A problem

Hi,everybody.I have a questioon is below (can i call a session bean directly in a .jsp file without through a javabean?)

I had made a test. I create a simple jsp file is aaa.jsp(just present some words).

And i deployed it and typed the url http://localhost:50000/aaa/aaa with IE. It can display.

But when I add some source code in jsp. There are some errors. The ie error message is below

(The request can't be processed.

Details: The requested resource ( aaa/servlet/aaa.jsp ) is not found)

Why it needs a servlet? I didn`t create a servlt!!

The source i added is below

try {

public Sessionccc ccc;

InitialContext ctx = new InitialContext();

Object ob = ctx.lookup

("java:comp/env/ejb/SessioncccBean");

SessioncccHome home =(SessioncccHome)

PortableRemoteObject.narrow

(ob,SessioncccHome.class);

ccc = home.create();

} catch (Exception e) {

throw new Exception("Error instantiating

Calculator EJB" + e.toString());

}

Please help me.Thx a lot.
