--------------------------------------------------------------
So here is my configuration on Tomcat 5.5.. and Oracle10 which I'm using .

server.xml entry
------------------
     <Context>
            <Resource name="jdbc/testDS1" auth="Container" type="javax.sql.DataSource"
              driverClassName="oracle.jdbc.driver.OracleDriver"
                url="jdbc:oracle:thin:@localhost:1521:xe"  username="jana" password="jana" maxActive="20"   maxIdle="10"   maxWait="-1" />
        </Context>

web.xml entry at gwt-console-server.war\WEB-INF\
----------------------------------------------------------------------
<resource-ref>
  <res-ref-name>jdbc/testDS1</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
</resource-ref>

So we have *"persistence.xml"* inside *gwt-console-server.war\WEB-INF\classes\META-INF\*   which has  datasource(testDS1) entry.So Im not sure if we need to modify this file or not? I tried adding "context.xml" in META-INF with resource entry but that didn't help.
We need to tweak persistence.xml I belive to let Tomcat locate datasource and also persistemce.xml uses "org.hibernate.transaction.*JBossTransactionManagerLookup*" may be this lookup class should be changed.
Let me know if you have any fix/suggestion for this.

*Error Log*
