problem compiling tuscany source code 2.0-M3, cglib library

[ytrewq2...@libero.it]

Hi,

i have to compile tuscany source found here: 
http://mirror.olnevhost.net/pub/apache/tuscany/java/sca/2.0-M3/

version 2.0-M3

but i have problem. i can't find the correct cglib class..
the problem is the all code work fine but the
generateRemoteInterface gives me a compiler error:

compiler can't find in class net.sf.cglib.core.Constants:

Constants.V1_5
Constants.ACC_PUBLIC
Constants.ACC_ABSTRACT
Constants.ACC_INTERFACE

what's the right cglib ??
thank you

this is the code where i get errors:

private static byte[] generateRemoteInterface(Class<?> serviceInterface) {
        String interfazeName = serviceInterface.getName();
        ClassWriter cw = new ClassWriter(ClassWriter.COMPUTE_MAXS);

        cw.visit(Constants.V1_5, Constants.ACC_PUBLIC + Constants.ACC_ABSTRACT 
+ Constants.ACC_INTERFACE, interfazeName
            .replace('.', '/'), null, "java/lang/Object", new String[] 
{"java/rmi/Remote"});
