load balance with tomcat
We're trying to install our existing web app on multiple machines and put a BigIP load balancer in front of them. Do we need to do anything different with Tomcat and/or our web app to get this load balancing to work, or should we basically be able to copy the Tomcat directory onto each machine and go? The reason I ask is because if we access each web server directly via a public IP address, we can use the web app. However, if we try to go through the BigIP's public address, it won't work (and we're trying to figure out why). We're using Tomcat 4. Thanks for any tips... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Configuration: jk 1.2 apache 1.3 workers and virtual hosts
Hello, since the documentation is not explicit about this, maybe someone on this list can help me. configuration: linux tomcat 5.0 jk 1.2 apache 1.3 I have several virtual hosts running on my system. Does that mean that I have to create a separate worker for each virtual host? e.g. worker.list=virtHost1,virtHost2,virtHost3 # host1 worker.virtHost1.type=ajp13 worker.virtHost1.host=www.virtHost1.com worker.virtHost1.port=8009 # host2 worker.virtHost2.type=ajp13 worker.virtHost2.host=www.virtHost2.com worker.virtHost2.port=8009 # host3 worker.virtHost3.type=ajp13 worker.virtHost3.host=www.virtHost3.com worker.virtHost3.port=8009 Sorry, I wouldn't ask that that question if I had found any documentation on virtual hosts and jk 1.2 Any help or hint is very much appreciated Michael Kastner - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Session restart replication when using jsvc
Hi all! I recently switched from using Tomcat 5.0.28/jk2/Apache2 to running tomcat standalone using jsvc. This works great for me except for one thing; Sessions are not replicated when I restart tomcat. To stop Tomcat I'm using 'kill -9 `cat /var/run/jsvc.pid`'. When Tomcat is stopped this way the StandardManager does not serialize the sessions to SESSIONS.ser. Can I stop Tomcat in another way, to make it serialize the sessions?

Issues with Tomcat on AIX?

Has anyone done this migration? If not, does anyone run Tomcat on AIX 5.2

If you do, do you use Java Security (-security on startup)? I am having an

adding the pertinent grant statement but it does not work on the AIX

added this grant statement:
grant codeBase file:${catalina.home}/server/- {
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.util.ParameterMap;

This statement fixes the problem using Solaris and Sun's JDK 1.3. It does
NOT fix the issue in the following IBM JDK:

WebDAV and redirects
I've been struggling with the whole issue of Microsoft WebDAV clients failing to including a trailing slash in collection URIs even when I ask nicely. It looks like I can fix this with redirects, but that opens up another can of worms: the Microsoft client redirect bug. I'm trying to get the last word on this, and it looks like Mark Thomas or others may be able to set the record straight. http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]msgId=2007923 Basically, Microsoft clients will issue a PROPFIND for http://www.example.com/folder instead of http://www.example.com/folder/ , even though the latter is the true name of the collection and the former is a file that doesn't exist. WebDAV servers get around this by issuing a redirect from http://www.example.com/folder to http://www.example.com/folder/ . It appears that some Microsoft WebFolder implementations will follow up the redirect with a GET instead of a PROPFIND, breaking WebDAV access. For this reason Apache has a redirect-carefully option for user agents such as Microsoft Data Access Internet Publishing Provider. So here are my questions: * What's the most appropriate redirect to send to redirect from http://www.example.com/folder to http://www.example.com/folder/ ? A 301 (permanent) or 302 (temporary)? Which does Apache do? Which does the Tomcat WebDAV servlet do? * For those clients that do not follow redirects properly, what should be done as a workaround? Should the server simply act as if http://www.example.com/folder/ were requested when http://www.example.com/folder is requested, if the user agent is one of those recognized as buggy? Is this what Apache does for redirect-carefully? What does the Tomcat WebDAV servlet do? * Currently, in my implementation I'm sending back a 302 redirect, and Microsoft WebFolders handles it fine on Windows XP Professional SP2. But is it true that other versions do not follow redirects? As all versions send the same user agent identification (Microsoft Data Access Internet Publishing Provider), what should the WebDAV server do---implement the redirect-carefully hack even with those clients that properly follow redirects, as the server can't tell the difference? What does the Tomcat WebDAV servlet do? A lot of this information seems to be on the Internet, but as little pieces scattered about.

