Quick Start: Rendering an HTML form that uses a CSS file using the Java API

The following code example renders an HTML form using the Forms ES service Client API. The name of the custom CSS file that is referenced is custom.css. (See Rendering HTML Forms Using Custom CSS Files.)

/*

 * 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
