EJB class cast exception

I have a graph class. It takes the type of
the vertex and edge as parameters:
mmiGraph<String,edgeNode>.
(String-Vertex, edgeNode class edge object type)

It is de-serialized from the disk and used
for direction computation. This happens through a singleton wrapper.

It works perfectly fine on OC4J embeded in JDeveloper 10g. However, when
I deploy it on JBoss, which is the server side deployment platform, I
get a class cast exception when the graph is to be initialized.

I have no idea why this is happening.

Can you please help me out!
 
Don't get me started about those stupid light bulbs.
