best suitable eclipse swing plugin

what would be best plugin for eclipse in GUI Builder (e.g. swing), ill transfer to eclipse from netbeans.
is it v4all, jigloo, windowbuilder or etc?

in
v4all - when i saved it for the first an error occur, it said "a resource already exist . . . . . " i dont know what that means, i cant run the program
jigloo - i dont know how to set the JPanel because it is larger than the frame, when i place it in a JScrollPane and drag the JPanel longer(height)
the JPanel stretch but when it elapsed the edge of the JScrollPane/JFrame it makes invisible the part that elapsed.
windowbuilder - i didnt tried this.

can someone advise me for the nicer one, because i just want the drag and drop the components.

any help would be much appreciated.

If you're looking for Swing GUI builder, you're better off using NetBeans (Mattisse) rather than Eclipse since those Eclipse plugins aren't as good as the NetBeans one. MyEclipse has Mattise, BTW.

Nonetheless, my advice is not to use any GUI builder whenever possible. It'll generate boilerplate code that will make your life difficult at later stage.
