Quick Start (EJB mode): Handling HTML forms submitted as XML using the Java API

The following code example handles an HTML form that is submitted as XML data. The content type value passed to the processFormSubmission method is CONTENT_TYPE=application/x-www-form-urlencoded.The values that correspond to the fields named mortgageAmount, lastName, and firstName are displayed. A user-defined method named getNodeText is used in this quick start. It accepts an org.w3c.dom.Document instance and a string value that specifies the node name. This method returns a string value that represents the value of the node. (See Handling Submitted Forms.)

/* 
    * This Java Quick Start uses the following JAR files 
    * 1. adobe-forms-client.jar 
    * 2. adobe-livecycle-client.jar 
    * 3. adobe-usermanager-client.jar 
    *  
    *  (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 LiveCycle library files" in Programming with LiveCycle
