    Knowledge about Basic Java programming,cloud computing,some programming IDEs like Eclipse is sufficient to work on cloudsim. Sorry, I've not worked on cloudsim.

    This would answer all your questions- http://code.google.com/p/cloudsim/wiki/FAQ

    If you have any doubt regarding the implementation, feel free to ask here.

    Looks like there is a mismatch between ur jdk and jre. Which version of jdk u r using?
    I have seen people with java7 facing this problem.
    Try reinstalling jdk and jre so that both have same version.
    :)
    Hope it helps!
