I'm pretty sure that any book about JSP describes this:
<% response.sendRedirect("/thePageYouWantToRedirectTo.jsp"); %>
If the value starts with a slash, as above, it's interpreted as the
absolute path to the page relative to the server, i.e. you have to
include the context-path if you use this in an application with
a different context path than default:
<% response.sendRedirect(request.getContextPath() +
"/thePageYouWantToRedirectTo.jsp"); %>
If you can use a path that's relative to the current page, i.e. it
doesn't start with a slash, you don't have to worry about the
context path:
<% response.sendRedirect("aPageInTheSameDirectory.jsp"); %>
This, as so much else you can use in JSP, is described in the servlet
specification, since JSP is built on top of JSP. I really recommend
that you get one of the numerous books about JSP, but if you don't
want to (for some obscure reason), you should at least read both the
servlet and the JSP specification:
