The Eclipse
IDE does not provide an automatic wizard that generates a master/detail type form for you like you would find in MS Access. You will need to create the form and any connecting actions yourself.
For example, you might begin with a JPanel (if using Swing) or a Composite (if using SWT) and add controls for the master section. Then, you would need to add whatever actions necessary to update another JPanel or Composite representing the detail section.
I don't know your GUI programming background, but if you are new to
Java GUI,
you should check out the Java GUI Tutorials at:
