The following Java code example encrypts a PDF document
named Loan.pdf with a certificate named Encryption.cer.
The encrypted PDF document is saved as a PDF file named EncryptLoanCert.pdf.
(See Encrypting PDF Documents with Certificates.)
/**
* Ensure that you create Java proxy files that consume
* the Encryption services WSDL. You can use JAX-WS to create
* the proxy Java files.
*
* For information, see "Invoking LiveCycle using SwaRef" in Programming with LiveCycle.
