Richard Schilling commented on JDO-582:
---------------------------------------

I had initially set up the test with two configuration files, just like you 
suggested, but I didn't understand by looking at the code and the XML file how 
both class names get added to the search list.

So, I think I just need more information on how to setup the .xml files and 
actually make the call.  

On my first attempt I tried using one configuration file with two persistence 
manager factories defined.  I got an error - something about not being able to 
have duplicate properties defined.  Here's what I had in one file:

    <persistence-manager-factory>
        <property
            name="javax.jdo.PersistenceManagerFactoryClass"
            value="bad.class.negative9a.1"/>    <!-- name is arbitrary  class 
name -->
    </persistence-manager-factory>  
    <persistence-manager-factory>
        <property
            name="javax.jdo.PersistenceManagerFactoryClass"
            value="bad.class.negative9a.2"/>     <!-- name is arbitrary  class 
name -->
    </persistence-manager-factory>  


Then I tried using the two configuration files as you suggest, putting the 
definition for each PMF in a separate file.  But, I got an error there as well, 
with the following code being executed in the test method:

            ClasspathHelper.addFile(
                    JDOCONFIG_CLASSPATH_PREFIX + "/Negative09/09a", loader);
            ClasspathHelper.addFile(
                    JDOCONFIG_CLASSPATH_PREFIX + "/Negative09/09b", loader);

            // call getPersistenceManagerFactory(classloader);


So, how do I specify the class names in the .xml files?

Also, I didn't expect to be actually using a real class name as you suggets 
(e.g. javax.jdo.JDOHelperTest.BadPMFNoGetPMFMethod).

Can you explain this a little more please?  Would be very helpful in my 
understanding of PMF internal behavior...

Thanks.
