Re: Use WLS connection pool
kevin,
Do you have any configuration sample for sharing? For example, a
persistence.xml snippet?

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

Re: Use WLS connection pool
Posted by yu wang <wa...@gmail.com>.
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.
