Re: Redirecting the browser to another page

    How do you close the output stream before redirecting?  The whole
point is that the redirect has to happen before the commit.   Otherwise
the response headers have been sent, and so the redirect response code
cannot be sent.

    Just put the tag at the start of the jsp file.

<%@page ...
%><%@ taglib uri="http://jakarta.apache.org/taglibs/response-1.0"
prefix="response"
%><response:sendRedirect><response:encodeRedirectUrl>"http://somepage.jsp"</response:encodeRedire
ctUrl></response:sendRedirect>

etc . .
