Google App Engine -- NoSuchMethodError

Question

I am trying to run a JSP in Google App Engine, and I am getting the following error message on my console. Can anyone help? I do have asm-3.3.jar in my classpath.

a little more information will help especially the context you are working.i am not sure what you mean by running a jsp — Umesh Awasthi, Jun 17 '12 at 04:35

Ok so it's in your classpath for what Eclipse? Do you have it in the WEB_INF/lib for your AE project?

I'm using Eclipse Indigo, and yes, it's in WEB_INF/lib. – Jun 17 '12 at 01:00

Have you checked out this?

Error : java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(I)V

Specifically, it may be a problem with your cglib and asm-attrs versions.

I added asm-1.5.2.jar (an earlier version), and that fixed the problem.
