I have JPA mapping to HSQLDB and persistence.xml reads as below:

<persistence-unit name="HMC">
  <jta-data-source>java:hmc</jta-data-source>
  <class>org.hmc.jpa.models.BloodGroup</class>
  <class>org.hmc.jpa.models.ContactInfo</class>
  <properties>
    <property 
      name="hibernate.transaction.manager_lookup_class"
      value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
    <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
  </properties>
</persistence-unit>

But whenever application is deployed, it JBoss throws RuntimeException saying:
Specification violation [EJB3 JPA 6.2.1.2] - You have not defined a non-jta-data-source for a RESOURCE_LOCAL enabled persistence context named: ABC

I also have datasource defined in JBoss. Is there anything that I am missing in the configuration?

    I got it working by removing transaction-type="RESOURCE_LOCAL" and changing java:hmc to java:/hmc. But now my application has another problem whenever I try to persist.

    It throws : java.lang.IllegalStateException: A JTA EntityManager cannot use getTransaction()

    Can anybody tell me how to get a connection and start transaction in JTA mode?
