[Advanced-java] How to String->Class (not instance of Class c lass)?

[Pollard@xxxxxxxxx (Pollard, Jim)]

i'm not sure what you were doing with c.class (the Class object has no
public properties), but i think what you are missing is a call to
newInstance() something like this :

String className = getClassName(); //get class name from config file. for
example "SpecialRequestIDHome"
Class c = Class.forName(className);
Object d = c.newInstance();
Object ridHome = PortableRemoteObject.narrow(ref, d.class);
