Due to conflict problem i am removing the above jar files from my war file. And i kept those two in JBOSS_HOME/server/default/lib.
I am able to hit the database by passing JPA queries through JpaTemplate methods. When i am dealing with entity object i am getting this error. Please help me out.
Regards
Ramesh Dasari
