How to redirect to error page in servlet?

Question

I am writing the servlet , in case of exception I am redirecting to my customized error page for that i have done like this.

In web.xml

Answer 1

You have handled the Exception in your doPost() using ,

try{
       //Here is all code stuff
       Throw new Exception();
}catch(Exception e){
         e1.printStackTrace();    
}

try and catch blocks. so the errorPage.jsp will not be invoked. is invoked for unhandled exceptions
