java.io.NotSerializableException is thrown by WebSphere Application Server Community Edition, when the applications are stopped

Troubleshooting

Problem

Web applications use javax.servlet.http.HttpSession to store objects pertaining to a client's session. The Web components (Servlets/JSPs) use HttpSession.setAttribute() method to store objects specific to a client's session. If the objects being inserted are not serializable, (that is, the corresponding classes do not implement java.io.Serializable interface) WebSphere Application Server Community Edition might throw a java.io.NotSerializableException exception when the applications are stopped in the administrative console.
