kconner Mar 14, 2008 8:58 AM (in response to lafbarbosa)You can handle this in the same way as any other EJB client would, this is not specific to the ESB.

2. Re: Actions that call another kind of EJBs, like Session Bea
lafbarbosa Mar 14, 2008 10:23 AM (in response to lafbarbosa)Ok, but how can I forward message to the EJB from the ESB?
I am imagining only a service (EJB in the machine A) that is accessed by a client (in the machine B) through the JBossESB (in the machine C). So, the ESB will only forward the message to the service (EJB).
When I have an MDB EJB, I write an action to route/forward message to the MDB, but which kind of action may I write for the Session Bean can receives the request? Can you give me an example of action into jboss-esb.xml?
Thanks in advance!

domkun Mar 18, 2008 2:18 AM (in response to lafbarbosa)Hi Luiz,
have a look at http://jira.jboss.com/jira/browse/JBESB-1350 it was my first attempt to call session beans with a "generic" action.
Maybe you can use it (or parts of it). It is not well testet, it was just a quick hack, so maybe it is better to review the code :) -

Good timing, I was just discussing this task with someone yesterday. Your posting has reminded me to update the task :).
We are going to take a look at this for the next release of the ESB. -

Hi domkun,
In the university they ask as to Program a 'code generator' to integrate a composant or one service of a composant on the ESB of JbossEsb
I found your JIRA and i think that it will be so helpful for me.
am newbie in J2EE and Jboss
so i think the first thing that i have to do is studying the proprieties of an EJB ....
then i'll try create an EJB and try to use ur Class.
my question is, do you have other documentation about your EJBProcessor
and would you accept to help me (can i have your mail plz ? )
thanx
(sorry for my bad english :( ) -

From the stack trace it looks as if there is an issue with remoting.
If you can wait a few days then we will have an ESB that works with AS4.2.2GA (4.2.1 ESB release was tested on AS4.2.1GA) and this will hopefully fix your issue. It will certainly provide us with a good platform to investigate further if the issue still exists.
The release candidate for 4.3 will be out very soon. -

msandoz May 1, 2008 5:32 PM (in response to lafbarbosa)A friend helped me out - it turns out i had the wrong copy of my ejb client jar in the esb. i used one that had the deployment descriptors in it so it tried to deploy a mangled version of the ejbs and that blocked the right version of the ejbs from getting loaded. so - my bad. lesson for me is: watch out what you put in the esb directory!
