This week's book giveaway is in the Java in General forum. We're giving away four copies of Java by Comparison (eBook) and have Simon Harrer, Jörg Lenhard, Linus Dietz on-line! See this thread for details.
I moved to Hibernate Persistence instead of open JPA persistence providerIMPL due to Jboss eap 6.4 open JPA issue earlier in persistence.xml it is mentioned as below for OPEN JPA
<property name="openjpa.TransactionMode" value="managed"></property>
<property name="openjpa.ConnectionRetainMode" value="always"/>
Now I changed to HibernatePersistence and added hibernatec3p0 properties instead of above property.
