Subject Re: OSGi
Date Fri, 20 Jan 2017 10:42:38 GMT
Hello all,

I have also added a package in org.apache.river bundle to create the river
service in osgi environment ( Here RIver
uses NonActivatableServiceDescriptor).

package name is  org.apache.river.start.ext


As river bundle is system fragment, i have to remove the groovy dependency.
So i removed groovy files.

net.jini.config.Component.groovy

net.jini.config.GroovyConfig.groovy



Thanks & Regards,

Bharath
