Hi, >>Could you tell me what happens when you remove the <ipojo/> element too >>leaving the metadata.xml empty?
I get an error when there is no contents in the metadata.xml file. >>I could suggest you a trick to define a bogus >>component inside metadata.xml(Will require you to maintain a bogus class) >>so that eclipse-ipojo-plugin will not fail on metadata.xml and move along >>its way with annotations. I added a bogus class into the cook.michael package and put the @Component/@Instantiate/@Validate/@Invalidate back into the code. Then added this component to the metadata.xml file: <ipojo> <component className="cook.michael.BogusClass"/> </ipojo> The above results in the start and stop not being invoked. >>Instead of embedding Felix into eclipse you can use its own Equinox >>launcher. I'm developing atop Felix, because the target device is Felix based, so I would like to keep it on the same platform. Thank you for your help.
