How to serialize an object which is put in the session ?

[Antony paul <an...@hotmail.com>]

I have a class which implements the HttpSessionBindingListener interface. I 
want to serialize this object and all sessions when the context is reloaded. 
It is essential because three deveopers are using the same server and if ine 
user compiles a servlet all users get a nullpointer exception. I am using 
Tomcat 4.1.18. The class implements the Serializable interface. But it is 
throwing Nullpointer exception after reload. How to know that the object and 
session is saved when the context is reloaded. I tried changing the 
debugging levels of Engine element and Context element. Still Tomcat is not 
giving any debug information about what it is oing when the context is 
reloaded. The 4.0.3 version gves better logs.
