I will integration Glassfish 4.1 on Eclipse Mars. But I received an error when glassfish started.
"Key value shall not be null."
I could not find resolition anywhere. But after one day found out resolition. There are a few missing starting parametres on Glassfish and Eclipse.
Here is the solution : Adding that line to domain.xml
-Duser.language=en and that line to eclipse.ini
-Duser.language=en solved the problem.
Thanks
