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)

-Xcacheids

List available IDs in cache, which you can use to delete individual applications.(Expected none or one argument)

-Xclearcache

Clean the JNLP application cache. If you pass argument, only specified application is deleted.(Expected none or one argument)

Run options:

-allowredirect

Follows HTTP redirects.(No argument expected)

-arg arg

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

-browser

Launch embeded browser. Use in great need only!(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. You need also deployment.security.itw.ignorecertissues to workaround corrupted signatures(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)

-startuptracker

Enable startup time tracker(No argument expected)

-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¶

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.
