RE : IOException while loading persisted sessions: java.io.WriteAbortedException

Tomcat 5 is configured to make sessions persistent by default.
If you have an object in your session that is not serializable, Tomcat will complain that it is not able to manage persistent sessions with your object.
To avoid that, you can :
 
- make your object serializable (but LayoutEventDescription is not one of your classes)
- disable persistent sessions in Tomcat. To do this, just add the following line in your Context entry in Tomcat server.xml file : 
 
<Manager className="org.apache.catalina.session.StandardManager" pathname=""/>