Re: Issues with Tomcat on AIX?
I had not checked that, although it is true that the JDK was installed
under the same user (well, now it is; I was using the AIX installed 1.3.1
smit pkg but I since coped it to a work directory). I do not see WHY the
owner of the JDK has to be the the same user as the Tomcat PID owner. I
can see why it would need read access. To be sure, I chmod'd everything to
755/644 to make sure. Still no dice.
I tried to setup another app that uses the same base policy and the error
did not arise. Others did but I was able to write in policy changes that
got rid of them.
Man, this is frustrating.
Ben Ricker
You probably did this alread, but might want to check the access
permissions for all directories and files involved. That stuff gets
messed up pretty easy. The user that Tomcat runs under should be the
same user that the JDK was installed with... Might be a complicating
factor??
[EMAIL PROTECTED] 12-29-2004 09:51
I am migrating a dozen apps from Solaris and Tomcat 4.0.6 to AIX 5.2
and
Tomcat 4.0.6.
Has anyone done this migration? If not, does anyone run Tomcat on AIX
5.2
( I would assume so)? Do you use IBMs JDK? I am using the 1.3, 64-bit
J2SDK.
If you do, do you use Java Security (-security on startup)? I am having
an
issue with an security exception being thrown. I can fix the exception
by
adding the pertinent grant statement but it does not work on the AIX
version (it does work on Solaris!)?
Here is the error:
Security Violation, attempt to use Restricted Class:
org.apache.catalina.util.ParameterMap
java.security.AccessControlException: access denied
(java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.util)
I pinpointed the class in the error msg as being in the server dir. So
I
added this grant statement:
grant codeBase file:${catalina.home}/server/- {
permission java.lang.RuntimePermission
accessClassInPackage.org.apache.catalina.util.ParameterMap;
};
This statement fixes the problem using Solaris and Sun's JDK 1.3. It
does
NOT fix the issue in the following IBM JDK:
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1)
Classic VM (build 1.3.1, J2RE 1.3.1 IBM AIX 5L for PowerPC (64 bit
JVM)
build caix641311-20011123a (JIT enabled: jitc))
Any ideas?

FW: j2sdk problems
Can anyone help me on this issue please? I have reviewed the log files to no end on this issue. I see nothing at all in terms of errors. The problem is we are running jboss-3.2.5 in conjunction with j2sdk-1.4.1_04 on a Red Hat Linux 9 system with the 2.4.20-31.9smp kernel and I have had to restart the jboss services. I have reviewed the /var/log/messages file found nothing in reference to jboss or mod_jk2 or j2sdk. I reviewed the error_log file for the website under its configuration and found no errors pointing towards mod_jk2, however there were references to errors involving re-initializing of SSL, Directory index forbidden by rule: ~/public_html (where tilde is the homedir for the site) I also went to look at the /var/log/httpd/mod_jk.log file and there is nothing in it, however, there was a previous log file from over a week ago (since I rebooted the server and restarted the service last week).

Hmmm. Here is the source code of the jsvc-unix.c which is called upon a
signal.
static void handler(int sig) {
switch (sig) {
case SIGTERM: {
log_debug(Caught SIGTERM: Scheduling a shutdown);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
}
if (handler_trm!=NULL) (*handler_trm)(sig);
break;
}
case SIGINT: {
log_debug(Caught SIGINT: Scheduling a shutdown);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
}
if (handler_int!=NULL) (*handler_int)(sig);
break;
}
case SIGHUP: {
log_debug(Caught SIGHUP: Scheduling a reload);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
doreload=true;
}
if (handler_hup!=NULL) (*handler_hup)(sig);
break;
}
default: {
log_debug(Caught unknown signal %d,sig);
break;
}
}
}
So, from the text I would assume SIGINT and SIGTERM should perform the
same shutdown behavior, but you can try to use
kill -s SIGTERM pid
or
kill -s SIGINT pid
and see what results you get. If it isn't behaving correctly then you
need to maybe
1) You might want to make sure you don't have the serialization of
session turned off some how...is it behaving correctly if you don't use
jsvc?
2) You are using the right tomcat class to start it up...surely or you
should get an errorI would imagine anywaysso maybe forget
this altogether.
3) You might want to search the tomcat source code for the Daemon
implementer class and locate the method stop to see if you can figure
out if it is being called. It should be I would imagine since tomcat is
stopping, but if it is not, then I guess it's a Daemon/jsvc error and
you need to talk to that list. On another note same subject.You can
look in the daemon src at the file /src/native/unix/native/java.c and
you could put some code into the java_stop function to see if you can
figure out if the function is going to call (through jni) the Daemon
stop method correctly or not. REMEMBER: The Daemon startup code does
not force the class used as a Daemon to actually implemnt the interface
through source code, but the class can simply have the correct
methods.only know this because of the source code not any
docsdon't know if Tomcat does this or not.
4) You might look in your jsvc error file...where ever you have put it
and look for the text 'Cannot stop daemon' or 'Cannot found Daemon
Loader stop entry point'that mis type of Cannot foundis really
in the logging of the 1.0 release source code. Because even though you
get this text and tomcat goes awaythe method to stop may not have
been found and the jsvc process is going to kill the JVM anyways.
Hope some of that helps

