Run the application

Web Start

World (Web Start)

You'll need to add http://jminor.no-ip.org to the Java exception site list.

Getdown

empdept-getdown.zip

Zip file containing the necessary files for running with Getdown.

Local JAR file

world.zip

Zip file containing a jar file along with an assortment of launch files for running the application without WebStart. Note that the remote configurations all assume the server is running on localhost.
