# Introduction

The Java sample programs demonstrate how to use the Java implementation of XML Export. The sample code is intended to provide a starting point for your own applications or to be used for reference purposes. You can also test these sample programs with the sample files provided in `install\testdocs`.

The source code for the programs is in the directory `javaapi/sample`. Included alongside the source code are compiled `.class` files, and Batch (`.bat`) and C Shell (`.csh`) files that help run each program.

The sample programs pass license information to KeyView through the `XmlExport` constructor. This is the method recommended by Micro Focus. Before the sample code can be compiled, you must replace the placeholders `YOUR_LICENSE_ORGANIZATION` and `YOUR_LICENSE_KEY` with your license information.

The compiled `.class` files that are supplied in the SDK have an embedded trial license, which expires approximately five months after release. If the environment variables `KV_SAMPLE_PROGRAM_LICENSE_ORGANIZATION` and `KV_SAMPLE_PROGRAM_LICENSE_KEY` are set then those values are used instead, so that you can use the programs after the embedded trial license has expired, and test or troubleshoot with your own license.
