It is also not entirely necessary to make an .exe. On Windows, at least, .jar files are executable so long as there is a Java runtime installed and the .jar extension has been set up on the machine.
[NOTE: I just discovered that something that has broken the file association, which had previously worked for me. It now only works when I am administrator, and the JAR icon even disappears otherwise. I assume that some recent install has messed with that and the candidates are (1) OpenOffice.org 3.0, (2) WinRAR, or (3) a Java update download. However, the following all work when the association is made to work.]
The "program" Clicker.jar runs as a Java application when (1) I double-click on it in a Windows Explorer window, (2) When I create a console shell where I am in the same directory and I perform the command ">Clicker.jar" (3) when I send a shortcut to my desktop and double-click on it, and (4) when I put the full path in the Windows XP Run ... box.
I don't know that these will be found in a PATH search, and I normally wouldn't arrange that anyhow.
