Hi Andreas, The best way that I found to solve this problem is to use two different value objects for each entity, lets call them xxxLightValue and xxxFullValue. http://xdoclet.sourceforge.net/valueobjects.html has the method by which to create these in your class. In the full object, you will use 'match="*"' and in the light object let's say you use 'match="light"'. So far, this correlates to the link above.
I suspect you are currently only creating a full object. Here is where we are going to make some changes. If you do a compile at this point, you will have a xxxLightValue that has no fields. You need to go through and add '@ejb.value-object match="light"' to all the fields you want in the light object. But be careful to only add objects to the light value that you want eager loaded. Next, when you define the aggregate or compose (again, see the above link), you are going to specify that the aggregate or compose uses the appropriate xxxLightValue. In this manner, you now have two sets of VOs. Full values containing aggregations and/or compositions, and light values with just the field values. When you call entity.getLightValue(), you will end up with a value that has no aggregates, just the entity fields. Light values are not terribly useful to grab from an entity, but I'm sure in some cases the utility is there. If you call entity.getFullValue(), the result has your relations in it, but only to a depth of one level. Because the a/c's return light values that do not have other a/c's, you reach closure on the load. hope that helps, -b > -----Original Message----- > From: Andreas Schildbach [mailto:[EMAIL PROTECTED] > Sent: Monday, January 05, 2004 8:02 AM > To: [EMAIL PROTECTED] > Subject: [Xdoclet-user] EJB Value Objects and Lazy Loading > > > Hello everyone, > > XDoclet allows to map EJB relationships (e.g. CMR) to the > generated value objects.