RE: FW: j2sdk problems
Again you are unclear. What do you mean by fail? The JBoss process? If you mean that, then you are on the wrong list. This is for tomcat users, not JBoss users. Here is what I would do: 1) If you are having process problems with Jboss, contact a JBoss related list. 2) If you cannot get access to go from mod_jk to JBoss, check the access logs. What is the return code for the app? Is it something outside of 200-300? Is there an error given to a user, i.e., on their screen? Try bumping up the logging levels to debug in the mod_jk config. These are common troubleshooting techniques. You might want to Google for 'Apache troubleshooting' to get some tips.

Hi Sweta. I assume you mean increase the stack size available to each thread. From http://blogs.sun.com/roller/resources/watt/jvm-options-list.html, which is a giant list of JVM options: -Xsssize - size - set maximum native stack size for any thread Also do a 'ulimit -a' to determine what your process constraints are on stack size; if you increase the stack size using the -Xss option but don't give your process permission to use that extra stack size you will get exceptions as well.

Re: Changing Stack Size in Tomcat 4.130
Keep in mind that I believe increasing the stack size too large can have performance implications. If I understand correctly each thread has a stack that stores process information so that as threads context switch in and out this information gets copied into and out of memory; if you increase the stack size more memory will have to get copied in and out, slowing down performance. Can folks correct me on this if I am wrong? Is this a correct understanding of the stack? Would this be a true bottleneck for performance? Thanks, Brad At 01:41 PM 12/29/2004, you wrote: Hi Sweta.

Tomcat is version 5.0.30, originally I just copied from a blank struts app set of files, which used the 2.2 DTD. Regardless of which DTD's tomcat supports under 5.0, it seems to be a bug that it ignores the stated DTD and gives no error or warning that a tag is being used that the DTD does not know anything about. Now if a DTD version stated in the web.xml file is not supported by tomcat, I'd expect an error be generated there as well. I think you have to set validating to true in server.xml.

Apache and Tomcat VirtualHost Config Problem
Hi, 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. I want Apache httpd to serve static files and Tomcat to serve dynamic files (ex. jsp's). This all works fine if I have all dynamic files located on the url as www.mysite.com/home/file.jsp However, I cannot seem to get the dynamic files to work properly if I want them to be at the same location on the url as the static files so that www.mysite.com/file.jsp (served by Tomcat as requested by Apache httpd) and www.mysite.com/index.htm (served by Apache httpd) coexist without any problems. I did come up with a config that works partially for jsps at www.mysite.com/file.jsp but there are some problems. This is the main problem: Eventhough I am able to access all the jsp page inside CATALINA_HOME/webapp/home, I am no longer able to access any jsp page inside other directory such as CATALINA_HOME/webapp/sample directory. I have included all relevant config settings below this paragraph. What can I do diffrently so that Apache can make a direct request to both CATALINA_HOME/webapp/home and CATALINA_HOME/webapp/sample instead of just one? It seems to me that with my original setting (above mentioned as www.mysite.com/home/file.jsp), requests from Apache will start from CATALINA_HOME/webapp and start going through different directory and display it through the url each time it enter a subdirectory. However, with my current setting, instead of starting at CATALINA_HOME/webapp, I just start at CATALINA_HOME/webapp/home, so eventhough I make a request from www.mysite.com, home does not show up anymore, but that also makes it impossible to access files from a directory such as CATALINA_HOME/webapp/sample. What kind of configuration do I need to make Apache access a jsp page from Tomcat without showing up a long url path but instead just something like www.mysite.com/file.jsp no matter which folder the jsp page is located inside tomcat? Here are the relevant config lines: --- 1)Inside server.xml, I enter the following: Host name=www.home.net debug=0 appBase=/opt/jakarta-tomcat-5.0.28/webapps/home unpackWARs=true autoDeploy=true Aliaslocalhost/Alias Aliaswww/Alias Alias10.0.0.10/Alias Context path= docBase= debug=1/ Valve className=org.apache.catalina.valves.AccessLogValve directory=logs prefix=home_access_log. suffix=.txt pattern=common resolveHosts=false/ /Host Host name=www.root.net debug=0 appBase=/opt/jakarta-tomcat-5.0.28/webapps/sample unpackWARs=true autoDeploy=true Context path= docBase= debug=1/ Valve className=org.apache.catalina.valves.AccessLogValve directory=logs prefix=cust2_log. suffix=.txt pattern=common resolveHosts=false/ /Host 2) Inside worker2.properties, I include the following: uri:www.home.net/*.jsp] worker=ajp13:localhost:8009 [uri:www.sample.net/*.jsp] worker=ajp13:localhost:8009 3) Inside httpd.conf, I include the following: VirtualHost 10.0.0.10:80 DocumentRoot /usr/local/httpd-2.0.52/htdocs/www.mysite.com ServerName www.mysite.com Location /*.jsp JkUriSet worker ajp13:localhost:8009 /Location /VirtualHost --- If anybody knows of a great source of documentation on this I would like to know.

