javaws (1)
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 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:
icedtea.classpath.org/wiki/IcedTea-Web#Filing_bugs
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.
