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 Network 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 argument, 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 argument 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

AUTHOR

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.
