Custom Tag Library - error in IWS

Question

My environment: Solaris 2.7, IWS4.1 SP3.
I currently try to run the Custom Tag Library example from IWS itself in
server_root/plugins/samples/servlets/taglibs. I follow the instructions to
config the IWS but fail to run the example. I turn on JSP debugging and
find the following error messages:

IWS keeps aborting JVM and one can see from the log that it abort jvm when
trying to :

I have tried another much simple Custome Tag Library example that only contain a simple tag that do output to page, but still getting the same error.

Answer 1

I had the same issue with WAS 6.1.0.2. I do not have a solution, but a workaround. I hope the workaround I have works for you too.
In my case, I have the TLD files deployed in a jar. So, the JSP 2.0 container is supposed to read those TLD files from the jar file. Since that was not happening, I extracted the TLD file from the jar file and placed it under my web project's WEB-INF folder.
I restarted my server and after that it worked.
Look at the IBM site to see if they have come up with a patch for WAS 6.0.
Hope this helps.
