I tried to use pojoCache on weblogic but I'm having the following problem:
 

WARN  [Initialization] Did not install PojoCache due to NoClassDefFoundError: org/jboss/cache/TreeCache : org/jboss/system/ServiceMBeanSupport

And when i try to inject the PojoCache in my class I got this error:

 <Warning> <HTTP> <BEA-101162> <User defined listener org.jboss.seam.servlet.SeamListener failed: org.jboss.seam.RequiredException: @In attribute requires non-null value: securityManager.pojoCache.

I had copy the jboss-cache.jar and jgroups.jar to the /lib of ear file, and i put treecache.xml on my project to.

At Jboss this project worked fine.

Anyone can help me?

Thanks,
