Hi,

I'm writing a ‘native’ OpenDaylight application which uses the OSGi interfaces (Java APIs) exposed by OpenDaylight framework (Helium SR3). In my particular case I just want to get all the hosts (of a Mininet network) over the IfIptoHost interface of the HostTracker module (i.e. org.opendaylight.controller.hosttracker.IfIptoHost). I am following the post "http://thenewstack.io/writing-opendaylight-applications/" and what I basically do is:

  1. Register to the IfIptoHost service by creating a dependency in my app's bundle activator within the configureInstance() method: c.add(createContainerServiceDependency(containerName).setService(IfIptoHost.class).setCallbacks(...).setRequired(true))

  2. Once I got the IfIptoHost osgi service I try to make the following call:

    Set<HostNodeConnector> allhosts = iptoHost.getAllHosts();

I am debugging my code under Eclipse (ODL remote debugging) and I can see that allhosts set is empty. However, if I run the HTTP/REST call shown below I get all the hosts within the response. DLUX is also showing the hosts.

http://localhost:8080/restconf/operational/network-topology:network-topology/topology/flow:1/

What could be the problem? Is there any alternative to get all the hosts of my mininet's network using the ODL's JAVA API?

BR,

Juan
