of the service config: http://images.fender.net/tomcat.png I'm guessing this is a really a JDK 1.5/5.0 issue and not a problem w/ Tomcat, but any help would be appreciated.

Servlet / Jini lookup
Hello,
I'm trying to contact a Jini lookup service (reggie) from a simple
servlet. I'm using Tomcat 5.5.7, Java 1.5.0_01, Jini 1.2.1 and Solaris8.
The problem is that, after the call to LookupDiscoveryManager() (see
source code below), the discovered() method is never called back.
Here is what I get in my browser after an exec :
before LookupDiscoveryManager
end
I have successfully run a similar code in a standalone Java app (i.e.
without Tomcat / servlet), and everything is OK.
In fact, I have no error message nor Exception thrown. :-( I simply
don't have any response from reggie.
Any help would be appreciate,
Olive

Re: new to tomcat 5.0.28-how i can add context in the server.xml

Thanks for the reply.
But if i see the manager.xml under this location it's contents are like this:

debug=0 privileged=true
!-- Link to the user database we will get roles from --
ResourceLink name=users global=UserDatabase

So for my webApp viz. reports if i put this kind of contents:
Context path=/reports docBase=C:\talkBack src\talkback\java\build\reports
debug=0 privileged=true
/Context
and then i restart the tomcat i see the directory listing.
Shud i giv refrence of build dir or src directory. Actually my
build.xml compiles everythign from my src to corresponding build Dir.

You have to give a docBase that points to your webapps, in your
example you must have this directory :
C:\talkBack src\talkback\java\build\reports\WEB-INF
and I hope a web.xml inside.
and for java classes (your build dest must be something like this)
C:\talkBack src\talkback\java\build\reports\WEB-INF\classes\
Your JSPs can be everywhere inside (depends on you web.xml):
C:\talkBack src\talkback\java\build\reports\
Don't forget to specify welcome-file in your web.xml.
You removed the RessourceLink to user databases so why do you continue to
use privileged=true ? I don't know if it's correct...
You can add log info to your context that might help you later:
Logger className=org.apache.catalina.logger.FileLogger
prefix=localhost_reports_log. suffix=.txt
timestamp=true/
Good luck,
David.
PS. I don't know if the '\' is OK for file separator inside this file:
you'd better use '/'
like this: c:/webapps/reports.

Hi, Tomcat won't know anything about your Thread just because you created it in init(). Tomcat does not monitor your threads, you need to manage them yourself if you insist on creating them which many will tell you is naughty. Maybe you can kill your Thread in the destroy() method of the same servlet, since it sounds like you may have a class member reference to your thread in there.

Here's what I've done to generate all the appropriate files (parts coped from other posts to this list): # Create a private key and certificate request openssl req -new -subj /C=US/ST=North Carolina/L=Raleigh/CN=akuma-c -newkey rsa:1024 -nodes -out ca.csr -keyout ca.key # Create CA's self-signed certificate openssl x509 -trustout -signkey ca.key -days 365 -req -in ca.csr -out ca.pem # Copy ca.pem to ca.crt, edit and change TRUSTED CERTIFICATE to CERTIFICATE # import ca.crt into the Trusted Root Certificates Store in IE #Import the CA certificate into the JDK certificate authorities keystore: keytool -import -keystore %JAVA_HOME%/jre/lib/security/cacerts -file ca.pem -alias my_ca_alias -keypass changeit -storepass changeit # Create a file to hold CA's serial numbers. echo 02 ca.srl # Create a keystore for the web server. keytool -genkey -alias tomcat-sv -dname CN=akuma-c, OU=RD, O=MyOrganization, L=Raleigh, S=North Carolina, C=US -keyalg RSA -keypass changeit -storepass changeit -keysize 1024 -keystore server.keystore -storetype JKS # Create a certificate request for the web server: keytool -certreq -keyalg RSA -alias tomcat-sv -file server.csr -keystore server.keystore -storepass changeit # Sign the certificate request: openssl x509 -CA ca.pem -CAkey ca.key -CAserial ca.srl -req -in server.csr -out server.crt -days 365 # Import the signed server certificate into the server keystore: keytool -import -alias tomcat-sv -keystore server.keystore -trustcacerts -file server.crt -storepass changeit # Import the CA certificate into the server keystore: keytool -import -alias my_ca_alias -keystore server.keystore -trustcacerts -file ca.pem -keypass changeit # Create a client certificate request: openssl req -new -newkey rsa:512 -nodes -out client1.req -keyout client1.key # Sign the client certificate. openssl x509 -CA ca.pem -CAkey ca.key -CAserial ca.srl -req -in client1.req -out client1.pem -days 365 # Generate a PKCS12 file containing client key and client certificate. openssl pkcs12 -export -clcerts -in client1.pem -inkey client1.key -out client1.p12 -name Client # Import the PKCS12 file into the web browser under Personal Certificates # edit the server.xml file and set clientAuth=true and keystoreFile to point to my server.keystore file.

