A valid command must contain all required libs, that the simulator uses. I
think, that your version of PeerfactSim.KOM needs more than that one
library. In order to include all libs to run a simulation, use "lib/*"
instead. A further problem is the separation character, which is ":" on
unix systems and ";" on Windows systems. So a valid command, with enough
memory to run large simulations can look like:
java -Xms1000M -Xmx3000M -cp lib/*:bin de.tud.kom.p2psim.SimulatorRunner
config/chord.xml

This error occurs, since no parameter is provided, which specifies the
config-file for a simulation during the start of the simulator. You must
provide a config-file to omit the error.
