Re: XSL/PDF

In your Struts Action.ActionForward class, if you call
"response.reset();" at the beginning it seemed to work
for me (erases the first of the two calls IE made).

However, I suspect that would then render Mozilla and
Netscape browsers inoperable because they don't make
multiple calls.  Perhaps best to find out the browser
the client is using first?  Main thing is make sure
your changes don't affect users of other browsers that
were programmed correctly.

Or, if possible, better to design the code such that
even if it calls it multiple times everything will
still work fine.  If IE is a sluggish browser because
it insists on requesting & generating reports multiple
times, then so be it--recommend to your users other
browsers for better speed!

Other possibilities:

Re: XSL/PDF

Hmm...

Calling Response.setContentType(String) shouldn't cause the servlet 
container to re-execute a call to ActionServlet.doGet(...); have you 
determined why this is occuring?

Fortunately, you have options if you cannot find a solution.  Here are some:

(1) Create a servlet that generates the PDF.  Forward to the servlet in 
your Action class.

(2) Create the same servlet mentioned above and call it directly, 
bypassing Struts.

(3) Generate the PDF within the Action class, and instead of returning 
it as the contents of the HTTP Response, save the PDF to the file system 
and return an HTTP redirect to the PDF.

Let me know if you have questions on any of the above.
