Caused by: java.lang.NullPointerException

At line 46 of SeverNewsPlayerListener.java something goes wrong. It's likely one of the variables used in the line is not instantiated properly and is still null.

 

I already check this.. but this isnt the problem

 

We need some source code to diagnose the exact problem. NullPointerException only tells us that you tried to use a null reference as if it were an actual object (not null).

I don't believe you

line 46 of ServerNewsPlayerListener:

Code:

if(this.plugin.blNotifyOnPlayerJoin){

If I'm wrong, please point out where you initialise the plugin variable.
I don't see you defined a constructor for the listener either, which you kinda need if you want to make the variable point to your running plugin-object.
