This is expected. > Shouldn't each > bundle load and initialize its own copy of imported class? No. I think the kind of behavior you want can be found in service factories. When you register a service using a service factory, each requesting bundle gets it's own copy of the service object. So you could use a non-static property in a service set up as a service factory. Since only one copy of the class is loaded, any static variable will be shared among all service instances. thanks david jencks > > Thanks, > Ludvik > > -- > View this message in context: > http://karaf.922171.n3.nabble.com/Static-variables-tp3287037p3289607.html > Sent from the Karaf - User mailing list archive at Nabble.com.
