NetherPanel
About
NetherPanel is a tool written in Java which is used to update World of Warcraft addons and upload addon data to online webapplications.
Launching
Launching NetherPanel is easiest using WebStart?. This way, Java will automatically check for NetherPanel updates before launching it.
You can also right-click the webstart link and save the destination file to your computer somewhere (eg. on your desktop). Then, starting NetherPanel using WebStart? is as simple as clicking that shortcut you downloaded.
Launch NetherPanel through WebStart
Alternatively, you can download the Java code of NetherPanel manually. It is packaged in a JAR file (which is basically just a ZIP file with Java code in it). You can then start this packaged JAR file by double-clicking it or running it on the console with java -Xmx512m -jar NetherPanel.jar.
Note: NetherPanel needs a bit more than the standard amount of memory Java allocates to applications. That's what the -Xmx512m option is for. If you just double-click NetherPanel.jar to start NetherPanel, this option isn't applied and NetherPanel might run out of memory while listing addons. That's not because you don't have enough memory on your PC, it's because Java didn't allocate enough to NetherPanel. You can fix this by running NetherPanel from the console with the option I mentioned or by creating a script which contains that command and double-clicking that script. Another reason to just use the WebStart? method and be done with it!
