Hi, Hey i got it :)- My LoanProcess works know with Jboss 4.0.3.SP1 and jbpm.bpel-1.1.alpha.1. And i can use the logging feature. I was already familiar with jbpm.bpel.1.0-alpha.4 so that why it toke me i little time to adapt the bpel process structure to the one use in alpha-1 (JMS, partnerLink :)-. I just wan to relate that i couldn't find a solution for the issue related in this thread. The problem disappear alone after stopping and restarting my Jboss AS without changing any think in my settings. I got that problem yesterday and thougth about the advice in the jbpm.bpel-1.1.alpha.1 tutorial (switch to use Jboss 4.0.4.).
