@Phon: I found something useful in EJB3 trailblazer
http://trailblazer.demo.jboss.com/EJB3Trail/services/apptrans/index.html
Im testing the loadlevel solution with a simple application:
There are 4 entities A,B,C,D.
A has OneToMany associations with both B and D (C extends A, i'll use it for
other tests)
I did the "loadlevel" method:
| public A getA(long id, List<loadLevel> levelList) {
| A a = manager.find(A.class,id);
| if(levelList.contains(loadLevel.B)){
| a.getListB();
| }
| if(levelList.contains(loadLevel.D)){
| a.getListD();
| }
| return a;
| }
|
loadLevel is an enum and i pass the list of nested object i want to load.
But there is a problem, if i call the method as you see it throws a
LazyInitializationException, but if i use the "use" the a.getListB() and
a.getListD like below
| public A getA(long id, List<loadLevel> levelList) {
| A a = manager.find(A.class,id);
| if(levelList.contains(loadLevel.B)){
| System.out.println(a.getListB());
| }
| if(levelList.contains(loadLevel.D)){
| System.out.println(a.getListD());
| }
| return a;
| }
|
Everythings goes ok, i have the prints on the server side and on the client i
can reach the collections.
Any suggestion?
