There is no issue with the O.S as NetBeans IDE 5.5.1 is compatible with Windows XP, Windows Vista, Windows 7, Linux, Solaris and Mac OS. The syntax you have mentioned about the exception message reflects that your NetBeans IDE 5.5.1 setup is incomplete (some setup files missing) making it not worthy for installation. Uninstall the present setup and try installing the entire setup after downloading from official website.

If the troubleshooting is still repeated then uninstall your present GlassFish and install GlassFish v2 as it is recommended to run GlassFish v2 in order to work with NetBeans IDE 5.5.1 rather than any other versions of GlassFish. Also it makes it easier to communicate with EJBs from the NetBeans platform. After installing GlassFish v2 install NetBeans IDE 5.5.1 and restart your computer. GlassFish v2 is not compatible with NetBeans IDE 5.5.

If the problem is unsolved after performing the above steps then try using some other versions of NetBeans such as NetBeans6.0, 6.1 etc. The later versions of NetrBeans after NetbBeans 5.5.1 have more bug fixes, features and many modules. First uninstall the present version from your computer then install the new version.
