The following Java code example verifies multiple digital
signatures that are located in a signed PDF document that is based
on a PDF file named LoanAllSigs.pdf. The verification time
is set to current time and the revocation checking option is set
to best effort. (See Verifying Multiple 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
