Quick Start: Rendering a form based on fragments using the Java API

The following code example renders a form that is based on fragments. The name of the form design is POFragment.xdp and it is located in the LiveCycle ES repository (the XDP file is stored in a folder named FormsFolder located in the repository). Also the fragments that the POFragment form references must also be located in the repository. (See Rendering Forms Based on Fragments.)

/*

 * 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>/Adobe/LiveCycle8/LiveCycle_ES_SDK/client-libs

 * 

 * For complete details about the location of these JAR files, 

 * see "Including LiveCycle ES library files" in Programming with LiveCycle ES
