Another option is alive and kicking Open JNLP lead by Kevin Herrboldt at works on all platforms including Mac OS 9 and other JDK 1.1 platforms.Q: Does Web Start support downloading jars using FTP?Web Start cannot handle FTP connections because it depends on HTTP headers for determining things like last-modified date. The JNLP spec explicitly limits JNLP to the HTTP protocol. The following is a short excerpt from the book "A Programmer's Guide to Jini Technology" by Jan Newmarch.The full chapter is available online at the face of it, Jini and JNLP appear to occupy similar spaces in that they both allow code to be migrated to a client machine and to execute there.A simple workaround is to create a servlet that takes in your arguments as parameters in the URL (e.g.attribute in the JNLP file that your servlet sends back to Web Start. no installer, no applets) using one of the two open-source client as a start takes probably just a couple of days and should be sufficient for in house usage.Sun released Java 1.4 in mid-February 2002 as scheduled for Linux, Windows and Solaris. Web Start has an update detection mechanism that can inform the user when a new release is available. However, Web Start itself (without a JRE) is expected to be a download of 400k or less.

If a service changes to use another service, it does not need to inform anyone else about this change.

The converse question is: if JNLP is used to find an application, what is the value of Jini in this?

The answer to this lises in the distributed management of Jini services.

If one of the packages changes, then the JNLP file has to be updated.

It gets more complex if one of the packages changes to become dependant upon another new package: that new package has to be added to the JNLP file.
