Hi,
I'm getting into trouble porting a webapp to jahia using a MVC architecture
(but no framework like Struts...).
The concept is simple, using complementary path:
1. A form post to a servlet with a path and a complementary path:
-----------------------------------------------------------------------
(...)
<form name="formulaire" method="post"
action="<%=response.encodeURL(request.getContextPath() +
"/ElmtCtrl/EventPreview")%>" onSubmit="return verifierFormulaire();">
(...)
The path to the servlet controler is "ElmtCtrl" and the complementary path
(next view) is /eventPreview
2. The servlet controler analyse the complementary path, then create the
model as a bean, then forward to the next view:
-----------------------------------------------------------------------
(...)
protected void doPost(HttpServletRequest arg0, HttpServletResponse arg1)
throws ServletException, IOException {
RequestDispatcher dispatcher=null;
ServletContext context = getServletContext();
try{
// get the name of the view analysing the complementary path
String name = arg0.getPathInfo();
name = name.substring(1);
(...)
// Create model as a javabean
if ("NewsPreview".equals(name)){
NewsModel news = (NewsModel)session.getAttribute("news");
(...)
}
else if ("EventPreview".equals(name)){
EventModel event = (EventModel)session.getAttribute("event");
(...)
}
else throw (new Exception());
// Forward to the next view...
dispatcher = context.getNamedDispatcher(name);
if (dispatcher == null) throw (new Exception());
} catch(Exception e){
log("Exception in ElmtCtrl.doPost()");
dispatcher = context.getNamedDispatcher("ErrorView");
} finally {
// Forward is here...
dispatcher.forward(arg0, arg1);
}
}
(...)
This works fine into TOMCAT but into a jahia portlet I got the error
message:
"Error while retrieving application j2EE news and events for RPN"
I'm wondering if I need to write:
dispatcher = context.getNamedDispatcher(arg1.encodeURL(name));
or something like that because Web application Developer Guide show page 24
it's the good maner to do with HTTP Redirects from web applications...
Any help is very welcome!
Thanks.
