Hi,

I migrate my application from websphere 6.0/java 1.4 to websphere 6.1/java 5.
I am using hibernate 3.1 with all jar required ( cglib + asm) but I am facing following issue:
CGLIB Enhancement failed: com.pwc.lu.business.hibernate.dao.amlkyctool.PeriodicCheck

I check all jar loaded and there is no problem on this side.

Any idea?

At least some versions of 6.1 contain an asm.jar that is incompatible with hibernate. Check this:
