Hi,

I have a problem on clistering with an application based on spring.

When two instances of my application are running, I can navigate through the site correctly except when I try to do some operations that involve the change of some session attributes...

The error is on a spring class and I've tried to set this class as Serializable, but the error then is on another class and then another one...

I have this stacktrace:
