[jboss-user] [EJB/JBoss] - Can't Passivate?

[jeffreylyon]

All,

I'm getting a recurring exception:

it seems as though one of my Beans can't be passivated.  All Beans implement Serializable, although not all all members of each Bean do, such as String.  Must all members of a Bean implement Serializable as well?  How can I disable the passification of a Bean?

Thanks in advance for the help.
