.TH javaws 1 "9 Sep 2010"
.SH NAME
javaws - a Java Web Start client
.SH SYNOPSIS
.B javaws
[-run-options] jnlp-file
.br
.B javaws
[-control-option]
.SH DESCRIPTION
.B 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
.B javaws
is from the IcedTea project and is based on the NetX project.
.PP
A JNLP file is an xml file that describes how to securely run a
remote Java application or a Java applet.

.SH OPTIONS
When specifying options, the name of the jnlp file must be the last
argument to
.B javaws
- all the options must preceede it.
.PP
The jnlp-file can either be a url or a local path.
.PP
.B Control Options
.PP
By default
.B javaws
will launch the jnlp file specified on the command line. The control
options can be used to change this behaviour.
.TP 12
\-about
Shows about dialog.
.TP
\-viewer
Shows the trusted certificate viewer. This allows a user to list, examine, remove
or export trusted certificates. Note that this only reflects the certificates
trusted by
.B javaws
and not any other certificates or programs.

.PP
.B Run Options
.PP
In the default mode, the following run-options can be used:
.TP 12
\-version
Prints out version and exit
.TP
\-arg arg
Adds an application argument before launching.
.TP
\-param name=value
Adds an applet parameter before launching.
.TP
\-property name=value
Sets a system property before launching.
.TP
\-update seconds
Update check if seconds since last checked.
.TP
\-license
Display the GPL license and exit.
.TP
\-verbose
Enable verbose output. Very useful in debugging.
.TP
\-nosecurity
Disables the secure runtime environment.
.TP
\-noupdate
Disables checking for updates.
.TP
\-headless
Disables download window, other UIs.
.TP
\-strict
Enables strict checking of JNLP file format. Any deviations from
the JNLP DTD will cause
.B javaws
to abort.
.TP
\-xml
The jnlp files will be checked more strictly for XML validity
.TP
\-allowredirect
Allow to follow 301, 302, 303, 307 and 308 redirections for javaws
applications
.TP
\-Xnofork
Do not create another JVM, even if the JNLP file asks for running in
a separate JVM. This is useful for debugging.
.TP
\-Xclearcache
Clean the JNLP application cache.
.TP
\-Xignoreheaders
Skip jar header verification.
.TP
\-Jjava-option
This passes along java-option to the java binary that is running
javaws. For example, to make javaws run with a max heap size
of 80m, use -J-Xmx80m.
.TP
\-help
Print a help message and exit.

.SH BUGS
There arent any known bugs. If you come across one, please file it at
    http://icedtea.classpath.org/bugzilla/
.br
Please run javaws 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
(ot the jnlp/html file or application itself)  when filing out the bug report.
