How can i maintain a user session between servlets and stateful session ejbs?

SCJP 1.5/1.6 Exam Kit

!!!Answer!!!- From Technical Expert

HttpSession and EJB Stateful session is different. HttpSession is in servlet container and EJB Stateful session is in Application Server EJB Container.

You can maintain the user session between servlets and stateful session ejbs using Handle Object of EJB.

Step 1. get the Handle Object using your
EJBObject.getHandle() method.
Exmaple : Bean lbean = lhome.create();
then Handle hd = lbean.getHandle();
Step 2.
session.setAttribute("handle",hd);
You can have question like why we can't store the session bean itself ?
answer is : ejb session bean is very heavy .
Step 3.
When you want the EJBObject just
Handle hd = session.getAttribute("handle");
Bean lbean = (Bean)hd.getEJBObject();
