       javaws - a Java Web Start client

       javaws [-run-options] jnlp-file
       javaws [-control-option]

       javaws  is an implementation of a JNLP  client. It uses a JNLP (Java Network Launch Proto-
       col) file to securely run a remote Java application or a Java applet.  This implementation
       of javaws is from the IcedTea project and is based on the NetX project.

       A JNLP file is an xml file that describes how to securely run a remote Java application or
       a Java applet.

       When specifying options, the name of the jnlp file must be the last argument to	javaws	-
       all the options must preceede it.

       The jnlp-file can either be a url or a local path.

       Control Options

       By  default  javaws  will  launch the jnlp file specified on the command line. The control
       options can be used to change this behaviour.

       -about	   Shows a sample application that can be used to test the basic functionality of
		   this implementation.

       -viewer	   Shows  the  trusted	certificate  viewer. This allows a user to list, examine,
		   remove or export trusted certificates. Note that this only reflects	the  cer-
		   tificates trusted by javaws and not any other certificates or programs.

       Run Options

       In the default mode, the following run-options can be used:

       -basedir dir
		   Directory where the cache and certificates to be used are stored.

       -arg arg    Adds an application argument before launching.

       -param name=value
		   Adds an applet parameter before launching.

       -property name=value
		   Sets a system property before launching.

       -update seconds
		   Update check if seconds since last checked.

       -license    Display the GPL license and exit.

       -verbose    Enable verbose output. Very useful in debugging.

       -nosecurity Disables the secure runtime environment.

       -noupdate   Disables checking for updates.

       -headless   Disables download window, other UIs.

       -strict	   Enables  strict checking of JNLP file format. Any deviations from the JNLP DTD
		   will cause javaws to abort.

		   Sets the umask for files created by an application.

       -Xnofork    Do not create another JVM, even if the JNLP file asks for running in  a  sepa-
		   rate JVM. This is useful for debugging.

		   This  passes  along java-option to the java binary that is running javaws. For
		   example, to make javaws run with a max heap size of 80m, use -J-Xmx80m.

       -help	   Print a help message and exit.

       ~/.icedtea/deployment.properties specifies the settings used by javaws

       There arent any known bugs. If you come across one, please file it at
       Please run javaws in verbose mode and include that output along with the  jnlp  file  when
       filing out the bug report.
