Hi,

since rosjava is still experimental, the Java files generated for 
messages and services of the common stacks are not contained in the 
binary .deb packages. This creates problems when rosjava packages depend 
(directly or indirectly) on these messages or services.

In order to use rosjava packages together with a ROS binary 
installation, we built a .jar file that contains all required .class 
files for the cturtle release. To use it, you just need to download it 
[1] and add it to your ROSJAVA_AUX_CLASSPATH environment variable. It 
will be added at the end of the classpath that rosjava uses for 
compilation, so if you have overlaid source packages for some of the 
messages, they will be used instead. See also [2]

We chose this solution since it does not require any changes to the 
packages and works with multiple binary/source installations. You can 
create your custom .jar file by just adapting the dependencies in the 
rosjava_deps package [1], compiling it and calling `make jar`.  Thanks 
to Lorenz for help with the implementation!

best,
Moritz
