Hi Stanislav,
  Use these lines to avoid the NullPointerException

import javax.servlet.ServletContext;
import javax.servlet.http.HttpSession;


   HttpSession ses = request.getSession();
   ServletContext cfg = ses.getServletContext();

Hope this piece of code helps you,

Thanks & Bye,Ganesh.K

Hi,

Use 
ServletContext sc = GenericServlet.this.getServletContext(); // as this is a 
method of GenericServlet.

ServletContext sc = this.getServletContext();

This means no need to give servlet. getServletContext();

I am surprise why are u using servlet.get*

RE: ServletContext NullPointerException

2005-12-27 Thread Rakesh.Bhat 
Hi,

you can check your code I marked with arrows. Any way I will explain here also.
See you have created a Connection obj called con and initialized it with 
null.however you are inside creating one more object on Connection called conn2 
and intilaiting it with method getConnection.
And calling createStatement using conn object of Connection which is 
initialized to null.That is a reason u r getting NUllPointerExp

Check your code with arrows.
