You must have heard this term earlier and might be searching for an answer on the Internet. Well, we are going to answer this for you.
Web service is defined as a program that talks about “something” on the web. The integrated web service for IBMi is a term that describes the following technologies for IBM AS400 RPG:
- The IWS Server
- The IWS clients for ILE
The IWS server serves as a fully functional server where ILE-based program entities can be installed as web services.
The IWS client for ILE allows the application to act as web services clients by generating RPG, C, and C++ counterfoils that an ILE program can use. The counterfoils remove the complications of the web service protocols by managing to serialize and deserialize service requests and responses.
Web services provide the ability to represent the database to external developers through APIs and Web services. Even though that thought takes a shiver down the spine of many RPG AS400 developers who learned the proprietary ways of the AS/400, multi-platform incorporation is the latest development path. The stress on integration cannot be exaggerated.
In the era of the Internet, things are changing rapidly, and businesses worldwide are continuously watching at what can be done to make web services modern.
Since IWS’s introduction as part of the V5R4 operating system in 2006, it has been upgraded many times. The most notable enhancement in this series was – SOAP to REST services. Nowadays, most web services development in IBM as400 RPG shops uses REST services, but earlier, the web services were developed using SOAP, and they quickly outnumbered the new web services.
Anyone following the progress of web services must have seen RESTful architecture rise over traditional SOAP architecture. Web development services providers and particularly mobile-based app developing companies, have welcomed REST. To keep up with the increasing demand, Krengel Technologies had launched the 3.2 version of its RPG-XML Suite. The latest version can deliver web services to IBM as400 RPG customers.
The RPG-XML Suite is a collection of programs, commands, and procedures that allow RPG AS400 developers to work XML and JSON, offer web services, and consume IWS remotely.
Krengel developed an RPG-XML suite for RPG AS400 developers involved in developing web services in RPG and JAVA without a well-packaged development toolset.
