Hi all,
I currently have a quesion about using the EAGER/LAZY. I have a class:
| public class Folder implements Serializable {
| ...
| @OneToMany (mappedBy="folder", cascade=CascadeType.ALL,
fetch=FetchType.LAZY)
| public List<File> getFiles() {
| return files;
| }
| ...
|
After I load a folder from client, then use getFiles() to get all files, I got
exception:
| org.hibernate.LazyInitializationException: failed to lazily initialize a
collection of role: Folder.files, no session or session was closed
|
However, when I changed the LAZY to EAGER, no exception happened. But, I really
do not want to client to load all files before it calls the getFiles(). How
should I do? Any help will be appreciate. Thank you in advance. I use EJB RC5
and JBoss 4.0.4
