NAME

javaws – a Java Web Start client

SYNOPSIS

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

DESCRIPTION

javaws is an implementation of a JNLP client. It uses a JNLP (Java Net‐
work Launch Protocol) 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.

OPTIONS

When specifying options, the name of the jnlp file can be after the
command, the -jnlp option, an option with no arguments, or after an
argument with an option that takes one argument. A html file that
launches a jnlp can be specified after the -html option.
The jnlp-file can either be a url or a local path.
The JNLP file should only be specified once, whether as a main argu‐
ment, after -jnlp or through an html file.

Control options:

-about Shows a sample application.(No argument expected)

-help Prints out information about supported command and basic
usage.(No argument expected)

-license Display the GPL license and exit.(No argument expected)

-viewer Shows the trusted certificate viewer.(No argument expected)

-Xclearcache
Clean the JNLP application cache.(No argument expected)

Run options:

-allowredirect
Follows HTTP redirects.(No argument expected)

-arg arg Adds an application argument before launching.(Expected one
or more arguments)

-headless Disables download window, other UIs.(No argument expected)

-html Location of HTML file to launch (url or file). You can use
parameter ALL or numbers (like 1 2 5) to select applets on
page. However experimental, this switch should keep you
still in safety.(Expected one or more arguments)

-jnlp Location of JNLP file to launch (url or file).(Exactly one
argument expected)

-nosecurity Disables the secure runtime environment.(No argument
expected)

-noupdate Disables checking for updates.(No argument expected)

-param name=value
Adds an applet parameter before launching.(Expected one or
more arguments)

-property name=value
Sets a system property before launching.(Expected one or
more arguments)

-strict Enables strict checking of JNLP file format.(No argument
expected)

-update seconds
Check for updates.(Exactly one argument expected)

-verbose Enable verbose output.(No argument expected)

-version Print the IcedTea-Web version and exit.(No argument
expected)

-Xignoreheaders
Skip jar header verification.(No argument expected)

-xml Uses a strict XML parser to parse the JNLP file.(No argu‐
ment expected)

-Xnofork Do not create another JVM.(No argument expected)

-Xoffline Prevent ITW network connection. Only cache will be used.
Application can still connect.(No argument expected)

-Xtrustnone Instead of asking user, will foretold all answers as no.(No
argument expected)

EXAMPLES
javaws -about
Shows basic help and about informations.

javaws -about -headless
Shows basic help and about informations in terminal only.

javaws -Xnofork -Xignoreheaders -allowredirect -Xoffline
http://mypage.web/dangerous.jnlp
Will start dangerous.jnlp application, originally from
mypage.web, without downloading it, without headers check
and in forced single VM.

BUGS

There aren’t any known bugs. If you come across one, please file it at:
http://icedtea.classpath.org/wiki/IcedTea-Web#Filing_bugs
http://icedtea.classpath.org/bugzilla

Please run in debug (-verbose switch or itw-settings setting or
ICEDTEAPLUGIN_DEBUG variable set to true) mode and include that output
(best is from java console) with URL to jnlp or html file (or the
jnlp/html file or application itself) when filing out the bug report.
