The following Java code example represents the Java servlet
that invokes the FirstAppSolution/PreLoanProcess process.
/*
* 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
*
* For complete details about the location of these JAR files,
* see "Including LiveCycle library files" in Programming with LiveCycle
