Subject: Re: [ros-users] New rosjava Client Library






    Good morning Damon,


    congratulations for your effort with the project.


    Yesterday I was trying to test the project but I couldn't run the
    example which was posted in wiki:

http://code.google.com/p/rosjava/wiki/Welcome
rosrun rosjava run org.ros.SlaveApiTestNode


    Because I received the following message:


Unable to access jarfile
/home/jabrena/ros2/workspace2/rosjava/java/dist/rosjava.jar

    I was trying researching the source of the problem and I found a Ant
    file to build the package rosjava.jar in build.xml located in the
    path:


/home/jabrena/ros2/workspace2/rosjava/java/


    because I found in built.xml that exist a property about rosjava.jar


    <property name="jar.rosjava" location="${dist}/rosjava.jar" />



    but when I built it, I didnt find the folder dist/ and the package
    rosjava.jar



    I suppose that when I know the way to have that package, the proble
    will be solved.


    Currently I was working with previous work developed by Lorentz but
    I am really interested to move to your work.


    Cheers from Madrid

Dear ROS (Java, and Android) users,

I'm happy to announce the alpha release of a new rosjava client
library written in pure Java (http://rosjava.googlecode.com/). In
partnership with Willow Garage, I've been working on this pure Java
implementation of ROS for the last few months. We announced it
publicly yesterday at Google I/O during the Cloud Robotics tech talk
(http://www.youtube.com/watch?v=FxXBUp-4800).

One exciting aspect of rosjava is Android compatibility. You can now
integrate Android devices with your ROS-enabled robots and write apps
for them. In addition, with the newly announced Open Accessory API and
Android Development Kit, you can start controlling actuators or
reading external sensors directly from Android devices.

There are demos of Android integration in the tech talk and also
sample Android code in the rosjava repository (see
/hg/android/tutorials).

This project is under active development and should be considered
alpha quality. ROS toolchain integration is not yet complete and APIs
will be changing as we continue to move forward.

Best regards,
Damon Kohler
