The following Java code example converts a PDF document
called Loan.pdf to a set of JPEG files and stores them in
the C:\Adobe directory. Each file is named tempFile[index].jpg,
where the first image file is named tempFile0.jpg. (See Converting PDF Documents to Image Formats.)
/**
* 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.
