Compiling the application

For compilation to work we need these JARs on our classpath:

1. jtrix.jar which defines INetlet etc.
2. facets1.jar which contains IBootstrapFacet and IInputStream.
3. libjtrix.jar because we use its utility classes FacetInputStreamWrapper and NullService. Recall we also used the NullService in Hello1Client, and for the same job.

We'll put our Hello3Client into hello3.jar along with IHelloFacet. As usual we don't need a manifest in this JAR.
