Google AppEngine problem -- java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter

I'm putting this question in this forum because I'm not sure where else it would belong. If some admin decides to move this, no offense will be taken. I'm converting a Struts/Hibernate application over to Google App Engine. When I try to start up the front page of my application, I get the following error on my console. Can anyone help me with this? I'm using Eclipse Indigo, and I have asm-3.3.jar in my Java build path, and it's also in my WEB-INF/lib.

Just did a google search for "org.objectweb.asm.ClassWriter" and hit a bunch of reports of exactly this error!

Most of the answers seem to be some version of the following:

You have an incompatibility between the version of ASM required by Hibernate (asm-1.5.3.jar) and the one required by Spring.

I added an earlier version of the asm jar, and that solved the problem.