tomcat error page
When there is an error in our web application, Tomcat will produce and error page that list down all the Exception stack trace and also THe version of the Apache Tomcat.

Re: Session restart replication when using jsvc
This is the old, buggy, code that ships with Tomcat. You need to get the
code from commons-daemon CVS HEAD if you want shutdowns (and restarts) to
work properly.

Hi Wolfgang!
by using signal 9 you give Tomcat no chance to perform any further
action. Maybe you omit -9 from your kill command.
Thanks for the tip. Tried it, but same results.

Hmmm. Here is the source code of the jsvc-unix.c which is called upon a
signal.
static void handler(int sig) {
switch (sig) {
case SIGTERM: {
log_debug(Caught SIGTERM: Scheduling a shutdown);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
}
if (handler_trm!=NULL) (*handler_trm)(sig);
break;
}
case SIGINT: {
log_debug(Caught SIGINT: Scheduling a shutdown);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
}
if (handler_int!=NULL) (*handler_int)(sig);
break;
}
case SIGHUP: {
log_debug(Caught SIGHUP: Scheduling a reload);
if (stopping==true) {
log_error(Shutdown or reload already scheduled);
} else {
stopping=true;
doreload=true;
}
if (handler_hup!=NULL) (*handler_hup)(sig);
break;
}
default: {
log_debug(Caught unknown signal %d,sig);
break;
}
}
}
So, from the text I would assume SIGINT and SIGTERM should perform the
same shutdown behavior, but you can try to use
kill -s SIGTERM pid
or
kill -s SIGINT pid
and see what results you get. If it isn't behaving correctly then you
need to maybe
1) You might want to make sure you don't have the serialization of session
turned off some how...is it behaving correctly if you don't use jsvc?
2) You are using the right tomcat class to start it up...surely or you
should get an errorI would imagine anywaysso maybe forget
this altogether.
3) You might want to search the tomcat source code for the Daemon
implementer class and locate the method stop to see if you can figure out
if it is being called. It should be I would imagine since tomcat is
stopping, but if it is not, then I guess it's a Daemon/jsvc error and you
need to talk to that list. On another note same subject.You can look
in the daemon src at the file /src/native/unix/native/java.c and you
could put some code into the java_stop function to see if you can figure
out if the function is going to call (through jni) the Daemon stop method
correctly or not. REMEMBER: The Daemon startup code does not force the
class used as a Daemon to actually implemnt the interface through source
code, but the class can simply have the correct methods.only know this
because of the source code not any docsdon't know if Tomcat does this
or not.
4) You might look in your jsvc error file...where ever you have put it and
look for the text 'Cannot stop daemon' or 'Cannot found Daemon Loader
stop entry point'that mis type of Cannot foundis really in the
logging of the 1.0 release source code. Because even though you get this
text and tomcat goes awaythe method to stop may not have been found
and the jsvc process is going to kill the JVM anyways.
Hope some of that helps

Servletexception from nowhere :/
Best groupmember,
I use the CommonFileUpload package to handle file uploads. I am trying to
get it to work by using the first basic method (from a user-tutorial). The
servlets compiles correctly in Eclipse, and I have all the libs at the
correct places. Servlet-api.jar and jsp-api.jar is in the classpath.
Common-fileupload.jar is in the WEB-INF/lib folder. This snippet throws an
ServletExeption:
public void doPost (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
if(FileUpload.isMultipartContent(request)) {
out.println(Ok, there is a multipart content...);
} else {
out.println(No multipart content...);
}
}
In the Commons mailinglist they said that it is not a problem with
Commonfileupload, but all other Servlets I have created works just fine.
The full message is:
javax.servlet.ServletException: Invoker service() exception
