this error seems to be thrown because of multiple persistence.xml files. does anyone know of that error message and can tell me more about what to do?

It is yet a prototype, which means there is not much jars involved yet:

- I downloaded JBoss 4.2.3
- I added ESB 4.5
- I added my datasource
- I added one new jar postgresql-8.1-405.jdbc3.jar in lib folder
- I deployed my ear. Thats all as far as I am concerned.

I have both the JBossAS and the JBoss ESB added to Eclipse Server View. When deploying to the first, the EAR works. Deploying to the second fails. Maybe my ESB is misconfigured? Anything I can test or post to help fix this problem?

Within the EAR I have:
- One jar for the myEJB module
(mentioned as module/ejb in application.xml)
- One persistence.jar containing the META-INF/persistence.xml
(also mentioned as module/ejb in application.xml)
- One empty myEJBClient.jar
- No webapp exists so far.

What I found out right now is, that shutting down the server and starting it all new leads to no error messages. My app seams to work. Then when I try to redeploy in eclipse (copy the ear into deploy folder again) without having done any changes to the files, it leads to the posted error! ?...

is there yet any solution? :( i extended my prototype with more EJB modules and unfortunately just the first table is being created. after that the error occurs and further creation fails. one more time the (this time complete) log right after deploying:

"It is possible to scope the deployment of an esb artifact, if necessary, by including a loader-repository element within the deployment.xml."

There is not yet any depoyment.xml or ESB archive. I only deploy one EAR including 2.. ejb jars and one jar containing persistence.xml. No esb yet. That will be the next step.

What do you get if you enable DEBUG for org.hibernate? Does it shed any light on the issue?

would it help to upload my ear? or send it at your mail adress, kevin?

Well, besides of this hot deployment problem, I really love all that work that was done for JBoss and ESB. I am working on a prototype with my collegue here and our goal is to presentate this app including web services, ESB and all that nice stuff. It will have to beat out our concurrent .net - prototype. And I really hope that our management will decide to use JBoss in the future, its exiting. Right now we can live with the workaround to deploy and restart the ESB server. That works and gives us all possibilities to test our app. But of course it would be great to see that this JBoss bug will be fixed, too. Thanks for all your help.
