Göktürk, Thank you! I used #2 below and it worked well. I was able to launch the bundle, and I saw it output the traces I had been looking for.
On the first, if I remove the contents of the metadata.xml file, how can I use iPOJO to generate the bundle? If I leave in the <ipojo/> element, and I run iPOJO's "Create Bundle", I get a warning: "Neither component types, nor instances in /Users/mcook008/Workspaces/MyEclipse 8.6/iPojoTest/metadata.xml". Start and stop are not called, although the class is marked with @Component and @Instantiate and start/stop is marked with @Validate/@Invalidate.
