Hi everyone,

I'd like to update an entity existing in the DataBase with a newly created object:

Suppose cat (ID=1234) exist in DB:

Cat cat = new Cat();
cat.setId("1234");
cat.setName("bob");
sess.save(cat);

Hibernate throw an exception because cat already exist.

But what I would like would be that hibernate updates the object.

Any suggestion?

Thanks,

use

Code:

sess.update(cat);

Code:

sess.saveOrUpdate(cat);

What you want is to update an existing object, not save a new one...

Read the 7.5 section of the hibernate reference guide for more informations

[/code]
