Hi, Yes, that's right. Then is normal to get some exception. But when I restart my jboss server and delete all deployed stuff and also content of "data"-folder by my default jboss instance I get also the errors. After restarting I assume that jboss should delete database for me; but he doesn't that. Is there any way to tell jboss to delete the content of database by restart!? p.s. where is actually content of database saved? Thx for hints! music View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4039897#...
