uri-include calling servlet: problems

["Gregory J. Grubbs" <bu...@hoochiepep.com>]

Robin's explanations have been most helpful.  I now have one of my servlets being called from an XSP page and returning a reasonable result.  The
solution seems very elegant and flexible to me.

There are however two things which bother me about the solution:

1) To pass the data from my HTML form using the method suggested in the FAQ, I must alter the method from POST to GET, then use code like the
following:
 <util:include-uri>
    <util:href>
       <xsp:expr>"http://localhost/servlet/myServlet?" + request.getQueryString()</xsp:expr>
    </util:href>
 </util:include-uri>

Is there any way to continue using the POST method from forms, avoiding the encoded URL being shown in the browser when the result returns?

2) I want my middleware servlet to return a complete XML response, including a specification of the stylesheet to apply.  But if the servlet
returns the <?xml-stylesheet ... > PI, that PI will include inside the <page> tag... and thus confuse Cocoon, which throws the trace:

org.apache.cocoon.processor.ProcessorException: Could not associate stylesheet to document:  no matching stylesheet for: explorer

Is there any clever way of applying a stylesheet specified by the servlet's return value?
