Quick Start: Invoking a service using Java proxy files and Base64 encoding

The following Java code example invokes a process named MyApplication/EncryptDocument using Java proxy files created using JAX-WS and Base64 encoding. (See Invoking LiveCycle using Base64 encoding.)

An unsecured PDF document based on a PDF file named Loan.pdf is passed to the AEM Forms process. The process returns a password-encrypted PDF document that 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 Base64 to invoke a short-lived process named 
    * EncryptDocument. For information, see  
    * "Invoking LiveCycle using Base64" in Programming with AEM forms.