Access denied with Apache + Tomcat config
Hello All,
I have searched the archives but have been unable to find a solution
to my problem.
I am integrating Apache 2.0.52 with Tomcat 5.0.28 using mod_jk 1.2.8
(compiled from source). My client wants to continue using Apache as
the web server due to security and ease of configuration issues, so
using Tomcat as the web server is *not* an option.
The configuration appears to be good, and I can load a page such as
loading {server}/servelets-examples. However I get 500 Interal
Server Error whenever I try to launch any of the jsp files. There is
no indication of error in the CATALINA/logs files. The only
indication in the Apache log files (error_log) occurs when attempting
to load the initial index.jsp page of a context:
[Tue Mar 15 16:10:23 2005] [error] [client xxx.xxx.xxx.xxx] client
denied by server configuration: index.jsp
I have checked my httpd.conf file and the
CATALINA/conf/auto/mod_jk.conf file but can find no reason why access
to the *jsp is denied.
I can include full versions of my various files, but for the sake of
space I'm only going to include snippets here:
[Apache httpd.conf]
LoadModule jk_module modules/mod_jk.so
...
Include /usr/local/tomcat/conf/auto/mod_jk.conf

Re: Failing a JK Worker thread
I didn't hear back from any one so I looked through the code. I
couldn't find any sign of code that would provide this functionality,
so I added the following before line 605 of jk_ajp_common.c. I
recompiled and it seems to be working as intended so far.
if (d-status=500) {
jk_log(l, JK_LOG_ERROR,
Tomcat server returned status=%d,d-status);
JK_TRACE_EXIT(l);
return JK_FALSE;
}
I may end up using a case statement and preventing apache from trying
the next worker on bad request or something like that. Hope this helps
some one else too.

Re: Access denied with Apache + Tomcat config
All, I believe that I found my problem, and for the sake of posterity I'm posting it for the next poor fool who is forced to chase around the web and through books looking for decent documentation. When I set up Tomcat I copied the sample workers.properties file from the JK source. However it turns out that the sample file uses the wrong worker name (compared to the name that is automatically generated.) In my case, the sample file was this: worker.list=ajp13w worker.ajp13w.type=ajp13 worker.ajp13w.host=localhost worker.ajp13w.port=8009 However, as can be seen in my original post, the conf/auto/mod_jk.conf file wants to use ajp13. By changing the workers.properties file to 'ajp13' and NOT 'ajp13w' everything started working.

Yes, that is the problem, and that is why it wasn't implemented.
In case your application returns 500, then entire worker is marked
in error state and is unusable for consecutive requests until
recycled.
The solution would be to mark the url in error state, add url cache, and
then recycle the context path, but this would require lots of work,
add more complexity, with dubious usage.
I would suggest that you rewrite your application to offer high
availability. It would be much smarter then doing HTTP 500 tricks.

Mladen.

RE: {OT] Re: Jumping in and out of JSP
I am using a template.jsp file that calls a function defined in another
file. Then every file, ie index.jsp, in the site defines that function
and includes the template which calls the function. That way I only
have one file defining what the site looks like.
Is there a better way to template a site. I don't like the method of
including sections into each jsp file. This makes adding new sections
to every page difficult.

Jk1 jkstatus?
So with JK 1.2.8, is there any equivilent method of finding the data in the jkstatus scoreboard from mod_jk2?? I understand jk2 is no longer the choice module for Apache 2.0.x. Funny, when we first upgraded to Apache 2, the official line was that mod_jk1 should not be used with Apache 2, and we needed to get with the program and move to the refactored jk2- once we did, jk2 was no longer supported and considered flaky- meanwhile on the Apache 2 developers list there continues to be threads asking why people still use Apache 1.3 and aren't upgrading to 2.0, or may even be downgrading in some cases from 2 back to 1.3- I think its partly because things like the jkX confusion. So now we are running on an unsupported platform where at any time a patch could create problems with mod_jk2 with no resolution except to fix it ourselves, and sure ajp13_proxy is coming, but we won't be first in line with apache 2.2 after playing musical chairs with jk1/jk2. So what other things besides the scoreboard will I have to live without when downgrading back to JK1?

