Table

shows some of the JARs provided by Jtrix.org. There are a couple of things of particular interest.

First, jtrix.jar is guaranteed to be available on any node on which a netlet runs. That means when a netlet's descriptor lists what JARs it needs it can omit mentioning jtrix.jar--it will already be there for it.

Second, JARs such as hospitality_facet.jar and nodality_facet.jar often crop up, and they contain the just the facets that a service offers. They are very useful to compile and run against because they are small and leave the actual implementation to the services themselves.
