public class Test() {

public static void main(String[] args) {

CustomClassLoader ccl = new CustomClassLoader();
Thread.currentThread().setContextClassLoader(ccl);
Foo foo = new Foo();
}
}

In the above.. why is the class Foo not loaded by the custom class loader?
What do I need to do to make Foo load using the ccl classloader.

I know I can do this..

ccl.loadClass("Foo").newInstance() instead of new Foo(). But Foo also instantiates class SubFoo in return using the new operator and that point I would have to replace the new SubFoo() call with ccl.loadClass("SubFoo").newInstance().

I don't want to replace all "new" calls with ccl.loadClass(...) .
Especially since Foo/SubFoo could be in a third party jar.

The context classloader is actually not as magical as one would hope. It's there, and you're supposed to use it if you're writing tools and containers and the like -- but it's not as though the JVM actually uses it for anything; only libraries do.

There's a flaw in your chain of inferences here, and that's good news for you: the classes loaded as a result of loading Foo will be loaded by the ClassLoader that loaded Foo, automatically. So you only have to load one class to create a new "world".
