Quick Start (SwaRef): Removing usage rights from a PDF document using the web service API

The following Java code example removes usage rights from a rights-enabled PDF document named LoanUsageRights.pdf. (See Removing Usage Rights from PDF Documents.)
/** 
    * Ensure that you create Java proxy files that consume 
    * the Reader Extensions services  WSDL. You can use JAX-WS to create 
    * the proxy Java files.   
    *  
    * For information, see "Invoking LiveCycle using SwaRef" in Programming with LiveCycle
