Hi guys,

I am having a problem with the lazy loading of Hibernate. I have set lazy to default value ie: lazy="true" in my HBM files. So whenever i try to retrieve data from the child table, its throwing Lazy Initailization Exception could not initialize proxy - no Session. I tried to load the parent class and initialize the parent object, but the exception remains the same.

My application has Spring so I am using HibernateTemplate. I cannot set LAZY="false" as it leads to poor perfomance and speed.

Please help me in this matter.

Thanks in advance.

A LazyInitializationException happens when you try to access an object association outside the session:

-- start session --
load objectA
-- end session --
objectA.getB() // Exception

Setting lazy=false is the wrong solution, but you found that out already.

In our app (which uses Spring and Hibernate too) the Session/Transaction Handling is set by @Transactional Annotations on the relevant methods.

My guess is that you load the object in one method, then pass it to another method or class (and thereby leaving the session/transaction) and then try to access the child.

I suggest you read the Spring manual on how to setup this correctly

Rating is welcome

Thanks Patrik.

I am very much new to Hibernate and I know little about Hibernate Annotations. I think its an alternative for HBM files(Correct me if I am wrong). I am defining the relationships between my tables via HBM files.

I will defenitely go through the Spring Manual.

I found an alternative for LazyInitializationException. A said in my previous post, I was loading the entire parent class and initializing the parent object without loading the parent object I needed. Now I am loading the parent object and trying to access the data through that parent object. Its working fine.

Thank you all for looking into the post.

@Transactional is a Spring annotation, not a Hibernate Annotation

I'm not sure what you mean by "loading the entire parent class etc" but if it works then fine :o)
