Thank you Gunter.
This thread has given me pause to consider the application of the JNLP.

In my limited view of the world I am aware of and somewhat familiar with 
two web-centric applications deployed using JNLP: a pharmacy workflow 
app, and a CMMS app. Both seem very much like your application, in that 
they store some fairly static data, are able to cache transaction data, 
user settings, similar in scale, etc., and present a Swing desktop to 
the user. I will call them web-centric because without a connection to a 
"data center" they are of limited use. This seems a perfectly natural 
candidate for JNLP deployment, and besides the three apps so far 
discussed, I assume there is a whole host of similar apps using JNLP 
deployment.

A desktop application, in my estimation, is an application capable of 
fully standalone operation. Of course it will produce or consume data 
that will need to be exported/imported. In addition, most fairly complex 
desktop apps will make considerable use of the host systems' resources: 
file systems, network connections, spawning processes, etc.

Like the web-centric app, desktop apps range in scale. From a small 
single purpose scientific calculator type app, through a Java IDE and an 
office suite, and beyond. I have perhaps a half dozen Java desktop 
applications that range in size and complexity around the Java IDE that 
I use on a routine or occasional basis. This is the scope of the desktop 
application that prompted my comment. Of course taking my limited view 
of the world into account, these are the applications that I do not see 
being deployed using JNLP.

It is not that I have some reason to believe that using JNLP for 
deployment of this type of application is unworkable, or "bad" in some 
sense. It is simply that I don't see it being done. Web-centric, desktop 
vs browser GUI, of the type described above: yes. Small scale mostly 
single purpose desktop apps: yes, most certainly, thousands of them.

If I haven't missed something, and this type of desktop app is not being 
deployed using JNLP I begin to wonder why? If I have missed some JNLP 
deployment of this type app I would love to become aware.
