Re: [eclipselink-users] Can't deploy when using LAZY, can deply when using EAGER 
Hi Michael,
I am not sure if there are any issues with the way GlassFish handles this, but I can try to help you from an EclipseLink point of view. 

  The first thing to do is to see if static weaving helps:

http://wiki.eclipse.org/Using_EclipseLink_JPA_Extensions_%28ELUG%29#How_to_Configure_Static_Weaving_for_JPA_Entities
This will help us to isolate whether you are seeing an issue related to classloaders or an issue related to persistence unit configuration.

Hello All,
I develop a large JEE app, with eclipselink as the JPA provider. I switched from Toplink Essentials, where the application had no problem deploying; with eclipselink I get all kinds of Null Pointer Exceptions when I deploy the app. The problem seems to boil down to three relationships between objects. When I make them EAGER, the application deploys. When they're LAZY, it doesn't. I followed this thread <http://www.nabble.com/OneToOne-Mapping-works-with-FetchType.EAGER-but-not-with-FetchType.LAZY--%3E-Exception-when-deploying-%28SGES-2.1%29-p21711849.html>, but they did not come to any conclusions. I did find more info in the logs, though. 

The setup:

Whenever I turn any of the links marked "P" to LAZY, I get an NPE while deploying. Here's a sample, where I turned the link between EMailResource and EMailResourceBundle to LAZY:

IMHO, this looks like eclipselink finds the classes before it adds the _persistence_* methods, thus causing an NPE. 

Setup:

    * Windows Server 2003R2
    * Sun GlassFish Enterprise Server v2.1 (9.1.1) (build b60e-fcs)
    * Eclipse Persistence Services - 1.1.2.v20090612-r4475
Any solutions would be highly appreciated. I have all the logs and will be very willing to help solve this. 

Thanks in advance,
Michael Bar-Sinai
