title: How to update Hibernate if database changes
body: <p>For example, I created the hibernate.cfg.xml and generated the classes automatically (hbm.xml's).</p>
  
  <p>If I realize there's something to be modified, added or deleted from the database, normally I'd have to change the database by hand and then go and change my hbm.xml's source code by hand too.</p>
  
  <p>Is there a way to update without the need to remove the code and re-generate or modify code by hand?</p>
  
  <p><strong>EDIT: What I meant is changing the data base directly and reflecting those changes in the Java code. Sorry, I wans't very clear because I didn't know there was another way around.</strong></p>
