Well, they work fine all the way up until a call comes from a client that expects a value to be inside the stateless session bean and finds that it's been handed a totally different instance by the container!
That's why you should only put READ-ONLY variables in an SSB.

Hi Kyle
Can you please explain it further. How this whole thing is managed by the container and why there is wrong data( or same data even when the input changed) returned when it does read_write into private HashTable or any other structured data.
Thanks
 
It is sorta covered in the JavaRanch Style Guide.
