By "at runtime" do you mean after the application has already started, i.e., 
too late to change the classpath that you load the application with?  If so, 
then yes, AFAIK you will need to use your own classloader.  You don't 
actually need to write the classloader yourself, you can just use an 
URLClassLoader.
