Hi, I'm working on a J2EE application with Servlets and EJBs. One of the tasks is to do a big calculation (10 min-1 hour). In order not to use all CPU resources for these calculations, I have an asynchronously design pattern and do the calculations one by one.
To this end I use a Servlet that sends a message with Java Message Services (JMS) to a queue. A point-to-point Message Driven Bean is pulling messages from the queue and is subsequently calling a Session Bean that does the calculation. Until so far, this obeys "EJB Design Patterns of Floyd Marinescu, Chapter 1 ,Message Facade". Here comes my question: The results of the calculation, once the calculation is finished, are sitting in the Session Bean (in memory). Now I want to access the calculational results of the session bean from within a servlet. How can I do this? In some way the data in the session bean should be associated with a user session of the servlet. But I think I can not access session attributes of the HttpSession nor those of the ServletContext. By the way, I don't want to persist them in a database because it 's a lot of data and it's not clear whether data is needed in the future. This is undoubtly an issue that occurs in more applications. Can someone help me with this one?
