Wilfried,

Given that I have a website with a static IP address, could I not use that, and thereby eliminate some (or all) of the networking issuse you described? Then, it sems that the Java program only need to grab the GPS coordinates and create an IP packet to the website, which would then use the Nextel API to send to the website.

As you can see, I have not done any programming of this sort before. I'll get a log-in to the Nextel developers site and ask about using the Nextel API.

Thanks for the help. I'd be interested in hearing if you think having my own website would simplify this process.

Bob
