problem in deploying a hello world ejb jar file

[Sai Arunachalam <sa...@gmail.com>]

Hi,
    I have downloaded the source code for the examples that come along
with Mastering EJB
(http://www.theserverside.com/books/wiley/masteringEJB/index.tss). And
am trying to run the HelloWorld example that is there in the
WebLogic6.x samples. There are three problems that I had while
deploying this jar file.

1) The ejb-1.0.jar and ejb-2.0.jar that come along with OpenEJB 0.9.2
don't have EJBLocalObject and EJBLocalHome interfaces. And so two
classes which were implementing these interfaces didn't compile on my
machine. Therefore I just removed these 2 files (I thought we could
still do with RemoteObjects) and compiled and it compiled. So does
OpenEJB/Geronimo not support localObjects?

2) I used the OpenEJB deploy tool to generate the openejb-jar.xml file
in the jar file. It generated automatically a deployment-id called
"Hello". The weblogic-ejb-jar.xml that came along with the sample has
a tag called <jndi-name> that declares the name as "HelloHome". Is
deployment-id same as jndi-name in weblogic?

3) Also, the deploy tool threw an error when it parsed the old
ejb-jar.xml file because fo the <local-home> tag. So I had to remove
it. Any info here?

4) Fourthly, when I finally tried to deploy the jar file on geronimo,
I got the following error...

Can anybody tell me why this happens and the way around it? 

Thanks a lot for your time,
