Ok, I moved my hello.jar and ejb jar files to WEB-INF/lib, and removed the classes for Hello from my classpath. Still getting this error:

Rick,

I'm one step behind you. I also had to copy the ejb and hello jar files to
my WEB-INF/lib directory to get the JSP to compile. Did you do anything
else?

Now, here's the output that I get:

got ctx...did lookup...found: '$Proxy3' Ouch! java.lang.ClassCastException:
$Proxy3
nah
for this code:

<%@ page import="javax.naming.InitialContext" %>
<%@ page import="java.util.Properties" %>
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.rmi.PortableRemoteObject" %>
<%@ page import="org.acme.*" %>
<%
String message = "nah";

try{
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.openejb.client.LocalInitialContextFactory" );

InitialContext ctx = new InitialContext( p );

out.print( "<P>got ctx..." );

Object obj = ctx.lookup( "/Hello" );
out.print("did lookup...");
out.println("found: '"+obj.getClass().getName()+"'");

HelloHome ejbHome = (HelloHome)obj;
out.print("have home");

HelloObject ejbObject = ejbHome.create();
//The part we've all been wainting for...
message = ejbObject.sayHello();

} catch (Exception e){
out.print( "Ouch! "+e.toString() );
e.printStackTrace();
}
%>
<P><%= message %>

Regards,
Alan

David,

Here's my JSP and relevant code.

It makes sense to me that the ejb jar has to be in the common/lib directory for JSPs since the jsp compiler is going to need that stuff to compile the servlet, but that doesn't seem to have much to do with the exception I'm getting.

Here's my JSP code: I put the HelloWorld stuff in com.zcm.intranet.ejb.test. Those classes are exactly as per the examples on the website, and they DeploymentID is /ZCMHello. I've been using this JSP for testing in and out of process, hence the extra imports.

Thanks.

Rick

Hi Rick,

Thanks for the positive feedback, I'm pretty excited about

the project

too.

I didn't test any JSPs, so I think the best thing for both

of us is for

you send me a simplified version of your code that I can use to track
down the problem and test future releases with. I'll get it

working and

send any instructions or patches to the list.

I do prefer the list, as there are usually several people

thinking the

same thing, but too afraid to ask. Thank you for asking -- it's the
first time in three years anyone has.

David,

I had to put the ejb jars in there as well to get it to compile my JSP (throwing another piece into the puzzle...JSP!). Now I'm

getting this

error (btw: this is on Redhat Linux 7.4, tomcat latest version, installed today):

Thanks for your help. I'm really excited about this project. Would you prefer I emailed this to the list, or to you directly?
