Yes, It is working fine while using single persistence unit with LocalHT, what happen if I want to use mina or hornetq. Is still applicable using single persistence unit? I tried HT server starts good, but process fails...while creating the knowledgesession from jpaknowlege service, the environment breaks bcos of btm transactionservice
(i am using com.mysql.jdbc.jdbc2.optional.MysqlXADataSource  not btm) 

I got the following error...
