please help its urgent for me

Hi -

You've got a library (.jar file) mismatch somewhere.

Here are a couple of examples, Googling for your particular error message:

STRONG SUGGESTIONS:
1. If you've got GJC Java ... then *uninstall* it

I strongly recommend you install only the Sun JDK (along with the corresponding Sun JRE); preferably 1.6 or higher.

2. Do a search-and-destroy mission for any old copies of servlet.jar or friends you might have on your system:
3. Carefully check your CLASSPATH, web.xml, IDE project settings and anything else that might be picking up old/incorrect library versions.

how do i install jdk with jre
they get installed as two separate folders
which path to i give for JAVA_HOME

JAVA_HOME most probably in /usr/java/jdk.version

hi paulsm4 suggested me to install JDK with jre how do i install it
when i install jdk the path is /usr/java/jdk1.6.0_20
and the path for jre is /usr/java/jre1.6.0_20
so how do i do this what will be the envireoment variable in this case

Pointing to the JDK should be sufficient.

I don't know your distro, but this link provides a lot of good information if you have any problems configuring Java itself:

http://www.cyberciti.biz/faq/howto-u...igure-jdk-jre/

And please don't forget the other steps I recommended:

2. Look for any old copies of servlet.jar or friends you might have on your system:

find / -name "servlet*jar" -print 2>/dev/null

3. Carefully check your CLASSPATH, web.xml, IDE project settings and anything else that might be picking up old/incorrect library versions.

still the same no change the Servlet Examples execute but not the jsp examples. also if i write my own jsp code for test it executes but not my main application which is also in java
th output of the command below
find / -name "servlet*jar" -print 2>/dev/null
/usr/share/java/servletapi5.jar
/usr/share/java/servlet.jar
/usr/local/tomcat/server/lib/servlets-webdav.jar

how do i know which are old

Hi -

1. You can figure out which files are which using "ls -l". Files in the same package will likely have the same dates; older files are from older libraries.

2. Q: did you look for GJC (a suggestion in my first post)?
Q: If you found it, did you uninstall it?

3. MOST IMPORTANT:
It sounds like some jsp's and/or servlets are working, and some aren't.
Q: Could you please be as specific as possible about what's working vs what's not? Post code, if at all possible.

Thank you in advance .. PSM

PS:
Please specify, too:
* Your distro and version
* Whether you got your Tomcat 5.5.28 from your distro's package manager, or whether you built it yourself

PPS:
It couldn't hurt to check your Tomcat log, if you haven't already. Here's an example from mine:

thanx a lot problem solved
it swas sumethign to do with my custom code if i remove it out from the webapps folder tomcat seems to be working fine will all inbuild exampples working
there was a bug in my application which was looping around causing the problem
thanx a lot
