Subject [jira] Commented: (OPENJPA-602) NullPointerException at
Date Wed, 04 Jun 2008 12:45:45 GMT


Tim Kaltenbrunner commented on OPENJPA-602:


I have the same problem at my current project. I have an existing database structure created
with Kodo JDO. Now I want to use OpenJPA but keep the old database structure. Will someone
fix this problem or will you only throw an exception. I am also not sure if the specification
specifies that this case should be possible but JDO implementation do support it and therefore
it would be nice to have it in OpenJPA . 

Cheers Tim
