Quick Start: Optimizing performance using the Java API

The following code example optimizes performance by setting the caching, standalone, and linearized options. A linearized file is optimized for delivery on the web. (See Optimizing the Performance of the Forms Service.)

/*

 * 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
