retrieving stateful session bean reference in a JSP

[illerd]

Ello

I'm trying to access a stateful session EJB accross multiple JSPees. I searched this forum and found a post that said to use the HttpSession interface to store and retrieve a reference to the bean. Duh. The obvious solution. Except they didn't post an example. I think i figured it out, but I'm having trouble getting it to compile (it being the JSP that is retrieving the already-instantiated session bean). Here is the error and line that is causing it:

Can't make static reference to method java.lang.Object getAttribute(java.lang.String) in interface javax.servlet.http.HttpSession.

theManager = (manager) HttpSession.getAttribute(attributeName);


The carrot would be under the opening parens after getAttribute if i wasn't too lazy to put in all the nbsp;s

I never took any java classes or anything so i don't know all of its crazy rules. i could be making a really simple type-casting error here, i dunno. I thought maybe you have to narrow the object refference but i tried that and it makes no difference to the compiler. The error occurs before it even gets to that step.

The compiler message gives you everything that you need.

Find the Java API documentation and look up the API for HttpSession.

Look around the web for a simple example program that uses HttpSessions.

If you don't understand the difference between calling a static method and invoking an instance method - get a good book on Java.

I wish I could help more - but no-one's paying me and there are only so many hours in a day.

The J2EE in your problem is incidental - you can't call an instance method without an instance.

Good luck,

See, i knew i was making some stupid simple mistake. Stupid me for not seeing it. Heh. Thanks for the help. Oh, and you're right about the java book. I need one _bad!_ I just don't want to pay for it myself, so i'm sitting here waiting for the PO to go through, and letting the compiler teach me in the mean time :)
