Java application as NT Service

TestService is a small Java service that handles all signals received from the Service Control Manager. This service does nothing except that it logs a message in the service-log.txt file every 15 seconds. This file will appear in you current directory or in a directory specified in by InstallServiceTest.java. If this directory requires certain user access permissions you will have to specify username and password for the service (check InstallServiceTest.java for details).
Note that after it has been installed by the InstallServiceTest application, test service won't start automatically. To start or stop the service use Services applet from the Control Panel (TestService will should appear as "JObjects JST - Service example"). The information about received signal will be logged in the service-log.txt.
