I am following this tutorial, I'm using netbeans 6.5.1 http://www.netbeans.org/kb/docs/java/gui-db-custom.html

When I get to the part where I create the "new entity class from database", which is in the "Customizing the Master/Detail View" section of the tutoiral. I can't ever compile because I get this error in the task list (and I get a runtime error when I run)... Atleast I think these two are related.

Error   Named queries can be defined only on an Entity or MappedSuperclass class.   Countries.java  27  C:/Users/Danny/dev/NetBeansProjects/Test/src/test

Error   Named queries can be defined only on an Entity or MappedSuperclass class.   Products.java   28  C:/Users/Danny/dev/NetBeansProjects/Test/src/test

note that all I do is do new>entity classes from database, and do exactly as the tutorial says. I stopped on the tutoral at the "Adding Dialog Boxes" heading, because the tutorial writer says the application should be "partially functional" which makes me think it should atleast RUN. I haven't edited the generated code outside of what I've been instructed to do.

This is the output produced by the netbeans output console:

I'm thinking my netbeans application must be misconfigured or something, I can't seem to find anyone with the same problem as myself
