java.io.InvalidClassException:

[nachnouch]

Hi,

I'm new user with ejb3. I read the tutorial of ejb3 from

http://www.tutorialized.com/view/tutorial/EJB-3-tutorial-using-Eclipse
-Ant-and-JBoss/11892

But when I running the application, I receive this error:

_javax.naming.CommunicationException_ [Root exception is
_java.io.InvalidClassException_:
org.jboss.ejb3.remoting.IsLocalInterceptor; local class incompatible:
stream classdesc serialVersionUID = -3758782076801249473, local class
serialVersionUID = 595045557897063404]

I need your help
Thanks

are you using two different versions of a class? perhaps a newer and an older jar?
