Hi Mr. Herzog,

Here is info about doing this taken from Maxim's iButton website:

Installing OneWireViewer
If clicking on the OneWireViewer JNLP file fails to start the application, right-click on the URL and save the file to your desktop. Then double-click on the file to launch Java Web Start. Now you can delete the *.jnlp file from your desktop. You can then launch the OneWireViewer, first by loading Java Web Start and then by selecting the OneWireViewer.
You can run the OneWireViewer from the command-line (without Java Web Start) like a standard Java application, but the jar files must be downloaded manually. First, install the drivers appropriate for your platform. Then, get OneWireViewer.jar and OneWireAPI.jar and use the following command line:

java -cp "OneWireViewer.jar;OneWireAPI.jar" OneWireViewer

From this info, depending on how your path variable is setup, you should be able to run it from any directory.  If your path variable doesn't include where your java execution program is then you would need to write a simple batch file to run the file in the other directory if you don't want the onewireviewer java file in your java execution program directory.

Let me know if this helps or not.
