UndeclaredThrowableException Caused by: java.io.NotSerializa

[tartan]

Hi,

I'm currently migrating an application from JBOSS 4.0.0DR3 to JBOSS 4.0.4.GA. I've made no changes to code, just deployed the ear that was working on 4.0.0 to the 4.0.4 deployment. I get lots of UndeclaredThrowableExceptions Caused byjava.io.NotSerializableException as in the example below. I'm presuming this is a configuration problem since as i say it worked on 4.0.0. Any ideas would be much appreciated.

Of course, i can work around this problem by making the object implement Serializable, but i'd really like to understand why this change is necessary in moving from on jboss version to the next - if anybody has any ideas i'd be very grateful. Thanks.
