> h2. Analysis
> After a look in the Artemis source code we come to the following conclusion:
> * {{org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory}}
> ** implements
> *** {{org.apache.activemq.artemis.spi.core.remoting.ConnectorFactory}}
> ** and not
> *** {{org.apache.activemq.artemis.core.server.ConnectorServiceFactory}}
> ** ConnectorService which is created by the ConnectorServiceFactory is deprecated!
> *** is there an alternative way to add a connector via REST Jolokia API?
>
> h2. Example (how it should work (,as I understand))
> from Web Console:
> {{createConnectorService(java.lang.String, java.lang.String, java.util.Map)}}
> # test-connector
> # org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnectorFactory
> # {"host": "127.0.0.1", "port": 61616}
