Hi Mourouganandame,
I happen to know that the Struts 2 plugin works even for NetBeans 6.5 Beta because I tested it yesterday
Maybe it's not the most mature plugin regarding the features but besides this it does its job very well!
You should simply give it a try and perhaps the plugin will become mature with the final 6.5 release.
