Quick Start (SwaRef): Removing a digital signature using the web service API

The following Java code example removes a digital signature from a signature field named SignatureField1. The name of the PDF file that contains the signature field is LoanSigned.pdf. (See Removing Digital Signatures.)
/** 
    * Ensure that you create Java proxy files that consume 
    * the Signature services  WSDL. You can use JAX-WS to create 
    * the proxy Java files.   
    *    
    * For information, see "Invoking LiveCycle using SwaRef" in Programming with LiveCycle
