/**
 * Activates XPA Diagnostic logging.
 * <p>
 * This sample requires JDK 1.4 or higher.
 * <p>
 * This application demonstrates how to configure the
 * JDK 1.4 java.util.logging package to receive diagnostic logging
 * messages that XPA generates. If you don't configure logging in some
 * way, log messages are sent to System.err.
 * <p>
 * There are other logging packages you can configure for XPA,
 * such as Log4j. 
 * Consult the documentation accompanying those packages and the 
 * <a target="_blank" href="http://jakarta.apache.org/commons/logging/">
 * Jakarta Commons Logging package</a>.
 * <p>
 * To use this application, edit the file "Sample.properties" 
 * to point to your Ultraseek server.
 *
 * @since XPA2.2
 * @requires JDK 1.4
