Hi All,
I have a requirement that a jsf page needs to be launched from a custom thin client in user browser (thin client does a http post). Since the jsf page may be invoked multiple times, I use a jsp to redirect to the jsf page with params on url. In jsp I do a session invalidation. The jsp code is below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@page session="true" %>
<%
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
session.invalidate();
String outcome = request.getParameter("outcome");
String queryString = "outcome=" + outcome ;
response.sendRedirect("./faces/MyPage.jspx?" + queryString);
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252"></meta>
<title>title here</title>
</head>
<body></body>
</html>
My jsf page uses mutiple drop down items with autoSubmit enabled. I set the params on session when the form first inits and then use it from there when an action button is ultimately clicked by user. Following is the code I use to get the param in jsf backing bean constructor:
FacesContext ctx = getFacesContext();
Map sessionState = ctx.getExternalContext().getSessionMap();
outcome = (String)sessionState.get("outcome");
if(outcome == null) //if not on session, get from url
outcome = (String)JSFUtils.getManagedBeanValue("param.outcome");
This way I can get the param even after multiple autoSubmits of drop downs.
My problem is that I cannot have parameters show up on browser address bar. I need a way so that the parameters can be passed to the jsp page. I cannot post direct to jsp from thin client since I need the jsf page to have a new session each time the client launches user browser. This is imp due to the above code snippet on how I use params in the jsf page.
Is there nay way to use a post when doing a sendRedirect so that I do not have to pass params on url? I cannot use forward since when an autoSubmit fires on jsf page, it causes the browser to refresh the jsp page instead.
Is there any better way to handle the jsf page itself so that I don't have to rely on storing params on session between successive autoSubmit events?
