Within legacy systems, creating web services using the bottom-up, RPC pattern methodology is often the quickest means to expose exiting functionality in the legacy system. Xcentrisity Business Information Server, using XML Extensions, provides a simple mechanism to create such web services.
While a more complex example will be created later, we will use a simple data lookup for our first example. A desired company name, which may be a fragment of a name, will be provided. The desired result is the data from the 'first' record for which the company name is greater than or equal to the desired company name. (Note that the data used for the sample programs in this tutorial is excerpted from North American Numbering Plan data. The data are not complete and contain inaccuracies to render the data unsuitable for any commercial application.)
