When starting glassfish server, if you get
"Unable to start server due following issues: java.lang.NullPointerException" exception, it is probably because of the localization settings of eclipse. To change eclipse’s localization settings:
- Open eclipse.ini file which is located in your eclipse installation directory (in the same folder with eclipse.exe).
-Duser.language=enin the bottom of your eclipse.ini.
- Restart eclipse.
There is a parallel problem for netbeans. If you get: “GlassFish Server Server start failed. Cant create start proccess” in netbeans, consult: https://madvens.wordpress.com/2013/07/05/netbeans-glassfish-problem-solution/
