Apache OJB: How can I change the eager / explicit / lazy loading behaviour at runtime?

Question

Hi, we use Apache OJB for persistence.

Usually we use the proxy mechanism to have a lazy loading behaviour of 1:n relationships. The proxy mechanism is defined in the repository definition file.

Now we have one special situation in that I want to force OJB to load all related objects at once, immediately.

I.e. this query: Collection<FooClass> result = (Collection<FooClass>) broker.getCollectionByQuery(query);

is supposed to load all related classes (e.g. BarClass) immediatly. In all other situations the BarClass should be loaded lazily.

Is there a possibility to change the loading behaviour at runtime?
