On my persistence.xml I can't reference a jta datasource through local JNDI names. When running on WAS 7.0.0.7 I got the following exception:

Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.0.2.v20100323-r6872): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Unsupported use of GenericConnection. A GenericConnection is provided during application start when creating an EntityManagerFactory for a persistence unit which has configured one of its datasource to be in the component naming context; java:comp/env. During application start, the component naming context will not exist, and the correct datasource cannot be determined. When the persistence unit is used, the proper datasource and connection will be obtained and used.
Error Code: 0

The JPA specifications do not require implementations to include data sources referenced through local JNDI names.

Is this a limitation of EclipseLink?!?

Thank you!

Hello,

Can you provide more information on the error though (the stack) and how you are defining your datasource?
From what you've posted, it sounds like you are trying to have the JPA provider use a datasource that will not have been created yet according to Websphere - this might be a Websphere problem with the order it is using to create/resolve the datasource, not neccessarily EclipseLink.
Best Regards,
Chris

Hi Stutz,

Did you find a solution to this problem.

I am seeing the same issue with WAS 8.0 and EclipseLink implementation for JPA.

Please include your full exception stack trace, and your persistence.xml file.

We do test WebSphere 7 and 8 nightly, and do not encounter this error. When do you encounter the error, and are you doing anything different than normal?

Hi!

I am having the same error on WebSphere 7.0.0.11; if I replace eclipseLink for openJPA and works; but I need to use eclipseLink.

The stacktrace is:

Communication failure detected when attempting to perform read query outside of a transaction. Attempting to retry query. Error was: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Unsupported use of GenericConnection. A GenericConnection is provided during application start when creating an EntityManagerFactory for a persistence unit which has configured one of its datasource to be in the component naming context; java:comp/env. During application start, the component naming context will not exist, and the correct datasource cannot be determined. When the persistence unit is used, the proper datasource and connection will be obtained and used.

The persistence.xml is:
<persistence-unit name="PruebaJNDIPU" transaction-type="JTA">
<!-- <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>-->
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>java:comp/env/jdbc/test</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.target-database" value="Oracle"/>
<property name="eclipselink.target-server" value="WebSphere"/>
<property name="eclipselink.logging.level" value="FINEST"/>
</properties>
</persistence-unit>

and the resource-ref
<resource-ref>
<description>Primary database</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
</resource-ref>

Best regards

Can you post the full exception stack trace for the error? It will help to figure out when the connection is obtained and why it might be incorrect.

It is working now;

the trick is the property: javax.persistence.jtaDataSource
It should match the jta-data-source value.

The example below.


<persistence-unit name="PruebaJNDIPU" transaction-type="JTA">

<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>java:comp/env/jdbc/myTest</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.target-database" value="Oracle"/>
<property name="eclipselink.target-server" value="WebSphere"/>
<property name="eclipselink.logging.level" value="FINEST"/>
<property name="javax.persistence.jtaDataSource" value="java:comp/env/jdbc/myTest" />
</properties>
</persistence-unit>
