The javaws command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP). Java Web Start launches java application/applets hosted on a network. Without any options javaws will launch the Java JNLP Application Manager, from which users can launch applications/applet or configure Java Web Start. If a URL for a JNLP file is specified, javaws will launch the Java application/applet specified in the JNLP file. OPTIONS
The javaws launcher has a set of options that are supported in the current release. However, the options may be removed in a future release. All -X options are non-standard and subject to change. -offline Runs Java Web Start in offline mode. -uninstall URL Removes a specific application/applet from the user's cache, as indicated by the URL for the JNLP file.

The process exit code will be either 0 if successful or 1 if not. -codebase URL Replaces the codebase with URL in the jnlp file specified when importing the resources. URL must be a valid URL. -system Uses the system cache instead of the user cache. -shortcut Allows the creation of shortcuts during silent import. -association Allows the creation of associations during silent import. -open arguments If specified, replaces the arguments in the jnlp file with -open arguments. -print arguments If specified, replaces the arguments in the jnlp file with -print arguments. -online Runs in online mode (default behavior). -viewer Runs the Java Application Cache Viewer (default if no URL is specified). -userConfig property-name Clears the specified deployment property. -userConfig property-name property-value Sets the specified deployment property to the specified value. -wait If specified, the javaws process will not exit until the application exits.
