It doesn't make sense to set the class path programmatically this way. So you have two possibilities:

1. If you want to set the classpath forever, then you should edit the environment variables of your OS. How, that depends from the Windows variant you use. Generally said: set the CLASSPATH environment variable to the values you want. Please tell us what OS you use.

2. If you want to programmatically load Java classes from locations outside the classpath, then use the URLClassLoader. Like this:

ClassLoader loader = new URLClassLoader(new URL[] { yourURL });
Class clazz = loader.loadClass(yourClassName);
