Quick Start (SOAP mode): Verifying a digital signature using the Java 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. The verification time is set to current time and the revocation checking option is set to best effort. (See Verifying Digital Signatures.)

    * This Java Quick Start uses the following JAR files 
    * 1. adobe-signatures-client.jar 
    * 2. adobe-livecycle-client.jar 
    * 3. adobe-usermanager-client.jar 
    * 4. activation.jar (required for SOAP mode) 
    * 5. axis.jar (required for SOAP mode) 
    * 6. commons-codec-1.3.jar (required for SOAP mode) 
    * 7.  commons-collections-3.1.jar  (required for SOAP mode) 
    * 8. commons-discovery.jar (required for SOAP mode) 
    * 9. commons-logging.jar (required for SOAP mode) 
    * 10. dom3-xml-apis-2.5.0.jar (required for SOAP mode) 
    * 11. jaxen-1.1-beta-9.jar (required for SOAP mode) 
    * 12. jaxrpc.jar (required for SOAP mode) 
    * 13. log4j.jar (required for SOAP mode) 
    * 14. mail.jar (required for SOAP mode) 
    * 15. saaj.jar (required for SOAP mode) 
    * 16. wsdl4j.jar (required for SOAP mode) 
    * 17. xalan.jar (required for SOAP mode) 
    * 18. xbean.jar (required for SOAP mode) 
    * 19. 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
