How to use EJB in JSP...urgent!!!
hello,
i am novice programmer in EJB.
i am using weblogic 6.1 ...
my problem is how to use EJB in jsp page.
my code is as follow..but its not displaying any result.
<%@ page import="javax.naming.InitialContext,
javax.naming.Context,
java.util.Properties,
firstEJB.First,
firstEJB.FirstHome"%>
<%
long t1 = System.currentTimeMillis();
System.out.println(t1);
Properties props = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.TengahInitialContextFactory");
props.put(Context.PROVIDER_URL, "localhost:7001");
Context ctx = new InitialContext(props);
FirstHome home = (FirstHome)ctx.lookup("FirstEJB");
First bean = home.create();
String time = bean.getTime();
bean.remove();
ctx.close();
long t2 = System.currentTimeMillis();
%>
<html>
<head>
<style>p { font-family:Verdana;font-size:12px; }</style>
</head>
<body>
<p>Message received from bean = "<%= time %>".<br>Time taken :
<%= (t2 - t1) %> ms.</p>

</html>
please tell me the solution.Hi, I don't know if it may be the cuase of your problems, but you should narrow the Object obtained doing the lookup, like this:
FirstHome home = (FirstHome) PortableRemoteObject.narrow(ctx.lookup("FirstEJB"), FirstHome.class); -

1. i found that in most JSP examples, the javabeans are used but not the EJB, right? so i have a qustion, an EJB can be used in JSP or not? and how if it can? why if it can not?
...still have a lot of question ....
thanks a lotHi,

why if it can not?It can be there for more of the examples,but you can invoke the EJB from the JSP also .Actual EJB is entirely the different concept whose foundation is build on the Distributed Technology.I advice you to read the Mastering EJB which is freely available at http://theserverside.com
before starting coding.The EJB is a vast concept and requires time and strong core foundation to understand,once it is clear then you understand it true potential...
...still have a lot of question ....You queries are welcome here!!!
