Compiling the application

To compile our three classes (Hello2Client, Hello2Provider and IHelloFacet) we need these JARs on our classpath:

1. jtrix.jar as always, as it contains INetlet, IService and everything else that defines Jtrix.
2. nodality_facet.jar which contains the extras that we imported to Hello2Provider.

Then we'll bundle all our compiled .class files into a single JAR called hello2.jar, and again we don't even need a manifest.
