RE: Client program for simple EJB tutorial
Errrg... I sent this yesterday... it doesn't appear to have made it to the list. I hope it still helps: Put the orion.jar file in your classpath as part of the manifest. This allows you to include any file that sits outside of your jar. Example: Manifest-Version: 1.0 Main-Class: com.blah.gui.control.UIFactory Class-Path: log4j.jar jai_core.jar jai_codec.jar orion.jar -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John D.

RE: Client program for simple EJB tutorial
I don't think -cp and -jar can be used together like that. Try just using -cp and place the .jar on the classpath. > -Original Message- > From: John D.

Re: Client program for simple EJB tutorial
Hi Ken -
Here's a sample client program.
Cheers

a servlet as a client for an EJB. Does someone have the code for a 'command line'

Re: Client program for simple EJB tutorial
Ken,
Your timing is impecable. I just got done
figuring out how to get a client program (static void main) up and running about
four weeks ago. The message below is the message I sent another individual
that was having problems as well. He's said that the document I put
together worked perfectly the first time around.
Everything I've detailed below is basically doing
the 'CabinBean' example from O'Reilly publishings 'Enterprise JavaBeans'
book. I'd be happy to fill in the blanks if you get stuck on
anything.
Let me know how it works for you:
ejb-jar.xml===
There seems to be some issues with security role
mapping, that I'm stilltrying to figure out. I had to remove the
tags fromthis file or else I'd get an exception
that admin was not allowed to executeany of the methods on this bean.
I'm working on setting up a for admin, but am
having some difficulty. It works ifyou leave those out
though.
Also, make note that the ejb-name is
'CabinBean'. This comes into playlater.
JavaBeans 1.1//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd">
This Cabin enterprise bean entity represents a cabin on a
cruiseship.

Container

This role represents everyone who is allowed full
access
to the cabin bean.

This is required for the application client
'Client_1.class'. This existsin a META-INF directory where the
Client_1.class is being executed from.Notice the ejb-ref-name is
'ejb/CabinBean'. This should be the same as theejb-name in
ejb-jar.xml, with the 'ejb/' in front of it.

Client_1.class==
This is the client program from O'Reilly publishing
'Enterprise JavaBeans'book. Notice a couple things:
(1) Instead of using a function called
'getInitialContext', I justinstantiate new InitialContext(). You of
course need a jndi.properties filethat can be found in the classpath upon
startup with the requiredinformation. I'll provide this a bit
later.
(2) When I do the lookup. I
do:
Object ref =
jndiContext.lookup("java:comp/env/ejb/CabinBean");
Where as the book does:
Object ref =
jndiContext.lookup("java:comp/env/ejb/CabinHome");
It SHOULD be the ejb-name you supplied in the
ejb-jar.xml file. This wasone of the big reasons it could never find
my bean.
