Handling of Transactions in EJB 2.1 version

[Ravi Kiran Va]

Hi ,

We are using EJB 2.1 version .
I am having some confusion in understanding EJB Transactions in 2.x versions of EJB .

In our Application , inside the session bean class we are not using any UserTransaction and on to the weblogic-ejb-jar.xml file the tag <transaction-descriptor></transaction-descriptor> is just empty .

I am having a query here , can you please tell me who is actually handling the Transactions ??

Can you please share your ideas on this .

Thanks in advance .

The <transaction-descriptor> tag in weblogic-ejb-jar.xml supports just one attribute which is the transaction time-out.

It is in the ejb-jar.xml where the type of transaction is specified (Container vs Bean). It's also here that transaction attributes for individual methods are specified.

Example

<ejb-jar>
  <enterprise-beans>
    <session>
      <!--other stuff-->
      <transaction-type>Container</transaction-type>
    </session>
  </enterprise-beans>

  <assembly-descriptor>
    <container-transaction>
      <method>
        <!--other stuff-->
        <method-name>*</method-name>
      </method>
      <trans-attribute>Supports</trans-attribute>
    </container-transaction>
  </assembly-descriptor>

    
</ejb-jar>
