Cannot use web service solution for TransMaster?

I thought that the web service solution will not be am acceptable solution for communicating with Transmaster. The web service solution requires Transmaster to be able to handle SOAP but the assignment never says that Transmaster will have that capability. So using the web service solution would assume change in the requirements. It is hard to know what is acceptable and what is not. Can some of you who have passed part II give us some idea on this? Thanks.

Chen,
the requirement does NOT mention anything about the new Transmaster design and hence leaves it open ended...You as an architect are free to assume anything as long as properly documented...The exam also does not constrain u w.r.t budget and/or time. Yes, SOAP might provide ONE implementation of the Transmaster service as web service. Given the abundance of framworks/patterns, u can defer the implementation of the provider till run time even, which might as well be "SOAP-LESS" invocation. One such framework thats kinda steady and supports the latest AXIS version is the WSIF framework allowing dynamic invocation as well....

These are just some of the tools to ease your migration to the web services environment easy...Document what u'd likta use in this airline specific case and explain the reason for ur choice.

Sun wouldn't penalize u for using state-of-the-art technology if you find a compelling reason to do so and feel would best satisfy the client's needs. To be frank, except for the network latency factor, i'd likta see the Transmaster component evolve as a web service. And with frameworks like WSIF, the session management as well as the use of RMI-IIOP istead of xml marshalling/demarshalling during the web services call would adequately increase the response time and hence its acceptibilty...

Hope that helps.
