Cannot subscribe to topics using rosbag play
I would like to subscribe to a message which is being played back from a bag file. Whenever I launch my node that listens to the topic, I get the following error:
Dec 11, 2012 6:27:57 AM org.ros.internal.transport.ConnectionTrackingHandler exceptionCaught SEVERE: Channel exception: java.net.ConnectException: connection timed out
The rxgraph output shows my node, but it is in red. It shows the bagplay node and rosout normally. Can ROSJava not connect to the topics published from a bag file? What am I doing wrong here?
