Unwanted pop-up dialog boxes

If you are using the licensed ILOG products from within a web server, and do not want the server to display pop-up dialog boxes (for example, because the console of the web server is unattended, or because some web servers do not exit cleanly after an AWT/Swing window has been shown), you can prevent JLM from displaying them by setting the system property java.awt.headless=true. If this is set, JLM will write any possible error messages to the log files of the web server, instead of displaying a pop-up dialog.
