Very good idea. What I've done is made a function which works with POST and
GET requests, and is used as follows :
<%
// Post request
Hashtable p = new Hashtable();
p.put("string", "backwards");
HttpForwardUtil.include(response, "POST",
"http://java.sun.com/cgi-bin/backwards", p);
// Get request
HttpForwardUtil.include(response, "GET", "http://www.yahoo.com", null);
%>
This is *almost* the functionality I'm looking for. When you do something
like this :
<B>This is my JSP file</B>
<jsp:forward page="http://someLOCALservlet">
<B>More JSP code</B>
the only thing that gets sent to the browser is the data from
http://someLOCALservlet, not the 2 other lines. So what I'm looking for is
if I type in :
<B>This is my JSP file</B>
<% HttpForwardUtil.forward(response, "GET", "http://www.yahoo.com", null);
%>
<B>More JSP code</B>
All I'll see is Yahoo. I tried putting a response.reset() before the call,
and a reponse.flushBuffer() after the call (thinking that it would commit
the call and send it) but I still get the other JSP code. I can work around
this easily using the include as opposed to the forward, but if anyone has
any input, that'd be great.
If there's anyone that could use this code please let me know personally,
and I can send it. It was a bit too long for the listserv.
Take it easy,
Roy
