    I believe you are missing the init() method

    This might help a little

    load: class Project1.class" not found.
    java.lang.ClassNotFoundException: Project1.class"

    Its strange that there is a quote char at the end of the class name?

    Remove the "s around the "code=Project1.class" to be code=Project1.class
    and see what happens
