javaws(1) General Commands Manual javaws(1) NAME
javaws - a Java Web Start client SYNOPSYS
javaws [-run-options] jnlp-file javaws [-control-option] 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 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 a sample application that can be used to test the basic functionality of this implementation. -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: -basedir dir Directory where the cache and certificates to be used are stored. -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. -umask=value Sets the umask for files created by an application. -Xnofork Do not create another JVM, even if the JNLP file asks for running in a separate JVM. This is useful for debugging. -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. -help Print a help message and exit. FILES

There arent any known bugs. If you come across one, please file it at http://icedtea.classpath.org/bugzilla/ Please run javaws in verbose mode and include that output along with the jnlp file when filing out the bug report. AUTHOR
