Title: RE: [jBoss-User] NotSerializableException

Ok, sorry, it's pretty obvious that the bean field must be serializable :) , but i dont see why i must make a subclass of InitialContext in order to use it inside the stateful beans. Its something that (almost) everybody needs inside his beans (at least i need it everywhere), or is it forbidden to use InitialContext inside a bean and i must use other thing?   Thanks in advance ----- Original Message ----- From: Nortje, Andrew To: 'jBoss' Sent: Monday, February 12, 2001 5:13 PM Subject: RE: [jBoss-User] NotSerializableException Francisco The deal is that all bean members of a class must be serializable so they (the beans) can be passivated. The InitialContext issue (this may be an over simplification), create a new class that extends InitialContext and implement java.io.Serializable, and use it. > -----Original Message----- > From: Francisco Andrades [mailto:[EMAIL PROTECTED]] > Sent: Monday, February 12, 2001 2:12 PM > To: jBoss > Subject: [jBoss-User] NotSerializableException > > > Hi, we have a set of stateful session beans that have some fields.
