@MarkoTopolnik what i meant was, dont we need to escape `.` like '\\.' to be treated as a dot character?? – PermGenError Nov 20 '12 at 10:48

@GanGnaMStYleOverFlowErroR Since this is not a regex string, no, we don't – Marko Topolnik Nov 20 '12 at 10:49

Class.forName() takes a class name such as java.lang.Thread as parameter, not a file path. You have to load your class by using a dynamic ClassLoader

You have an error in your Class.forName().
You have to supply the fully qualified class name (FQCN) to this method.
If you want to load a certain class from an external source you have to write your own ClassLoader.
