You might need to open a case with support to help but I would suggest the following
1) set the controller loglevel = 3 and logsize to 5000 in the robot.cfg
2) set the tomcat probe loglevel to 5 and logsize to 15000
3) restart and check the controller log and the _tomcat.log for more details
In the controller.log at loglevel 3 you should see the full command line trying to be executed.
try opening a command prompt and running the command manually this some times will give you some additional information.
The last two things to try would be to deploy the java_jre from the archive to the robots
last would be to add a variable to the environment tab on the controller as
Name: PATH
Value: <Blank Space>
If there is something in the environment on the system path setting the above variable and restarting the robot would eliminate this problem.
hope this helps.
