Arun,1. Placing the org.osgi.compendium dependency below did not work for me.2. Which dependency should I be using org.osgi.compendium or org.apache.felix.eventadmin3. org.osgi.compendium:5.0.0 and osgi.cmpn:7.0.0 are different versions of OSGi Compendium specification. Is this correct? Thanks,Radha...
