Каждый WYSIWYG генерит свой код. XML формы из NetBeans вы нигде больше использовать не сможете.
Советую WindowBuilder Pro для Eclipse + MiGLayout, а код уже можно правиль в идее. Там XML никакого нет.

ErikIПонятно, что формы из NetBeans не судьба импортировать в Idea. Проект полностью готов, так что придется использовать NetBeans. Могу добавить что используется AbsoluteLayout. Большое спасибо.
http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.wb.doc.user%2Fhtml%2Ffaq.html Can WindowBuilder Pro edit windows created with JBuilder, VA Java, NetBeans, VisualCafe, etc.?

Yes. Most GUI builders in the world will only read and write the code that they themselves create. WindowBuilder Pro is an exception to that rule. It can read and edit not only the code it creates, but also a great deal of code generated by other GUI builders (>95%). We have had very good success with code generated by JBuilder, NetBeans, Visual Cafe, VA Java, the Eclipse VE, etc. If you come across a case that does not work, send it to us for analysis. The more broken examples that we can "fix", the better WindowBuilder Pro will get in the long run (and the better chance you will have of salvaging your old code as-is). Note that WindowBuilder Pro will edit any existing code in place without changing its formatting. Any new widgets will be created using WindowBuilder Pro's own code generation preferences.
