Tutorial Level: INTERMEDIATE
Next Tutorial: Service Discovery via Polling
Code
Publishing is very straightforward. The following explicitly details each element required to publish a ros master.
1 // imports
2 import com.github.ros_java.zeroconf_jmdns_suite.jmdns.Zeroconf;
3 import com.github.ros_java.zeroconf_jmdns_suite.jmdns.StandardLogger;
4
5 // and in your code
6 Zeroconf publisher = new Zeroconf(new StandardLogger());
7 publisher.addService("DudeMaster", "_ros-master._tcp", "local", 8888, "Dude's test master");
For ros master services in particular, we could pull ros information directly from rosjava to fill out some of the above details - if you have an interest in getting this implemented contact <d DOT stonier AT gmail DOT com>.
Example
Example code can be found in the jmdns tutorials.
