Problems with SELECT INTO OUTFILE with EclipseLink JPA Provider (no replies)

We have developed an application that is deployed into weblogic application server.
This application executes one SELECT INTO OUTFILE statement using one defined JDBC resource. Database access uses JPA with EclipseLink provider with next configuration:

<persistence-unit name="HandleData" transaction-type="JTA">
<jta-data-source>jdbc/HandleData</jta-data-source>
<properties>
<property name="javax.persistence.ddl-generation" value="update" />
<property name="eclipselink.logging.level" value="INFO"/>
<property name="eclipselink.cache.shared.default" value="false"/>
</properties>
</persistence-unit



And we are obtaining the following exception while trying to execute the mentioned query in the logs:

Is additional configuration needed in persistence.xml file?

Thanks a lot for your support
