Re: [eclipselink-users] eclipselink.jdbc.batch-writing

Hi James,

I use this:
<property name="" value="" />
with the oracle 10g XE database and its jdbc drivers.

I already enabled logging, but see no other error.
I use tomcat, maybe that is the problem?

What application server are you using?

Ensure that you are using the Oracle9Platform and Oracle JDBC driver.

When I add the <property name="eclipselink.jdbc.batch-writing" value="Oracle-JDBC" /> to my persistence.xml

I get the following error when the transaction tries to commit:

javax.persistence.RollbackException: Transaction rolled back because transaction was set to RollbackOnly.

Can anyone tell me why this exception is thrown?
