Hello, I have a problem using lazyInitialisation with one class.
My application is using apache tomcat and java.

java.rmi.UnmarshalException: Error unmarshaling return; nested exception is:
java.io.InvalidClassException: org.hibernate.LazyInitializationException; local class incompatible: stream classdesc serialVersionUID = 2437230972983101293, local class serialVersionUID = -1717452178421177016

Can anyone help me out? Thanks
