Quick Start (EJB mode): Rendering an HTML form using the Java API

The following code example renders an HTML form using the Forms service Java API. A toolbar is added to the HTML form as well as two file attachments. In addition, the user agent value is obtained from the HttpServletRequest object. (See Rendering Forms as HTML.)

/* 
    * 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
