Is it possible to load a class in Java and 'fake' the package name/canonical name of a class? I tried doing this, the obvious way, but I get a "class name doesn't match" message in a ClassDefNotFoundException.

The reason I'm doing this is I'm trying to load an API that was written in the default package so that I can use it directly without using reflection. The code will compile against the class in a folder structure representing the package and a package name import. ie:

./com/DefaultPackageClass.class

// ...
import com.DefaultPackageClass;
import java.util.Vector;
// ...

My current code is as follows:

public Class loadClass(String name) throws ClassNotFoundException {
    if(!CLASS_NAME.equals(name))
            return super.loadClass(name);

    try {
        URL myUrl = new URL(fileUrl);
        URLConnection connection = myUrl.openConnection();
        InputStream input = connection.getInputStream();
        ByteArrayOutputStream buffer = new ByteArrayOutputStream();
        int data = input.read();

        while(data != -1){
            buffer.write(data);
            data = input.read();
        }

        input.close();

        byte[] classData = buffer.toByteArray();

        return defineClass(CLASS_NAME,
                classData, 0, classData.length);

    } catch (MalformedURLException e) {
        throw new UndeclaredThrowableException(e);
    } catch (IOException e) {
        throw new UndeclaredThrowableException(e); 
    }

}
