Hi, I have a servlet that will call an ejb. I need to find two things: 1. the code to put into the servlet to do the lookup for the ejb. 2. should I put that lookup code into the init() of the servlet and then call my business methods from another method in the servlet? Thanks, Steve
Well, EJB references are not guaranteed to be threadsafe, so you should probably look up your EJB reference everytime you do a doPost() or a doGet() method, rather than in the init() method. Just do the lookup then call the business methods one right after the other. (Hopefully you're talking about using a stateless session bean, right? If not, we've got more to talk about ) Kyle ------------------ Kyle Brown, Author of Enterprise Java (tm) Programming with IBM Websphere See my homepage at http://members.aol.com/kgb1001001 for other WebSphere information.
Thanks Kyle, Yup, SSB is what we are talking about. Per your suggestion I'll put it in a service method instead of the init(). Do you have a snippet of code perhaps that I would use to do the ejb lookup from this method? Steve

Look around page 54 of the EJB 1.1 specification. Reading that chapter should fill you in pretty well... It will basically go: // first set up a properties to correctly get an initial context //(the details are dependent on your app server) InitialContext initContext = new InitialContext(properties); Object ref = initContext.lookup("someJndiName"); MyHome home = (MyHome) PortableRemoteObject.narrow(ref, MyHome.class); MyEJB ejb = MyHome.create();
