Java EE (Java Enterprise Edition) General Discussion

This is, I imagine, a dumb question, but I can't quite figure out what is happening by looking at past postings.

When I start Tomcat I get an error : "IOException while loading persisted sessions" because some classes we use are not serializable. That makes sense - we didn't design them to be serialized.

I understand that Tomcat CAN try to persist session data across restarts. However, I do not want it to do this. I thought this was something we had to configure, but it looks like it happens by default (?)

Anyway ... any advice about how to prevent this behavior, at least for our app, would be appreciated ... really puzzled ... !

Thanks in advance for any help you can give !!
