Integrated Web Services for IBM i - Web services made easy

Integrated Web Services for i enables Integrated Language Environment (ILE) applications to play in the web services and Service Oriented Architecture (SOA) arena with very little effort, knowledge and resources. The convergence of web service and IBM i technologies can help enterprises liberate core business assets by making it easier to enrich, modernize, extend and reuse them well beyond their original scope of design.

In today’s increasingly interconnected world, application programming interfaces (APIs) are becoming the digital reflection of an organization. Whether you call it web APIs or web services, getting started on IBM i is easier than ever with the Integrated Web Services for i. The bottom line is that flexible businesses requires flexible IT, and the path to flexible IT is web services and SOA.

The end of Java SE 6: How it affects the integrated web services server
Perhaps you’ve seen some of the recent Java SE 6 end of support messages from IBM and wondered about the effect on integrated web services server (IWS) for IBM i. In short, public updates for Java SE 6 are no longer available, and the end of support in IBM Liberty (which IWS is based on) is set for September 2017. But what does that mean for your current IWS installations?

End of support for Java SE 6 means you can’t get updates or fixes for Java problems such as security vulnerabilities. Staying on the Java SE 6 level could leave your applications exposed to future issues. To ensure your applications are running in a supported environment for years to come, we recommend moving to the latest Java — Java SE 8. Java SE 7 is also an option, but its support only runs until 2019. You can update the Java version for a server by using the IBM Web Administration GUI for i. Select the server, then click on the Server->Properties link and you will be able to select a Java version from a selection list. If you do not see a suitable version, you will need to install the licensed product that contains the Java version you desire. More information on Java on IBM i may be found on IBM developerWorks.

Users of Integrated Web Services server (IWS) versions 1.3 and 1.5 should move to latest version
Versions 1.3 and 1.5 of the IWS server will not be supported beyond IBM i 7.2. In addition, if the IWS server is running in Integrated Application Server (IAS) 7.1, you will need to transition to IAS server 8.1 by creating a new IWS server (version 1.5) and copying the web services from the old server to the new server using the and scripts. The WSDL between the IAS servers does not change, giving you time to transition to the latest version of the IWS server.

Features and benefits

The IBM i operating system integrates software technologies that support the externalization of an Integrated Language Environment (ILE) program object as web services (also known as web APIs) and the consumption of services by an ILE program object. These technologies are the Integrated Web Services server and the Integrated Web Services client for ILE.

Integrated web services server -- The web service engine or run time is integrated in IBM i and is used to externalize ILE business logic as a service. This integration opens the IBM i system to a variety of client implementations, including RPG, COBOL, C, C++, Java™, .NET, PHP, ESB, and Web 2.0.


  • Easy to use
    The web administrative GUI front-end that allows you to manage and monitor the server and any deployed web services.
  • Leading edge
    The web services server is built on the powerful, yet lightweight, integrated application server and best-of-breed technologies in support of SOAP and RESTful web services.
  • Small footprint
    Uses ILE programming architecture for minimal consumption of IBM i resources.


  • Get started with no up-front costs
    The integrated web services is part of the operating system, so you can get services up and running and show tangible results fast.
  • Focus on your core capabilities
    Solution providers do not require new skills or tools for the deployment of ILE-based web services and thus can focus efforts on building differentiated value for customers rather than rewriting core infrastructure.

Integrated web services client for ILE -- The web services client for ILE delivers a mechanism to generate service artifacts and allow ILE (RPG, COBOL, C, and C++) to act as a services consumer. It can call a variety of web service implementations, including RPG, COBOL, C, C++, Java, PHP, .NET, ESB, etc.
