Jbpm4 and existing database
Hi all,
I hope someone can help me.
I had to move my Jbpm4 to a Jboss 5.0.1 (before it was running on Jboss 5.0.0).
I followed all the process to install the Jbpm on Jboss. I didn't need to install the JBPM schema because I already have it and it's already filled in with data.
Now, if I start a brand new process in my app, everything works fine but if I try to execute the next step of the business process for an existing record I get this error:
10:32:24,041 INFO [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.CompleteTaskCmd@63ab94

I couldn't find any valuable help in internet.
It's like the JBPM is not able to "hook" itself to an existing database.
Do I have to execute some other step to synchronize the JBPM with the database?
Any help is highly appreciated.
