Codebase and class loading

The netlet's descriptor defines the Jar files available to the netlet. Therefore, it determines which classes a netlet can use.

When a netlet is initialised all its Jars labelled as non-lazy in the descriptor must have been downloaded already. Remote Jar files are retrieved via HTTP or HTTPS.

If a netlet refers to a class outside its codebase, a java.lang.ClassNotFoundException is thrown.
