Invoking Human-Centric Long-Lived Processes

 /*
     * This Java Quick Start uses the following JAR files
     * 1. adobe-livecycle-client.jar
     * 2. adobe-usermanager-client.jar
     *
     * (Because this  quick start is implemented as a Java servlet, 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
     *
