Could you tell me what happens when you remove the <ipojo/> element too leaving the metadata.xml empty? If above trick didn't work and you want to stick with eclipse-ipojo-plugin while using annotations. 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. Also it seems to me that your development environment is heavy. Instead of embedding Felix into eclipse you can use its own Equinox launcher. I suggest you to have a look at http://felix.apache.org/site/apache-felix-ipojo-eclipse-integration.html where you can see basic setup.(You can use annotations or metadata of your choice in this setup) Gokturk > > Mike > > > > On 10/11/12 8:54 PM, "Göktürk Gezer" <[email protected]> wrote: > > >Well i thought at first that you didn't specify metadata.xml but i see now > >that you did.
