So I am creating a game in Java, the game works fine when I run it in Eclipse but when I export it it does not draw anything on the screen.
I added a try and catch for nullpointerexceptions but the game does not throw any nullpointerexceptions.
What is the problem?
The game seems to be finding all the images & resources since it does not throw any NullPointerExceptions...

My dynamic web project has a java class that captures a session variable with the following code.
HttpSession LoginSession = request.getSession();
String VAR = LoginSession.getAttribute("myVar").toString(); //This is the row 127
If i test the app in local (Mac + Java 1.8 + Tomcat 8) all works. In my remote cloud server (Ubuntu 14.10 + Java 1.8 + Tomcat 8) all works, except this class, that has this code. I copy the complete error here. Note that the row 127 of the error message is the second row of the previous code; and, if i comment this row with // and assign a fix variable all works. So, the problem is that 127^ row.
