       javaws - a Java Web Start client

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

       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.

       When  specifying	 options,  the	name of the jnlp file must be the last
       argument to javaws - all the options must preceede it.

       The jnlp-file can either be a url or a local path.

       Control Options

       By default javaws will launch the jnlp file specified  on  the  command
       line. The control options can be used to change this behaviour.

       -about	   Shows about dialog.

       -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 javaws
		   and not any other certificates or programs.

       Run Options

       In the default mode, the following run-options can be used:

       -version	   Prints out version and exit

       -arg arg	   Adds an application argument before launching.

       -param name=value
		   Adds an applet parameter before launching.

       -property name=value
		   Sets a system property before launching.

       -update seconds
		   Update check if seconds since last checked.

       -license	   Display the GPL license and exit.

       -verbose	   Enable verbose output. Very useful in debugging.

       -nosecurity Disables the secure runtime environment.

       -noupdate   Disables checking for updates.

       -headless   Disables download window, other UIs.

       -strict	   Enables strict checking of JNLP file format. Any deviations
		   from the JNLP DTD will cause javaws to abort.

       -xml	   The jnlp files will be checked more strictly for XML valid‐

		   Allow to follow 301, 302, 303, 307 and 308 redirections for
		   javaws applications

       -Xnofork	   Do  not  create another JVM, even if the JNLP file asks for
		   running in a separate JVM. This is useful for debugging.

		   Clean the JNLP application cache.

		   Skip jar header verification.

		   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.

       -help	   Print a help message and exit.

       $XDG_CONFIG_DIR/icedtea-web/  specifies  the  set‐
       tings used by javaws

       $XDG_CONFIG_DIR/icedtea-web/log	(may  be  set to different location by
       you) contains file log files (if	 enabled).   itw-cplugin-date_time.log
       for  native  part  of  plugin, itw-javantx-date_time.log for everything

       $XDG_CONFIG_DIR/icedtea-web/security/java.policy contains granted  per‐
       missions for selected unsigned apps

       $XDG_CONFIG_DIR/icedtea-web/security/trusted.*certs   contains  various
       stored certificates

       $XDG_CACHE_DIR/icedtea-web/cache contains cached runtime	 entries  (amy
       be changed by you)

       $XDG_CACHE_DIR/icedtea-web/pcache contains saved application data

       $XDG_CACHE_DIR/icedtea-web/tmp contains temporary runtime files

       $XDG_RUNTIME_DIR/icedteaplugin-user-*/  contains	 in  and  out pipe for
       native<->java communication and (if enabled) debugging pipe

       Where $XDG_CONFIG_DIR, $XDG_CACHE_DIR and $XDG_RUNTIME_DIR are  set  as
       ~/.config, ~/.cache and /tmp or /var/tmp if not set.

       There arent any known bugs. If you come across one, please file it at
       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.
