Some classes and resouces related to the former "Create sample RESTful Service" wizard were moved from org.jboss.tools.ws.ui to org.jboss.tools.ws.jaxrs.ui as part of JBIDE-9223, then replaced with other classes and resources as part of JBIDE-17151, but some classes still required by the "Simple Web Service" wizard were lost in the process, as reported in JBIDE-17459. The most straightforward solution for JBT 4.2.0.Beta2 was to restore those files and simply comment out the extension for the "Create sample RESTful Service" in org.jboss.tools.ws.ui/plugin.xml

But now it is time to do some cleanup.
