There are not any out-of-the-box software packages that I am aware of which are ready for OpenJAUS. There is the OCU project started by Jim which can be found here:
code.google.com/p/openjaus-ocu/ I am not sure the state of that project, but I think that would be the closest thing to what you seek currently. OpenJAUS has been integrated and tested with a number of proprietary JAUS OCUs such as OpenUMI, Mobius and MOCU, but I don't know the current status of any of those systems and OpenJAUS integration.
There is ojVehicleSim in the distribution which will show a fully functional JAUS vehicle simulator, the only issue is visualization of that data.
