Use WLS connection pool
Hello Gurus,
I'm curious about that with OpenJPA, can we use a data source
configured in Weblogic server "JDBC Data Sources"?
Regards,
Yu Wang

Ok, It does work now, I just deploy the data source to a server first!
That is cool !

Experts:
I defined a non xa datasource in WLS which JNDI name is ds_test
Here is a snippet I am using.
<persistence-unit name="tsam" transaction-type="RESOURCE_LOCAL">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<non-jta-data-source>ds_test</non-jta-data-source>
I do not define <property name="openjpa.ConnectionDriverName"> and
conn URL in persistence.xml since I think my app should find these
information from JNDI name.
Whne I boot my app, I got error message like below:
A JDBC Driver or DataSource class name must be specified in the
ConnectionDriverName property.

kevin,
Do you have any configuration sample for sharing? For example, a
persistence.xml snippet?

Yes, that should be possible. I'm not an expert with WebLogic, but I know
this can be done (and is encouraged) with WebSphere application servers.
Specifically, you would define your datasources in your persistence.xml
using the <jta-data-source> and/or <non-jta-data-source> elements. These
would contain a jndi reference to the datasource as defined in your
WebLogic environment. This way, you can take advantage of the datasource
configuration, management, and connection pooling as defined by WebLogic.
This is definitely the recommended approach when running in an application
server.
Good luck,
Kevin
