Good, I'm glad that's clear :-) It may be that I have misunderstood the discussion but my concerns were the following - talk of defining the interface in SOAP and embedding in a servlet container - talk of clustering facades for non clustered implementations While both of these may be important from an implementation and deployment perspective, neither is relevant to the service interface being defined. The priority for now is to work out the requirements for this interface and, while we should keep the implementation details in mind, these details should not distract us from the specification of the interface.
