[GRAAP-WG] WS-Agreement and/or WS-AgreementNegotiation implementations (preferably in Java)

Hi all, I am new at this mailing list: my name is Jesus M. Movilla and I am currently interesting in negotiation process with WS. I have seen some posts in this list related to implementation of WS-Agreement but unfortunately I could not reach the urls. Can anybody tell me it they are some implementations of WS-Agreement and/or WS-AgreementNegotiation. Thank you very much in advanced! Jesús
