java.lang.IncompatibleClassChangeError: Implementing class deploying to app engine

Question

I wrote a couple of REST services using Jersey 1.13 on JRE 1.6. Everything runs fine locally, but after I deploy to GAE I get this error:

****Uncaught excep         


        

Answer 1

The instructions on this post took care of my problem.

Apparently the jersey-server 1.13 jar is compatible with asm3.1 and GAE 1.7.1 needs ASM 4. Using the Jar repackaging tool jarjar you can deploy a asm 3.1 jar that will play with asm 4.

You may need to use JarJar version 1.3 if 1.4 gives an error message.
