Posted: Tue Feb 17, 2009 4:06 pm Post subject: Database application: error before anything!

Hi there. I'm creating a DB application. I'm following this tutorial.
http://www.netbeans.org/kb/docs/java/gui-db-custom.html
I'm using a self-made DB called Fornitori. I've used the wizard mode to build the skeleton of the application, and immediately after doing that, i try to compile my project, and this is the result:

Code:

17-feb-2009 16.58.26 org.jdesktop.application.Application$1 run

Did you add the driver to the library folder within the Project? Might be missing some jar file that needs to added to the library...

This BUG might be CAUSED BY ---------- @Basic(optional = false) before a @joincolumn reference When changing a column from a basic to a joincolum remove the @basic(optional = false)
