Subject: ECF + Karaf + Zookeeper Author: Alex Weirig Date: Tue, 06 September 2016 03:28
Hello,

I have 3 OSGi runtimes on 3 different virtual machines in different subnets. There is no broadcasting between the subnets.

I would like to be able to use ECF inside Karaf and use Zookeeper to handle the remote/distributed bundles between the OSGi runtimes.

I have installed Karaf 4.0.6 and installed ECF SDK (latest). Here is a list of the bundles.

115 | Active | 80 | 1.2.100.v20160823-2221 | ECF Discovery ZooKeeper Provider

There is a zookeeper server running in each VM together with the OSGi runtime, ports are 2222 and 2223.

I use Eclipse with bnd(tools) to write my code and I have the following
@Component(
immediate = true
, property = {
"service.exported.interfaces=com.example.ServiceConsumerAPI"
, "service.exported.configs=ecf.generic.server"
, "ecf.generic.server.id=<a href="ecftcp://myserver.mydomain:2230/service">ecftcp://myserver.mydomain:2230/service"
}
, service = ServiceConsumerAPI.class
)

I'm not sure what to use in "service.exported.configs" and "ecf.generic.server.id" to get the service from Karaf published in my zookeeper server. I used this code when my Karaf instances where running inside the same subnet and thus broadcasting was possible.

Many thanks in advance for your precious feedback.

Regards,

Alex
