SerializableException in JSF

Question

I am dealing with JSF2.0.

I received this error message

Jul 19, 2011 11:19:47 AM org.apache.catalina.session.StandardManager doLoad SEVERE: IOException while loading persisted sessions: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: edu.umn.gis.mapscript.mapObj java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: edu.umn.gis.mapscript.mapObj

what should I do ?

java.io.NotSerializableException: edu.umn.gis.mapscript.mapObj

It's telling that the class edu.umn.gis.mapscript.mapObj is not serializable. You need to make sure that it implementsSerializable. This is required when you're using JSF view and session scoped beans in a webapp which runs on a webserver which in turn saves sessions to disk in order to survive server restarts or to share with other servers in a cluster.

So, fix it accordingly:

package edu.umn.gis.mapscript;

import java.io.Serializable;

public class mapObj implements Serializable { // <--- Here.

    // ...

}

Unrelated to the concrete problem, the Java Naming Conventions state that classnames should start with an uppercase. I strongly recomment do fix it as well. Rename mapObj to MapObj (or preferably to something more self-documenting, the "Obj" suffix makes very little sense).

One of the objects you are storing in your session (or one of it's members) does not implement Serializable.

All of your SessionBeans (and their Members) must implement Serilizable to be distributed around the cluster or stored into the Database!
