I would like to write a (initially) simple Java program that writes messages to a ros topic and reads messages from another topic. Is this possible?

Thank you!

You can also use the well-known Ros Bridge package (http://rosbridge.org/doku.php?id=rosbridge_protocol_v2.0)

Ok! Now i am a little confused about how to write such a java program. I found a small java example that simply imports some "ros java packages" and extends NodeMain class to make a ros node in java.

The big question is where to find these packages, in particular org.ros.node.* and org.ros.node.topic.Publisher and so on.

Are they distributed with rosjava_core?

Yes they are, you need to install do the proper install though, its more lengthy than typical for a ros package http://docs.rosjava.googlecode.com/hg/rosjava_core/html/index.html
