Synopsis

javaws [ run-options ] jnlp

javaws [ control-options ]

run-options: Command-line run-options. The run-options can be in any order. See Run-Options.

control-options: Command-line control-options. The control-options can be in any order. See Control-Options.

Description

Note: The javaws command is not available on Oracle Solaris.

The javaws command starts Java Web Start, which is the reference implementation of the JNLP. Java Web Start starts Java applications and applets hosted on a network.

If a JNLP file is specified, then the javaws command starts the Java application or applet specified in the JNLP file.

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.

Run-Options

-offline: Runs Java Web Start in offline mode.
-Xnosplash: Does not display the initial splash screen.
-open arguments: When specified, this option replaces the arguments in the JNLP file with -open arguments.
-print arguments: When specified, this option replaces the arguments in the JNLP file with -print arguments.
-online: Uses online mode. This is the default behavior.
-wait: The javaws process does not exit until the application exits. This option does not function as described on Windows platforms.
-verbose: Displays additional output.
-Joption: Passes option to the Java Virtual Machine, where option is one of the options described on the reference page for the Java application launcher. For example, -J-Xms48m sets the startup memory to 48 MB. See java(1).
-system: Runs the application from the system cache only.

Control-Options

-viewer: Shows the cache viewer in the Java Control Panel.
-clearcache: Removes all non-installed applications from the cache.
-userConfig property-name: Clears the specified deployment property.
-userConfig property-name property-value: Sets the specified deployment property to the specified value.
-uninstall: Removes all applications from the cache.
-uninstall jnlp: Removes the application from the cache.
-print import-options jnlp: Imports the application to the cache.

Import-Options

-silent: Imports silently (with no user interface).
-system: Imports application to the system cache.
-codebase url: Retrieves resources from the specified codebase.
-shortcut: Installs shortcuts if the user allows a prompt. This option has no effect unless the -silent option is also used.
-association: Installs associations if the user allows a prompt. This option has no effect unless the -silent option is also used.

Note: The command javaws -shortcut -uninstall removes both association as well as the implementation.
