The following Java code example removes a digital signature
from a signature field named
SignatureField1
. The name of
the PDF file that contain the signature field is
LoanSigned.pdf
.
(See Removing
Digital Signatures.)
/*
* This Java Quick Start uses the SOAP mode and contains the following JAR files
* in the class path:
* 1. adobe-signatures-client.jar
* 2. adobe-livecycle-client.jar
* 3. adobe-usermanager-client.jar
* 4. adobe-utilities.jar
* 5. jboss-client.jar (use a different JAR file if the forms server is not deployed
* on JBoss)
* 6. activation.jar (required for SOAP mode)
* 7. axis.jar (required for SOAP mode)
* 8. commons-codec-1.3.jar (required for SOAP mode)
* 9. commons-collections-3.1.jar (required for SOAP mode)
* 10. commons-discovery.jar (required for SOAP mode)
* 11. commons-logging.jar (required for SOAP mode)
* 12. dom3-xml-apis-2.5.0.jar (required for SOAP mode)
* 13. jaxen-1.1-beta-9.jar (required for SOAP mode)
* 14. jaxrpc.jar (required for SOAP mode)
* 15. log4j.jar (required for SOAP mode)
* 16. mail.jar (required for SOAP mode)
* 17. saaj.jar (required for SOAP mode)
* 18. wsdl4j.jar (required for SOAP mode)
* 19. xalan.jar (required for SOAP mode)
* 20. xbean.jar (required for SOAP mode)
* 21. xercesImpl.jar (required for SOAP mode)
*
* These JAR files are located in the following path:
* <install directory>/sdk/client-libs/common
*
* The adobe-utilities.jar file is located in the following path:
* <install directory>/sdk/client-libs/jboss
*
* The jboss-client.jar file is located in the following path:
* <install directory>/jboss/bin/client
*
* SOAP required JAR files are located in the following path:
* <install directory>/sdk/client-libs/thirdparty
*
* If you want to invoke a remote forms server instance and there is a
* firewall between the client application and the server, then it is
* recommended that you use the SOAP mode. When using the SOAP mode,
* you have to include these additional JAR files
*
* For information about the SOAP
* mode, see "Setting connection properties" in Programming
* with AEM Forms
