Don't make a JSP that build the XML, while treat your JSP as a simple
XML file, then delegate to the XSL file making the JSP.
To be clearer:
Make a JSP that receives the request
then call from it the servlet (or jsp) that invokes
Transformer.transform() whose source is just such an XML file:
<doc title="foo">
<description>
I'm a JSP. I'm processing the request.
<description>
<%
while(request.getParameterNames().hasMoreElements())
{
%>
<item><scriptlet><%=(String)request.getParameterNames().nextElement()%
></scriptlet></item>
<%
}
%>
</doc>
Your data.xsl will have to be changed to include
at the head:
<%@ page contentType="text/xml" %>
and somewhere else:
<xsl:template match="scriptlet">
<xsl:apply-templates/>
</xsl:template>
> 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.

> - 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
