failed to lazily initialize a collection of role

Question

Hi I have two classes like this:

public class Indicator implements Serializable {
...

    @OneToMany(mappedBy = \"indicator\",fetch=FetchType.LAZY)
    priv         


        

Answer 1

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.
