I recently attended T-Systems' Gen Day in Vienna. The first of the presentations was CoolProfs' WebServices Presentation. Rogier van Applien introdced web services, what they were and why people need an SOA. Putting it simply, interconnections between systems can get very messy and introducing an ESB fixes that BUT how does Gen interconnect with other service-based applications both in the consumption and exposition of web services ?
This presentation concentrated on the consumption of Web Services by the Web Services Connector by CoolProfs. Effectively the product constructs the EABs for you via a "wizard" approach, helping you do the view mapping and assisting with the generation. The demonstration used a live web service available freely on the internet and integrated it into a small Gen test harness (also generated by the product). The product takes the WSDL file of the web service, allows the developer to select the impirt and export views to match up and then auto creates the EAB (Java only at the moment, but we are told that other languages may appear in time) and a test harness.
The demonstration showed that with a little ingenuity its possible to consume web services easily and quickly. The discussion that ensued afterward also showed that people need to consume web services from other languages such as COBOL and other platforms such as Unix and mainframe – lets hope that the facilities for that appear soon.
