First of all thank You for answer.
If you look at 6 and 7 I say that after restart I can see the processes in the database... I managed to setup jbpm to use JPA and MySQL. So As I said after I restart jboss I can still see process instances in mysql database but server can't see it when it loads session... Are there other stepps other than changing JPA config to use mysql and make server load processes after restart?
