Quick Start (SOAP mode): Handling a form containing a calculation script using the Java API

The following code example processes a form that contains a calculation script and writes the results back to the client web browser. (See Calculating Form Data.)

/* 
    * This Java Quick Start uses the following JAR files 
    * 1. adobe-forms-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-3.2.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) 
    *  
    *  (Because Forms quick starts are implemented as Java servlets, it is  
    *  not necessary to include J2EE specific JAR files - the Java project 
    *  that contains this quick start is exported as a WAR file which 
    *  is deployed to the J2EE application server) 
    *   
    *  These JAR files are located in the following path: 
    * <install directory>/sdk/client-libs/common 
    *  
    * For complete details about the location of these JAR files,  
    * see "Including AEM Forms library files" in Programming with AEM forms
