I took me a few minutes this afternoon to figure this one out. JDeveloper can automatically generate EJB3 session beans for you that have methods to work with entity objects by selecting ‘generate session facade methods‘. These are the normal methods you need to insert, remove, and query entities. Later when you’ve added some...

Did you know that it’s very easy to run a single test in a unit TestCase with JDeveloper? Open the TestCase in the structure view, select the method you want to run, right mouse button, select Run. You can also debug a single test the same way.
