[jbpm-users] how to pass sessionFactory into ProcessEngine instance?

[guoyou.jiang]

i use iBatis with jbpm, and create a ConnectionProvider for jbpm 
Hibernate,  i found when i use iBatis transaction rollback, the jbpm not 
rollback, i use JDBCTransaction.
i know the spring can pass sessionFactory into jbpm ProcessEngine, but 
how can i pass my own sessionFactory with no use spring?
