Quick Start: Invoking a service using SwaRef in a Java project

The following Java code example invokes a process named MyApplication/EncryptDocument from a Java project. This Java project using proxy classes that were created using JAX-WS and SwaRef as the encoding type. (See Invoking LiveCycle using SwaRef.)

An unsecured PDF document based on a PDF file named Loan.pdf is passed to the LiveCycle process using SwaRef. The encrypted PDF document is saved as a PDF file named EncryptedDocument.pdf.

/** 
    * Ensure that you create Java proxy files that consume 
    * the the LiveCycle service WSDL. You can use JAX-WS to create 
    * the Java proxy files.   
    *    
    * This Java quick start uses SwaRef to invoke a short-lived process named 
    * EncryptDocument. For information, see  
    * "Invoking LiveCycle using SwaRef" in Programming with LiveCycle.
