Reinhard Sandtner commented on OPENJPA-2632:
--------------------------------------------
hey,
my ear looks like this (simplified for the sample - see also
https://github.com/struberg/was_bugs/tree/master/was_bug19)
{noformat}
ear
| - lib
| | - myjar
| | | - TheEntity.class
| | | - persistence.xml
| - mywar
| | - WEB-INF
| | | - classes
| | | | - Result.class
| | | | - ServiceUsingResult.class
{noformat}
as i understand, the entity gets loaded via the ear-CL and this did not know
the {{Result.class}}. i've not found any restrictions in the spec that the
result class must be in the same classloader as the entity.
> select new not working if result class is not in same classloader

> in my case i'm using an ear with multiple war files.
> the entities are located in ear/lib and my select new result class and the
> service which loads it are located in a war (doesn't matter if in WEB-INF/lib
> or WEB-INF/classes)
> openJPA uses the CL stored in QueryImpl but this one can not load my class.
> imo if the class can not be loaded with the stored class loader, we can try
> to use the TCCL to load the class.
