javaws - a Java Web Start client
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.
By default javaws will launch the jnlp file specified on the command line. The control options can be used to change this behaviour.
Shows a sample application that can be used to test the basic functionality of this implementation.
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.
In the default
mode, the following run-options can be used:
Directory where the cache and certificates to be used are stored.
Adds an application argument before launching.
Adds an applet parameter before launching.
Sets a system property before launching.
Update check if seconds since last checked.
Display the GPL license and exit.
Enable verbose output. Very useful in debugging.
Disables the secure runtime environment.
Disables checking for updates.
Disables download window, other UIs.
Enables strict checking of JNLP file format. Any deviations from the JNLP DTD will cause javaws to abort.
Sets the umask for files created by an application.
Do not create another JVM, even if the JNLP file asks for running in a separate JVM. This is useful for debugging.
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.
Print a help message and exit.

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