Jade under Ubuntu

Jade is a framework for multi-agent application development.

As it is made in Java, it can be executed in several platforms and operational systems, but it do not work under Ubuntu.

To run Jade under Ubuntu it is necessary edit the /etc/hosts and ensure that loopback interface has the 127.0.0.1 address. For default, Ubuntu defines 127.0.1.1 as loopback address for the machine name mapping.

That's it!
