Nathan -
I am now getting the correct content type, but the stylesheet is not
being applied.
I have a web application that uses VVS. I have templates that output
either XML or HTML depending on some conditions. When I output XML, I
include a reference to an XSL stylesheet. The stylesheet is not being
applied. When I save the XML output, put it back on the server and
access it again, the stylesheet is applied. You suggested that the
problem was that the content type was not set correctly, and indeed, the
content type was 'text/html'. I extended the VVS so that I can signal
the VVS as to the content type I wish set in the response from my
application's logic.
I am doing that, and when the template outputs XML, the content
type is 'text/xml', but the stylesheet is still not being applied.
Any other ideas?

That all sounds correct. The only thing i can think of to check on is
whether any content has been committed to the response or if
response.getWriter() is called before the setContentType() call
happens.
http://java.sun.com/products/servlet/2.5/docs/servlet-2_5-mr2/javax/servlet/ServletResponse.html#setContentType(java.lang.String)
Of course, if one of those things is happening, it should not be due
to the VelocityViewServlet. The VVS doesn't send any content or call
response.getWriter() until after the setContentType() method has been
called.
Not sure how much more help i'll be beyond this point...

I believe that I have done what you suggested. I created a class
MyVelocityViewServlet that extends VelocityViewServlet. It contains only
an overridden setContentType(request, response) which pulls an attribute
out of the request and sets the content type of the response based on
the value of the attribute.
Through debugging statements, I can see that the attribute I set is
picked up and the content type is set (to 'text/xml'): nevertheless, the
output of the Velocity template is not being formatted by the stylesheet
at the browser; and, when I look at the page info (in Firefox) the
content type is 'text/html'.
Is there a further step I have to take?

PS - Here is my setContentType
protected void setContentType(HttpServletRequest request,
HttpServletResponse response) {
String ct = (String)request.getAttribute("contenttype");
if(ct != null) {
System.out.println("contenttype found: " + ct);
response.setContentType(ct);
} else {
System.out.println("no contenttype attribute found");
super.setContentType(request, response);
}
}

I tried setting the content type from the template and no joy. I
also tried setting the content type in the response
from my logic before passing the request off to the
VelocityViewServlet.
Also no go. I suppose that is because either a) the handoff to the
ViewServlet is a forward so the View servlet doesn't even see my
partial
response, or b) the ViewServlet explicitly sets the content type.
Since
a) is more probable, I will probably have to extend the ViewServlet.
