Ubuntu Manpage: javaws - a Java Web Start client

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.
