Hi,

Problem is in mapping, not in cglib, probably "age" is null in DB.

It`s weird because i got ages for all persons in the table.

Then, it`s not because it`s null.

Do u have any other sugestion?

Try doing what the exception recommends - set hibernate.cglib.use_reflection_optimizer=false

Where ( or how) can i do that?

Look for it in the documentation.

Everything i`ve been doing for one week is based on hibernate docs (actually from the site).

It has helped me a lot, however, i think that hibernates documentation has some scattered pieces of information that sometimes are hard to put together.

When i get home from work, i`ll sure take a look at the documentation and try to solve the problem, but if it`s a simple thing to do (or to explain), i`d appreciate any help.

Thanks,
ltcmelo

Just use the search function of your web browser or PDF reader!

Generated code does this: person.setAge( ((Integer)args[0]).intValue() );
It can throw ClassCastException or NullPointerException, reflection does the same in native code and I do not think message will be more clear.
