The jiveHome directory is a directory containing configuration files, logs, data (for the embedded database) and other items the product needs to run correctly. Most importantly, the jive_config.xml file is located there - this is the central configuration file for the product.
You must tell the Jive classes where the jiveHome directory exists. You can do this by setting the "jiveHome" property in a variety of ways. For more information, please read the url http://www.jivesoftware.com/builds/docs/latest/install-guide.html#appserverinstallation guide[/url].
The jiveHome directory should be kept outside of the Jive Forums or Jive KB web application. This is because you may want to rebuild and redeploy your Jive war and when that happens the application server will delete the older war and deploy the new.
