Quick Start (SOAP mode): Modifying a signature field using the Java API

The following Java 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.)

/* 
    * 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
