Re: [eclipselink-dev] EntityManagerJUnitTestSuite.testLockWithJoinedInhe

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Adrian,

  It looks like driverName is null in the call:

                driver = (Driver)Class.forName(driverName, true, 
Thread.currentThread().getContextClassLoader()).newInstance();

  Driver name should come from a file called test.properties.  There are 
test.properties files in <base>/jpa/eclipselink.jpa.test and 
<base>/foundation/eclipselink.core.test.  Depending on whether you are running 
the jpa tests or the core tests, those files will be used to get the driver 
name.  To override those files, put a file called test.properties in your 
<user-home> directory and override any settings you need to override.
