How can I change classpath at runtime?

System.setProperty("java.class.path","%x%"); is executed,
System.getProperty("java.class.path");
shows new classpath, but
Class.forName("some.class.that.is.in.%x%");
throws an exception.
I know this is a bug in JDK .. but is there any alternative to change classpath at runtime ?

I don't think you can change the CLASSPATH at runtime.
An alternative, if you know what classes you're going to use ahead of time, is to use a class derived from ClassLoader. This will let you load and use classes without relying on the CLASSPATH.
