Re: null pointer exception problem
This is an HTML page. Not an application
Re: null pointer exception problem
Your error description doesn't really help much.
What part of web applications are you studying?
Like, are you doing pure servlets, or jsp or struts? How did you setup your environment for it?
Also, where are you getting the null pointer exception?
