NotSerializableException on HashMap

I've a hash map like : Map gen = HashMap<Integer, MyObj>

When I execute AccessController.doPrivileged(gen), it throws exception as follows. Can anyone help me on this. 

java.security.PrivilegedActionException: java.io.NotSerializableException: java.util.HashMap
    at java.security.AccessController.doPrivileged(Native Method)...

This code is getting executed in Weblogic environment.

The objects you store in the Map (in your case MyObj) should implement the interface java.io.Serializable

Your key is Integer which is Serializable by default. What is inside MyObj? I mean are there any objects inside MyObj?

MyObj should implement java.io.Serializable.
