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.
