Hi all, My servlet has the following code in its doGet() method. String adr = "/xxx/xxx.jsp"; ServletConfig sConf = getServletConfig(); // line1 ServletContext sCont = sConf.getServletContext(); //line2 RequestDispatcher dispatcher= sCont.getRequestDispatcher(adr);//line3 line 1 seems to work fine. (I originally had print statement between each line.. ) but line2 returns null.. 'cos I get NullPointerException at line 3. I am don't know what is wrong... HELP!!!

Hi sean, Can you be more specific about the servlet engine you are using. Some servlet engine doesn't seem to implement the JSDK specs completed. getServletContext() is one of the methods that is primarily based on the servlet engine. Satish

Hi sean, If we had overridden init(ServletConfig config)throws .. {...} method, then we shouldn't forget to call super.init(config); If we miss this line, then latter our servlet can't get hold of ServletConfig object and we will get NullPointerException. Is this your case? regds maha anna [This message has been edited by maha anna (edited December 21, 2000).]
