Invalid Jar Index : Java 6/tomcat 5.5/linux
Hi,
I am sending this error again with more details:
I am currently using Java 6 and tomcat 5.5 and my environment is linux. I see an mysterious exception when I try to access a simple jsp page after tomcat is started. When I added a new maven project (which in turn will create a new jar) I see the exception when i am trying to access an simple index.jsp. When I name the project and jar as mhs-beacon-agent I see the following error and when the project is renamed as mhs-sample-agent I don't see this error. We also set up remote debugging in linux and see the exception is happening when it is trying to look up for "javax/servlet" , since sun.misc.URLClassPath is suns own proprietary code i am not able to debug the code. When I extracted two jar file and did an folder / folder comparison I don't see any differences in index.list file or manifest.mf apart from the name differences. I am seeing this exception only in linux environment and not on mac (which is my developer environment)Any help is greatly appreciated. Thanks !!

Sounds like your JAR might be corrupted. If this is a custom JAR, rebuild it. If it's a dependency you've downloaded with Maven, you might try clearing out the folders for the problem JAR(s) under "~/.m2/repository" and rebuilding. If a JAR downloaded by Maven is corrupted, the corrupted file it will sit on your local HD forever and cause problems. Manually deleting the Maven folders for the JAR usually clears up the problem.
Other thought. Upgrade your JVM. If it's as old as your Tomcat version, you could be simply hitting a bug.

You are about to hear this from every reply: upgrade. Tomcat 5.5 is no
longer supported. I am unaware of any critical security issues in
Tomcat 5.5.latest, but if any are identified, they will not be fixed.
You should upgrade as soon as possible to Tomcat 7.0. Most webapps
should have no trouble running with the new version of Tomcat, as the
servlet spec is supposed to be (mostly) backward-compatible. Newer
versions of Tomcat are more strict with a lot of spec concepts,
though, so you may have to make some modifications in order to upgrade.
But you really need to do it ASAP.

Looks like a damaged JAR file. What happens if you try this from the
command-line:
$ jar tf /path/to/file.jar

How are you transferring the JAR file from your Mac to Linux? Possibly
a newline-mangling during FTP? (I'm reaching, here).
