CHAPTER17The Human Task Service

When services are long running—for example, because human involvement is required—we at some point move from composite service orchestration to the realm of process execution. What we still may be lacking in our composite applications—to have them really face the business challenges we know will be thrown at us—is something we could call the “ghost in the machine.” After all is said and done by the service components discussed so far—and that is quite a lot, let’s make no mistake about that—there is still a category of activities that we do not have the solution for yet. Some things simply cannot be done by fully ...
