In one of my JSP pages (ErrorPage.jsp) I have the

//Lot's more code

It works, but prints out unnecessary html before it
forwards. But if I uncomment "return" it stops
working. I get
HTTP 500 - Internal server error
What could that be? In the tomcat console window, I
get no indication that something is not right.
First you still should be presenting a well formed HTML page to the
browser. I think I'm correcting in stating that <META ...> should
exiting inside <HEAD>, but you still should emit
</HEAD><BODY></BODY></HTML>.
Second are you sure you want to do your HTTP redirect like this ?
Conceptually by the time you are rendering a JSP page your that Servlet
has made a decision that this JSP page (and therefore this View) is the
correct one the user should see. I am presuming that you might not have
any customer Servlet infront of this JSP page and are using the
defaultServlet to get there. Maybe its worth you creating a Servlet and
moving the Java Code logic into that. Then doing a "forward" to the JSP
page you wish to render, or setup a HTTP redirect to force the browser
to goto another URL.
My thoughts.
I'm not sure if return is right or wrong here from a specification
standpoint.
