Hi -

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

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

http://www.myeclipseide.com/PNphpBB2...ic-t-6369.html

http://software.itags.org/apache/55829/

http://lists.apple.com/archives/Java.../msg00254.html

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:
Quote:
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.

'Hope that helps .. PSM

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.

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:
Quote:
cd /var/log/tomcat5
less catalina.out =>
Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
Using JRE_HOME:
...
INFO: Find registry server-registry.xml at classpath resource
25-Apr-10 3:06:31 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 15167 ms
