NAME

SYNOPSIS

PARAMETERS

options

Command-line options. Options may be in any order. For a discussion of the various options, see OPTIONS below.

URL

Uniform Resource Locator (URL) of the JNLP (Java Net-work Launching Protocol) file.

DESCRIPTION

The javaws command launches Java Web Start, which is the reference implementation of the Java Network Launching Protocol (JNLP). Java Web Start launches Java applications/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.

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.
