I have the class name stored in a property file. I know that the classes store will implement IDynamicLoad. How do I instantiate the class dynamically?

Right now I have

     Properties foo = new Properties();
    foo.load(new FileInputStream(new File("ClassName.properties")));
    String class_name = foo.getProperty("class","DefaultClass");
    //IDynamicLoad newClass = Class.forName(class_name).newInstance();

Does the newInstance only load compiled .class files? How do I load a Java Class that is not compiled?
