Today, i'm using JSP to perform the view. I also use JSP as controller.
Although view and controller are separated, I'm looking for a best way to do
this via XML/XSLT.
My approach is :
A request is sent to the web server :
- Controller (JSP) handles the request
- Controller (JSP) asks data to the model
- Model furnishes Datas (XML) to the controller
- The controller modifies data to perform request actions
- The controller forwards data modified to the view using XSL / XSLT
Here is an example, exactly what I want to do, a JSP handles the request,
performs some actions and sends data rendered by XSL :
<%@ page contentType="text/xml" %>
<?xml:stylesheet type="text/xsl" href="myxsl.xsl" version="1.0"
encoding="ISO-8859-1"?>
<doc title="foo">
<description>
I'm a JSP. I'm processing the request.
<description>
<%
while(request.getParameterNames().hasMoreElements())
{
%>
<item><%=(String)request.getParameterNames().nextElement()%></item>
<%
}
%>
</doc>
But I want to perform the XSL Transformation on the server side to have the
full control using something like :
StreamSource source = new StreamSource( THE XML response performed by
the JSP controller );
StreamSource stylesheet = new StreamSource("D:\\Dev\\web\\data.xsl");
// Use a Transformer for output
TransformerFactory tFactory = TransformerFactory.newInstance();
Transformer transformer = tFactory.newTransformer(stylesheet);
StreamResult result = new StreamResult(out); // out : to the client web
borwser
transformer.transform(source, result);
I don't know how to forward the XML response of my JSP to the servlet doing
the XSL Transformation. Have an idea ?
I have never seen example using JSP / XML / XSLT that way. Am I going in a
wrong way ?
It sounds like to me because the view is completly separated from the rest
of the application.
