    I am trying to access an EJB from a JSP and have the foll code piece: (i am using weblogic 6.0)
    ..............
    String url = "t3://localhost:7001";

    public Context getInitialContext() throws Exception {
    Properties p = new Properties();
    p.put(Context.INITIAL_CONTEXT_FACTORY,
    "weblogic.jndi.WLInitialContextFactory");
    //p.put(Context.PROVIDER_URL, url);
    return new InitialContext(p);
    }

    String getStackTraceAsString(Exception e)
    {
    // Dump the stack trace to a buffered stream, then send it's contents
    // to the JSPWriter.
    ByteArrayOutputStream ostr = new ByteArrayOutputStream();
    e.printStackTrace(new PrintWriter(ostr));
    return(ostr.toString());
    }
    %>
    <%
    String op="";
    try {
    // Contact the AccountBean container (the "AccountHome") through JNDI.
    Context ctx = getInitialContext();
    out.println("initial context got !!");
    DemoHome home = (DemoHome) ctx.lookup("demo.DemoHome");
    out.println("home got !!");

    %>



    <%
    Demo ac = null;
    try {
    ac = (Demo) home.create();
    out.println("create called!!");
    if (ac==null)
    out.println("ac is null!");
    }
    catch (Exception ee) {
    out.print("exception 1");
    }


    %>


    <%
    try {
    out.println("going to call method!");
    if (ac!= null)
    op = ac.demoSelect();
    else
    out.println("ac is null->error!!");
    out.println(ac.demoSelect());
    out.println("string got!!");
    out.println(op);
    }
    catch (Exception e) {
    getStackTraceAsString(e);

    e.printStackTrace();
    out.println("error 2");
    }
    }
    catch(Exception e)
    {
    out.println("error 3!");
    }
    ..................

    It gives an error on trying to access the method "demoSelect".
    e.printStackTrace gives the output:
    -------------------
    java.lang.RuntimeException: javax.ejb.EJBContext.getEnvironment is deprecated in EJB 1.1. EJB 1.1 compli
    ant containers are not required to implement this method. Use java:comp/env instead.
    <--------------------

  2. your ejb is wrong.[ Go to top ]

    Check your code of EJB.
    the method getEnvironment() has been Deprecated.

  3. EJBContext error - lookup() method error[ Go to top ]

    Your lookup() code is wrong that is shown above. You are using EJB 1.0 type of lookup. You need to use lookup("java:comp/env/....") which is part of EJB 1.1 spec.

    Hope this helps.

  4. Error Found - in EJB[ Go to top ]

    Yeah .. I found out that the EJB's setSessionContext method was referring to getEnvironment() method which is now deprecated. This was what was giving a problem. I just removed that invocation and the whole thing worked fine.

    Please note that I did not make any changes in the JSP at all.
    So, I guess, the JSP lookup code is as per EJB 1.1 reqmnts.

    Any comments, Chintala?
