[jboss-user] [JBoss/Spring Integration] - NotSerializableException: AbstractEntityManagerFactoryBean$M

[alpheratz-jb]

Question: has anyone seen the following before?

[This is with 'All' config JBoss 4.2.1GA. and Spring 2.1M4 and Toplink Essentials JPA 2.0-b58g]


  | 14:36:08,158 ERROR

Why should the EntityManager stuff be serialized into the session anyway...doesn't make any sense to me!

As always, enlightenment very gratefully accepted.

Cheers,

Alph
