System.out.println OR out.println

When u get any error in JSP this first step to find the problem is to give System.out.println(If you want to see the output in console) OR you can use out.println(If you want to see the output in the screen itself). Try to give as much as possible.
Right click on the jsp you might get a null pointer exception in the view source.
