Hello,

I want to delete an object using its ID.

I do :

Code:

Book book = new Book();
book.setId(new Long(1));
getHibernateTemplate().delete(book);

And I get the following exception :

Code:

"not-null property references a null or transient value"

Where does-it come from ? I am forced to refresh the object before deleting it ? What is the better way to delete an object with it's ID ?

Thank you

What you should do is to session.load an object with the specified id. This returns a proxy obect without hitting a database, and then you can use session.delete() with the proxy as the argument. Should work.
