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

The following Java code example verifies a digital signature that is located in a signed PDF document that is based on a PDF file named LoanSigned.pdf. (See Verifying 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.   
    * 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
