The bundle needs to be prepared before being usable by iPOJO. Without this step, iPOJO ignores your bundles. I don’t know how Eclipse works, but you may be able to use the ‘install time’ manipulator: http://felix.apache.org/documentation/subprojects/apache-felix-ipojo/apache-felix-ipojo-tools/apache-felix-ipojo-online-manipulator.html Regards, Clement > > > -----Original Message----- > From: Clement Escoffier [mailto:[email protected]] > Sent: Thursday, January 23, 2014 11:52 AM > To: Apache Felix - Users Mailing List > Subject: Re: iPOJO Components instantiated but no visible output > > Hi, > > The output are interesting, it looks like your instances are not declared > correctly.
