Subject Re: Entity name ignored in queries (0.9.6)?
Date Tue, 13 Feb 2007 08:01:13 GMT
Dain-

I've reproduced this problem and reported it at:

    https://issues.apache.org/jira/browse/OPENJPA-142

The only workaround is to add the @Entity(name="someAlias")  
annotation to the class in addition to specifying it in the orm.xml  
file.
