Set the transaction isolation level as [TRANSACTION_READ_UNCOMMITTED]. It is used to read uncommited values ina transaction.

Hi Arun Thanks For your Reply

I set the isolation level in weblogic-ejb-jar.xml as follows

<transaction-isolation>
<isolation-level>TRANSACTION_READ_UNCOMMITTED</isolation-level>
<method>
<ejb-name>InvoiceManagementTest</ejb-name>
<method-name>*</method-name>
</method>
</transaction-isolation>



and i deployed that ejb on server but its giving error

Is it working fine without the isolation level setting?

I am sorry, I can not easily tell from the post. What version of Weblogic are you using? (Implied EJB version as well) Are you using KODO/OpenJPA or Hibernate?

This will help me answer your question.
