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

The following Java web service code example modifies a signature field named SignatureField1 by locking all fields in the form when a signature is applied to the signature field and ensuring that no changes are allowed. After the Signature service returns the PDF document that contains the modified signature field, the PDF document is saved as a PDF file named LoanSig.pdf. (This example overwrites the PDF file that is passed to the Signature service.) (See Modifying 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.
