Revision history [back]

Hi Lorentz, I read your answer and I tryed to update an example.

In manifest file, I added the following line after the line about std_msgs

<depend package="std_msgs" />
<depend package="sensor_msgs" />

Later, I executed rosmake because I thought that rosjava could generate package for sensor_msgs but when I tried to update a Publisher object, I didn't use any object from the package about sensor_msgs.

            Publisher<org.ros.message.std_msgs.String> publisher =
                node.newPublisher("battery", "std_msgs/String");

How to use sensor_msgs with lateset ROSjava? what is the difference between std_msgs and sensor_msgs?