RE: Tomcat 5.5.7+JRockit = windows service won't start
From: Caldarale, Charles R [EMAIL PROTECTED] By definition _all_ -X parameters are non-standard, but there are quite a few you simply can't avoid using (-Xmx being the obvious example). It would seem like JRockit took the wrong turn here, since -Xrs has been used to reduce JVM signal usage for many, many years. As someone else suggested, why don't you simply edit the registry entry generated by the installer and change the -Xrs to -Xnohup? I acknowledge that all -X parameters are non-standard and would agree that JRockit seems to have made an odd choice in not supporting -Xrs. But having said that, I still think it should have remained a parameter to be explicitly set when calling the installer (seems to have changed to hard-coded around 5.0.22 or so?). With regards to the registry, the installer does not appear to create an entry that explicitly defines the -Xrs parameter. If it did it would be an easy change as has been suggested. The ...ParametersJavaOptions entry defines the various -D parameters being used but does not define -Xrs. I tried adding -Xnohup to this entry but no change in results.

Tomcat 5.028 with Apache 2.053 on different machines
Hi
I'm trying to setup Apache 2.053 on one machine, and Tomcat 5.028 on another.
I've put mod_jk.so in my modules directory. Configured bother the httpd.conf
and the workers.properties file on the apache machine.
Here are the lines
httpd.conf
LoadModule jk_modulemodules/mod_jk.so
JkWorkersFile/httpd/conf/workers.properties
JkLogFile /httpd/logs/mod_jk.log
JkLogLevel info
JkLogStampFormat[%a %b %d %H:%M:%S %Y]
JkOptions +ForwardKeySize +ForwardURICompat
-ForwardDirectories
JkRequestLogFormat %w %V %T
JkMount /shopping/*worker1
worker.properties
worker.list=worker1
worker.worker1.type=ajp13
worker.worker1.host={tomcat machine hostname} --- edited for privacy.
worker.worker1.port=8009
worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.recycle_timeout=300
The server.xml file is already set to listen on port 8009
Connector port=8009
enableLookups=false redirectPort=8443 debug=0
protocol=AJP/1.3 /
As far as I know those are the only 2 items you need, but when I try to call
anything from apache with the context /shopping ie
http://{host}/shopping/index.jsp it tries to finding /shopping on the apache
machine. It's like it hasn't mounted the directory. Do the web apps have to
be on the apache machine? I would like to keep all the Tomcat stuff on that
machine, and away from the apache box.
The mod_jk.log file has this line in it.
[Tue Mar 15 02:23:33 2005] [info] jk_handler::mod_jk.c (1883): Could not find
a worker for worker name=worker1
there is no error in the error_log file
and access_log has this
GET /shopping/index.jsp HTTP/1.1 500 648
Am I missing something?

RE: {OT] Re: Jumping in and out of JSP
So, if I understood your requirement correctly, you want to execute a
single file, I,e JSP for every request. Probably after processing a
request you might wish to set an attribute to identify the response
view.
I would suggest to use standard jsp include tag, with this your template
JSP would look like
%-- put all your html/jsp code here (like the header, pictures
etc.)--%
jsp:include page=%=request.getParameter(mainPage)% /
%-- put all your html/jsp code here (like the footer etc.)--%
Keep in mind that this has a performance issue, as every request results
in runtime inclusion of output from the included JSP.
Hope I was of some help.

I am using a template.jsp file that calls a function defined in another

and includes the template which calls the function. That way I only
have one file defining what the site looks like.
Is there a better way to template a site. I don't like the method of
including sections into each jsp file. This makes adding new sections
to every page difficult.

Yes it is and one of the reaons using JSP's instead of just Servlets

RE: Tomcat 5.5.7+JRockit = windows service won't start
From: BB Commish [mailto:[EMAIL PROTECTED] Subject: RE: Tomcat 5.5.7+JRockit = windows service won't start With regards to the registry, the installer does not appear to create an entry that explicitly defines the -Xrs parameter. That's odd, since the -Xrs is in my registry entry, albeit this is with an older Tomcat level. It's at the end of the parameter string, and normally won't display in regedit unless you've got a really wide screen or use the Modify menu.

Re: Jk1 jkstatus?
Good afternoon Byron. There is a way in JK to check the status of your workers and even configure them to some degree. It requires pretty much the same setup as in JK2; for details about this and other VERY useful info on putting Apache and Tomcat together see this webinar: https://jboss.webex.com/jboss/onstage/tool/record/viewrecording1.php?EventID=136098785.

So with JK 1.2.8, is there any equivilent method of finding the data in the jkstatus scoreboard from mod_jk2?? I understand jk2 is no longer the choice module for Apache 2.0.x. Funny, when we first upgraded to Apache 2, the official line was that mod_jk1 should not be used with Apache 2, and we needed to get with the program and move to the refactored jk2- once we did, jk2 was no longer supported and considered flaky- meanwhile on the Apache 2 developers list there continues to be threads asking why people still use Apache 1.3 and aren't upgrading to 2.0, or may even be downgrading in some cases from 2 back to 1.3- I think its partly because things like the jkX confusion. So now we are running on an unsupported platform where at any time a patch could create problems with mod_jk2 with no resolution except to fix it ourselves, and sure ajp13_proxy is coming, but we won't be first in line with apache 2.2 after playing musical chairs with jk1/jk2. So what other things besides the scoreboard will I have to live without when downgrading back to JK1?

