There should be an API to convert from a binary name (the name used in
reflection and Class.forName()) to a canonical name (the name used in
Java source code). In particular, for inner classes, the names aren't
the same.

Here's a sample implementation

    public static String canonicalNameOf(Class cls) {
StringBuffer buf = new StringBuffer(cls.getName());
Class declaringClass = cls;
while ((declaringClass = declaringClass.getDeclaringClass()) != null) {
            String declaringClassName = declaringClass.getName();
            buf.setCharAt(declaringClassName.length(), '.');
}
     return buf.toString();
    }
