Quick Start (SwaRef): Retrieving signature field names using the web service API

The following Java web service code example retrieves the names of signature fields located in a PDF document named LoanSig.pdf. (See Retrieving Signature Field Names.)
/** 
    * Ensure that you create Java proxy files that consume 
    * the Signature services  WSDL. You can use JAX-WS to create 
    * the proxy Java files.   
    *  
    * If you are supplying a set of associated files, add the file name to the BLOB attribute. 
    * The create3DPDF service uses those file names to resolve references from the main assembly file. 
    *    
    * For information, see "Invoking LiveCycle using SwaRef" in Programming with LiveCycle.
