Use NetBeans 5.5.1 with GlassFish v2 (SJS AS 9.1)
By pelegri on Jan 18, 2007
GlassFish v2 stopped working with NetBeans 5.5 after v2 b26 due to several changes including this one. The solution is to use the new release of NetBeans, 5.5.1, available from the NB Downloads page. This release is not yet final but it is very stable as only incorporates selected bug fixes.
