Java Programming

Hello everyone, I'm new to the forums here - I'm a student at Southampton University Computer Science department, and I'm having some trouble with an application I'm writing.

I have used Eclipse to write the program, which is a System Tray application which shows an icon indicating the status of the net connection (a program born of a summer on a dodgy broadband connection).

The program consists of 3 classes of my own, and depends on a portion of the (https://jdic.dev.java.net/) project, specifically jdic.jar, for the API to put an icon in the windows system tray.

With jdic.jar added to the build path in my Eclipse project, the program works perfectly, but I want to run it as a standalone application from the command line.

After fixing my own classpath, I have been able to compile the project, but every time I try and run it, I get the following error:


Exception in thread "main" java.lang.UnsatisfiedLinkError: no tray in java.libra
ry.path

The comand I'm using to run the code is:

E:\My Documents\Degree\Computer Science\Projects\NetStat\NetStat>java -classpath ./jdic.jar;./ NetStat

where NetStat is the main class of the project.

Any help anyone could give me would be greatly appreciated, as I've always found using the command line for running more complicated java projects tricky.

If anyone wants more details of my project, or needs to see my code, just ask.

Many thanks!

PS: If anyone can give me tips as to how to run java programs under windows without being left with the dos-shell window left visible, that would also be fantastic.

Cheers all,