Re: Failing a JK Worker thread
We have an application running as a webapp which requires legacy
systems and network resources which are not fault-tolerant. Luckily
these resources are stateless. So we have replicated these resources so
that one is available per tomcat instance. When we attempt to use one
of these resources from within the webapp and it fails, we need a way
to try the next pair (tomcat legacy) in the group. This will allow
us to provide a balanced fault-tolerant service with a webapp
interface. Since the tomcat instance is responding and functioning,
the reply_timeout was not met so apache webserver considered the
request a success. Providing a application error from tomcat (maybe a
503 or 401 instead of 500) seemed like the rightest way to do it.
I see a few other options:
1. Put a layer on top of apache that tests the response and makes a new
request. This doesn't buy us anything and circumvents the use of jk
2. (some how/maigcally) Send an out of process message from tomcat back
to apache that the resource is down.
3. Modify AJP to handle this error (this may already have a mechanism
that I missed)
Does any one have any other suggestions for ensuring reliability when
there is a 3rd party piece of hardware/software which your webapp
relies on that has no fault-tolerance of its own?
Thanks for any suggestions,
Dan

I didn't hear back from any one so I looked through the code. I couldn't
find any sign of code that would provide this functionality, so I added
the following before line 605 of jk_ajp_common.c. I recompiled and it
seems to be working as intended so far.
if (d-status=500) {
jk_log(l, JK_LOG_ERROR,
Tomcat server returned status=%d,d-status);
JK_TRACE_EXIT(l);
return JK_FALSE;

I may end up using a case statement and preventing apache from trying
the next worker on bad request or something like that. Hope this helps
some one else too.

Is there any way from within the webapp that is being contacted to
induce a failure other than not returning before the reply_timeout? For
instance, can you return an HTTP error message from tomcat that would
cause web server to retry the request to the next worker in the group

Installation Issues - AIX 5.2
I've attempted to install tomcat 5.0.28 from source on an AIX 5.2 system without internet access. When running ant, cvs fails. So I downloaded and installed the binaries, but I get http 500 errors when running a javascript for secure login. The vendor supplying the script feels that tomcat does not know anything about the jdk (1.4.2) installed, despite JAVA_HOME being defined. I'd prefer to build from the source files (to resolve any issues from the binaries being built elsewhere), but I can't get past the errors... I'm trying to do all of this remotely through a VPN, which unfortunately won't let me connect at this time to acquire the output from ant. I'll post that tomorrow, assuming I get connected. Does anyone have any ideas, despite the sketchy details that I have provided? Regards, Bob Wyatt - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
SSL Appliance and Tomcat5.0.30/CoyoteConnector
We employ an SSL appliance in front of servers running Tomcat5 stand-alone and wish to configure the CoyoteConnector as we have done previously with Tomcat4: Connector className=org.apache.coyote.tomcat5.CoyoteConnector port=8543 minProcessors=16 maxProcessors=384 enableLookups=false acceptCount=128 debug=0 connectionTimeout=30 scheme=https secure=true disableUploadTimeout=true proxyName=localhost proxyPort=443/ However, since secure=true is being specified, Http11Protocol.checkSocketfactory() in Tomcat 5.0.30 is attempting to create a secure SSL ServerSocketFactory. Of course, this fails since other SSL configuration parameters are not present. Since we are behind and SSL appliance, we really want just an ordinary ServerSocketFactory to be used and request.isSecure() to return true within our web applications. As I noted above, a similar configuration used to work for us on Tomcat 4.1. Short of implementing a custom SSLImplementation and configuring it using an imbedded Factory/ tag within the Connector definition, is there any way to force Tomcat 5.0/Http11Protocol to use a default ServerSocketFactory?

Strange Tomcat Error
Hi all, Recently I lost the hard drive on one of my production tomcat servers. I've since reinstalled and setup the effected machine to mirror the configuration of one of my other servers that I know to be working fine. I know for a fact that my servlet code is fine and that the tomcat configuration I'm using is valid as both were copied from another running server. However despite its identical configuration, the repaired machine now freezes somewhere between querying the database for data and the XSL transformation of the XML generated by my servlets. No error messages are written to catalina.out, the terminal or localhost.log and the server is unable to process additional requests after this happens. Additionally, following the error tomcat will not respond to the execution of shutdown.sh and it seems the only way I can abort the process is by issuing a kill -9 command to the process number of tomcat's jvm. Has anyone ever experienced anything like this before? And if so what did you do to fix it. Here's some information on my execution environment: OS: Redhat Linux 9 Kernel: i686 2.4.20-28.9smp Tomcat: 5.0.28 Database: Oracle 9i JVM: 1.5.0_01 Thanks, Larry - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
