OpenOffice UNO export PDF help needed

[Sells, Fred]

I've geen googling for 3 days now, and cannot find out how to do this.

I'm trying to use OpenOffice 2.0 and UNO to generate PDF documents.  I'm
using windows, but will have to make it work under Linux for production.
I've been able to set the parameters and call the exportToPdf method, but
the exported file is not PDF but an .odt document,  I can change suffix from
pdf to odt and double click on it and open it as openoffice.  The project is
sort of a custom mail-merge, but there is little data used to produce a
lengthy contract and attachments.  The whole thing needs to be done via a
cgi script or a servlet.

below is a java code snippet, submitted with apologies,  I'm using that
rather than python because I found better examples and my java IDE helps me
out.  I originally started out to do python, and will eventually shift back
to it once I get this working


 public void writePDF(XTextDocument doc, String stringUrl) {
        String stringConvertType ="PDF Creator";// args[ 1 ];
         PropertyValue propertyvalueHidden[] = new PropertyValue[ 0 ];
         XStorable xstorable =( XStorable ) UnoRuntime.queryInterface(
XStorable.class, doc );

           // Preparing properties for converting the document
           PropertyValue propertyvalue[] = new PropertyValue[ 2 ];
           propertyvalue[ 0 ] = new PropertyValue();
           propertyvalue[ 0 ].Name = "Overwrite";
           propertyvalue[ 0 ].Value = new Boolean(true);
           propertyvalue[ 1 ] = new PropertyValue();
           propertyvalue[ 1 ].Name = "Filter";
           propertyvalue[ 1 ].Value = "writer_pdf_Export";
           //propertyvalue[ 1 ].Value = "impress_pdf_Export";  //also tried
"PDF Creator"
           xstorable.storeToURL( stringUrl+".pdf", propertyvalue );  //also
tried storeAsUrl, same result
