Now Coordination Server got a OSGI service from which other components can start/stop server and get configuration details. By default coordination server component will start the zk with the bundle activation (This is the previous behavior we had. i made it the default behavior for Backward compatibility ) Optionally now there is a parameter in zoo.cfg : "start_zk_server=true|false" which can be configured so that if its false coordination server component will not start the zk server. cheers, Charith > > cheers, > Charith > > >> Cheers, >> Anjana. >> >> >>> >>> --Charith >>> >>> >>>> >>>> Cheers, >>>> Anjana. >>>> >>>> >>>>> >>>>> --Charith >>>>> >>>>> >>>>> >>>>> In the >>>>> >>>>>> >>>>>> Cheers, >>>>>> Anjana. >>>>>> >>>>>> >>>>>>> >>>>>>> cheers, >>>>>>> Charith >>>>>>> >>>>>>> -- >>>>>>> Charith Dhanushka Wickramarachchi >>>>>>> Senior Software Engineer >>>>>>> WSO2 Inc >>>>>>> http://wso2.com/ >>>>>>> http://wso2.org/ >>>>>>> >>>>>>> blog >>>>>>> http://charithwiki.blogspot.com/ >>>>>>> >>>>>>> twitter >>>>>>> http://twitter.com/charithwiki >>>>>>> >>>>>>> Mobile : 0776706568 >>>>>>> >>>>>>> >>>>>>> >>>>>> >>>>>> >>>>>> -- >>>>>> *Anjana Fernando* >>>>>> Associate Technical Lead >>>>>> WSO2 Inc. | http://wso2.com >>>>>> lean . enterprise . middleware >>>>>> >>>>> >>>>> >>>>> >>>>> -- >>>>> Charith Dhanushka Wickramarachchi >>>>> Senior Software Engineer >>>>> WSO2 Inc >>>>> http://wso2.com/ >>>>> http://wso2.org/ >>>>> >>>>> blog >>>>> http://charithwiki.blogspot.com/ >>>>> >>>>> twitter >>>>> http://twitter.com/charithwiki >>>>> >>>>> Mobile : 0776706568 >>>>> >>>>> >>>>> >>>> >>>> >>>> -- >>>> *Anjana Fernando* >>>> Associate Technical Lead >>>> WSO2 Inc. | http://wso2.com >>>> lean . enterprise . middleware >>>> >>> >>> >>> >>> -- >>> Charith Dhanushka Wickramarachchi >>> Senior Software Engineer >>> WSO2 Inc >>> http://wso2.com/ >>> http://wso2.org/ >>> >>> blog >>> http://charithwiki.blogspot.com/ >>> >>> twitter >>> http://twitter.com/charithwiki >>> >>> Mobile : 0776706568 >>> >>> >>> >> >> >> -- >> *Anjana Fernando* >> Associate Technical Lead >> WSO2 Inc. | http://wso2.com >> lean . enterprise . middleware >> > > > > -- > Charith Dhanushka Wickramarachchi > Senior Software Engineer > WSO2 Inc > http://wso2.com/ > http://wso2.org/ > > blog > http://charithwiki.blogspot.com/ > > twitter > http://twitter.com/charithwiki > > Mobile : 0776706568 > > > -- Charith Dhanushka Wickramarachchi Senior Software Engineer WSO2 Inc http://wso2.com/ http://wso2.org/ blog http://charithwiki.blogspot.com/ twitter http://twitter.com/charithwiki Mobile : 0776706568
