The wizard code is simply to build a module, however since the facet we are adding has a runtime available you suddenly get the runtimes available in the wizard. Also remember the install delegate we had at the begining, well we have use that to determine whether a runtime was assigned and reference it if it was.

As you can imagine this means that information from your runtime can be used to set up special stuff in the project, such as adding the runtime's project classpath to the project. OK... lets see all that in action.
