I’m trying to build a simple prototype using MyEclipse 6.5 that employs ZK, Spring 2.5 and Hibernate 3.2

When I launch the web app I get the following error…

Any ideas???

davout,

Sorry for the inconvenience. The problem is that Hibernate 3.2 ships with the ASM 1.5 libs and Spring 2.5 ships with the 2.3 versions of the ASM libs, it’s a library conflict.

I *believe* if you go to Window > Prefs > MyEclipse > Project Capabilities, and drill down to the Hibernate 3.2 library container that contains ASM that is in your project’s build path (I think it’s the AOP container), if you just remove it from there then remove your deployed and redeploy your project, Hibernate will then use the Spring ASM 2.3 library instead and work.

If that doesn’t work, try it the other way around.

Thanks….

The solution is to remove the asm jar file from the ‘Spring 2.5 AOP’ bundle

It now works!

Thank you for posting the solution.
