Quick Start (Java SwaRef): Unlocking an encrypted PDF document using the web service API

The following Java code example unlocks a password-encrypted PDF document named EncryptLoan.pdf. (See Unlocking Encrypted PDF Documents.)
/** 
    * 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.
