Guida rapida (modalità SOAP): aggiunta di un campo firma a un documento PDF tramite l’API Java

Nell'esempio di codice Java seguente viene aggiunto un campo firma denominato SignatureField1 a un documento PDF basato su un file PDF denominato Loan.pdf. Il documento PDF che contiene il nuovo campo firma viene salvato come file PDF denominato LoanSig.pdf. (Vedi Aggiunta di campi firma.)

     * 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. 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 in the following path:
     * <install directory>/sdk/client-libs/common
     *
     * The adobe-utilities.jar file is in the following path:
     * <install directory>/sdk/client-libs/jboss
     *
     * The jboss-client.jar file is in the following path:
     * <install directory>/jboss/bin/client
     *
     * SOAP required JAR files are 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
