Hi Mike/Jimmy,
jBPM jar jbpm-bam have persistence xml in them which points to h2. Since you are not starting h2, this might be the one crashing.
Suggest you to start h2 as well for these internal components to work. Your application data would go to mysql as you specified.
Or another way is change the persistence xmls in the jar as well.
Just a possibility. You may try that.
Regards,
Sanket.
