Quick Start (SwaRef): Converting a PDF document to PostScript using the web service API

The following Java web service example converts a PDF document called Loan.pdf to a PostScript document called Loan.ps. (See Converting PDF Documents to PostScript.)
/** 
    * Ensure that you create Java proxy files that consume 
    * the Convert PDF services  WSDL. You can use JAX-WS to create 
    * the proxy Java files.   
    *    
    * For information, see "Invoking LiveCycle using SwaRef" in Programming with LiveCycle.
