Hello,

in my applikation I create a DOM-Tree dynamically (not from a XML-file)
representing the data.

Also, I have a XSL-file representing the layout.

Now I would like to create a PDF-file from these to sources.
But the only way I see by now is to create PDF from an XML-file together
with the XSL.

I could think of something like this:

 ...
 Document theDoc = ....
 DocumentInputSource theDISource = new DocumentInputSource( theDoc );

 Driver driver = new Driver(theDISource ,
                                    new FileOutputStream("pdfFile_Name") );
 driver.setRenderer(RENDER_PDF);
 driver.run();
+++++++++++++++++++++++++++++++++++++++++++++


but how can I include the layout-information?

If I run to above example I get the following output/exception

The used Document is correct and works together with the XSL correctly (by
now I do create
the Document from a XML-file, but i plan to create it dynamically as told
above)

Thanks,
Michael
