You have to add a "return;" after the forward() call. There's no magic in Java
that
let's it figure out by itself that it should not continue when the forward()
call
returns.
In a JSP page, using <jsp:forward>, there *is* some magic though; the
<jsp:forward>
tag tells the JSP container that the rest of the page should be ignored (using a
special return code, see the JSP 1.1 spec for details). But if you forward with
regular Java code, you have to be your own magician.
