I don't know why i am getting this exception here becuase i am using the application managed persistence context and resource local transaction.

Generelly resource local transactions can be used in Java SE client, but i am using in a Stateful Bean, but i should be able to use it here without any problem here.

Please advise.

[Manish Shah]

Do we need @PersistenceUnit annotation at line 41?.

Also I guess the default entity transaction manager is JTA, so i think you need to specify that you need Resource_Local.

In your persistence.xml file you need to remove <jta-data-source> element & add
<non-jta-data-source>RESOURCE_LOCAL</non-jta-data-source> element.

Correct me if i am wrong.
