Homework 4

There will be no implementation in this homework. Rather, you will
just write WS-I compliant WSDL files (and corresponding sample SOAP
messages) to describe our two exising mortgage services plus a third
one that I describe below. That is: one WSDL file that properly
describes the mmortgage calculator service, one that describes the
xml-to-xml transformation of homework 2, and a third described
below. All of the functionality will need to be exposed as remote
procedures using WSDL.

Note that "WS-I compliance" is key here. You are free to use the WS-I
(or any other) tools to help you with this, but be aware that the
tools can't guarantee that everything about your wsdl style fits the
WS-I recommendations, so you will have to do a little reading
also. Also, for each wsdl file you should supply a sample soap request
and response that would constitute a valid invocation of the
service. It is ok to use a tool to auto-generate this (ie a wsdl soap
analyzer), but beware that these things are incredibly buggy, so you
should double-check what they produce. For each WSDL you should do two
sample SOAP messages -- one using RPC/encoded and the other
document/literal (overlooking that rpc/encoded violates WS-I).


The third (loosely coupled) service -- this will be a service that
accepts preference information about the potential buyer and returns a
list of properties that meet their general criteria. To ensure some
variety in the solutions I won't specify all of the input and output
data. To get a flavor, though, input information would be things like
price range, number of bedrooms, house or condo, pool, etc. Output
will be describe the property: its cost, number of bedrooms, type of
property, sq.  footage, etc.

So, in summary, simply submit three .wsdl file. Within each .wsdl
put in a commented section at the end the sample SOAP file.
