I have try but it does not work. On your response, I thought the problem is that I use the same name for all the files, that is adder.jar, adder.war and adder.ear.
I have proved to give them different names, that is adder-ejb.jar, adder-web.war and adder-app.ear to the files and try again and did not work.
In this post I include the descriptors because if there is something wrong,

Trying a different account didn't help with JavaService.
So I tried the suggestion of using JBossNative. Initially this had an error during startup until I tried the suggestion of using a different account (the error was very different than what I was getting from JavaService -- but I was desperate). Now it is working! So the fix seems to be to use JBossNative AND to not use the system account.
Thanks for your help both of you.

jbpm use database to store the process information and context because jbpm is designed to execute long running processes.. (like process that run for years).. so you must persist the state of all running process to restore the state in case of your machine goes down..
or in case that you have the process in a wait state like wating for a human task end...
I Hope it helps...
Let me know if i can help you with something else...
If you only wanna a process machine.. you can try using PVM that is a Process Virtual Machine that is independent of language and you can use it with out of any persistent engine..
