Toplink JPA Deployment problem in OC4J

Question

Hi all ,
we are having problem in deployment for an toplink JPA program in OC4J 10.1.3 .. We are using toplink essesntial and our deployed EAR structure is
aaplication.xml
rmwtoplink.war
the content of application.xml is as
<display-name>rmwtoplink</display-name>
<module>
<web>
<web-uri>rmwtoplink.war</web-uri>
<context-root>rmwapplist</context-root>
</web>
</module>
the content of war file as below :
web-inf\web.xml
web-inf\classes\META-INF\persistence.xml
web-inf\classes\<classes>
web-inf\gnf\<jsp pages>
when ever a pages are called those do not use entity manager / jpa call are loading perfectly , but the pages which have used jpa are nt diplayed , we check the error messages , it just halts after following codes :
EntityManagerFactory emf =
Persistence.createEntityManagerFactory(jpaSource);
It seems there is no exception that is even thrown in page or opmn log .
The same program is running fine in Jdveloper 10.1.3 /
Is there any way where we can get the actual error message ?
we are using toplink.jdbc.url for connecting the database .

Answer 1

Here is little more insight for the problem , further check reveals that :
start connecting rmwtest
exception occured for connection test , Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
The Connection descriptor used by the client was:
//localhost:1521/ORCL
we do not have any idea how is localhost:1521/ORCL picked up , in our persistence.xml we have
where as rmwtest defined in persistence.xml as
<persistence-unit name="rmwtest" transaction-type="RESOURCE_LOCAL">
<provider>oracle.toplink.essentials.PersistenceProvider</provider>
<class>rmw.gnf.entity.ServSesnUser</class>
<class>rmw.gnf.entity.RmwData</class>
<class>rmw.gnf.entity.GnfData</class>
<properties>
<property name="toplink.logging.level" value="FINEST"/>
<property name="toplink.jdbc.driver" value="oracle.jdbc.driver.OracleDriver"/>
<property name="toplink.jdbc.url" value="jdbc:oracle:thin:@middb.1dc.com:1621:ukdbins"/>
<property name="toplink.jdbc.user" value="****"/>
<property name="toplink.jdbc.password" value="********"/>
</properties>
</persistence-unit>
