The very commonly asked .. but unanswered requirement for a password change script
Noob question ..

My Java based application needs to change some user passwords based on some user actions. Since this application can run on Redhat AS2.1 / AS4.0 / Solaris 9 etc, the most safe and portable solution that I could think of was: Use expect.

Now, expect is not available on all platforms, and I don't want to install tcl / tk / expect to be able to run my application. So, what's the simplest way for me to achieve what I want to?

Keep a expect binary and required libraries in a local directory in the application? How can I do this? Any other ideas

javaws-itweb

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

       ~/.icedtea/deployment.properties specifies the settings used by javaws

BUGS

       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.
