Quick Start (SwaRef):Adding a signature field using the web service API

The following Java code example adds a signature field, named SignatureField1, to a PDF document that is based on a PDF file named Loan.pdf. The PDF document that contains the new signature field is saved as a PDF file named LoanSig.pdf. (See Adding Signature Fields.)
/** 
    * 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
