Re: [eclipselink-users] Class Weaving

Hi tom,

I also enabled the eclipse link finest logging and found the following
logging for the entity Relation 
[EL Finer]: 2009-07-14
22:48:07.14--ServerSession(18812899)--Thread(Thread[main,5,main])--Class
[com.oracle.healthinsurance.orm.entities.Relation] registered to be
processed by weaver. 

But not logging stating 

[EL Finest]: 2009-07-14
22:50:26.859--ServerSession(18812899)--Thread(Thread[main,5,main])--Weaved
persistence (PersistenceEntity)
[com/oracle/healthinsurance/orm/entities/Relation]. 

+ change tracking + FetchGroupTracker 

Also in my test case I set the debugging properties you mentioned

	@BeforeClass
	public static void setup() {
		System.setProperty("eclipselink.weaving.output.path",
"D:\\projects\\ohi_next\\ohi\\trunk\\ohi-orm\\weavedclasses");
		System.setProperty("eclipselink.weaving.overwrite.existing","true");
	}

Again I cannot see the weaved class.
