I've grown to prefer NetBeans over Eclipse, and I've been wondering similar thoughts. One thing that does work is developing your JPA Entities in NetBeans, then switching to Eclipse to continue. I've also tried starting a generic JSF project in NetBeans and adding the ADF Faces component libraries. This also sort-of works, but you don't get the nice WYSIWYG visual design tools. Nope - I guess it is JDeveloper or OEPE for me. Strange - since Oracle is primary developer of NetBeans you would think they would add a plugin to it. Goes with ADF being a "mature" product, I guess.
