[ros-users] rosjava

hi we are creating a web interface using java to communicate between the
robot and a remote pc through wifi(adhoc network). I am trying to use
rosjava but when I try to run rostest I get an error test_rosjava/tester:
does not exist or is not executable. I tried searching for
test_rosjava/tester but I was not able find it.
So i would like to know is other any other way out to use java with ros.

Regards,
shayan
