Hi All ,
I am facing problem in calling a entity Bean from a Stateless Bean .The call flow goes
like this:
Jsp Page --> Servlet --> Stateless Bean --> Persisting the Data obtained from jsp
page into entity bean .
The jsp page & Servlet are deployed as a separate .war file on the Jboss server while
the Stateless bean and the persistence unit is deployed as .ear file on the same Server .
When I make a call to persist the values then it throws up an error at the runtime :

The stateless bean call is working fine but the call from stateless bean to the entity
bean throws up this error . The name of my data source is "system" and I have my
persistence.xml file as this :
---------------------------------------------------------------------------------------------------------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="testApp" transaction-type="JTA">
oracle.toplink.essentials.PersistenceProvider
<jta-data-source>java:/system</jta-data-source>
<!-- update to match database-->
<!-- update to match database-->
<!-- update to match database-->

</persistence-unit>
---------------------------------------------------------------------------------------------------------------------------------------
Please provide me some help to figure out the problem
