Using internal services of the SDN controller like the TopologyService

[HansChristian]

Hi, I'm new here so hopefully this is the right place to ask my question.

Currently, I try to implement an internal SDN application for the HP VAN SDN controller. The controller is running in a seperate VM, which is the same for mininet. I also have installed the SDK and I'm able to compile a simple SDN application generated by the gen-sdn-app script via mvn clean install. 

Now, I'd like to play around with the controller's capabilities. First, I like to read the topology using the controller's topology service - see http://h22208.www2.hpe.com/eginfolib/networking/docs/sdn/sdnc2_6/hp-sdn-apidoc-2.6.8/com/hp/sdn/topo...

 How can I get an object of that service?

 TopologyService ts = new TopologyService() does not work.

 Thanks in advance!

protected volatile TopologyService ts;

works fine
