I have the following in a jsp file
<%@ include file="applicationimports.inc" %>
<%@ include file="connection.inc" %>
<%@ include file="sessioncheck.inc" %>
<%
CustomerHTTPManagementScreen customerHTTPManagementScreen =
(CustomerHTTPManagementScreen)session.getAttribute("customerHTTPManagementScreen");
if( customerHTTPManagementScreen == null )
{
response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("main.jsp"));
return;
}
if( request.getParameter("submit") != null )
{
if( request.getParameter("submit").equals("Modify Order") )
{
response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("orderentry.jsp?OpenOrder="
+ customerHTTPManagementScreen.getOrderHeaderID()));
return;
}
String key;
Hashtable parameters = new Hashtable();
for( Enumeration e = request.getParameterNames(); e.hasMoreElements()
;)
{
key = (String)e.nextElement();
parameters.put(key, request.getParameter(key));
}
customerHTTPManagementScreen.processPerformed( new
ProcessEvent(request.getParameter("submit"), parameters) );
}
response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("customer.jsp"));
%>
This file handles the processing for its connected jsp page (it is directed here to do
the processing).
As you can see near the end is calls processPerformed, that sends the submit to the
parent class. The parent class then does most of the process, then it is redirected
back to the connected parent jsp (in this case custoner.jsp)
What I want to do here is get the submit of "Modify Order" to be handled by my web
application. My web application main class is tmWebApp, it already has response and
request available to it, so I could call the redirect from there.
The problem is, this jsp file will then try to redirect the page again on the last
call. How do I determine if the application already redirected this?
Is my only option to catch an IllegalStateException or check isCommited()? Not as if
that is a bad idea, but would there be anything else here that would get in my way,
like is there anything else that would set that response to be commited?
