Subject Re: Use of return statement in servlet.
Date Fri, 31 Oct 2003 07:55:53 GMT
Thanks for the reply
I want the browser to point to the query page if user did not provide enough
data or an error happens like database connection is not available. I want
user to re enter data or wait for some time .  So I dont want to use
"requestDispatcher.forward()"  method or redirect to an error page. I want
to know is there any problems in using the return statement in servlets/jsp.
