All Violate the VE Principles
New Players have to write code to join:
Violates all of the principles.
WS Operations must agree with process description
Process is always a state diagram
Exceptions handled by standard mechanisms such as
catch and throw
compensating transaction
Process must be maintained and controled by a central party - even for WSCI "P2P" approach.
Not really any better than RPCs.
