Compiling the application

To compile our application we need to include the following JARs on our classpath:

• jtrix.jar because we use basic Jtrix constructs such as IService and IRemote.
• facets1.jar because we use ``standard'' facets and related classes, including IConsoleFacet and Property.
• libjtrix.jar because we use Debug, ConsoleFacetFactory and others.
• beatrix.jar for Beatrix itself.

Were we to write a more complex application we might of course need more JARs.

We compile the whole into a single JAR file which we name skeleton2.jar. We can optionally include a manifest with a line like this:

jar-label: skeleton2

This labels the JAR for SAS, giving it a handy way of referencing it in future. If we omit this then it will take the JAR's filename as a label instead. However, giving a JAR label explictly is a good way of ensuring it gets a helpful name we know about. JARs with the same label are considered to be the same JAR, although a JAR hash code is used to double-check, and helps prevent Jtrix fetching JARs it already has. See also Section .
