Preparing for the end of Java 7: How it affects integrated web application server (June 26, 2018)

End of support for Java 7 is scheduled for September 2019.  In addition, Liberty - which integrated web application server (IAS) is based on - is set to end support for Java 7 at that time.  What does that mean for your current IAS installations?

End of support for Java 7 means you can’t get updates or fixes for Java problems such as security vulnerabilities. Staying on the Java 7 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 supported by Liberty — Java SE 8. 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.

Features and benefits

The integrated web application server for IBM i is a composable, dynamic, application server for hosting Java applications during development, test, and production.


  • Simple to configure -- The integrated web application server provides an easy to use web administrative GUI front-end that allows you to manage and monitor the server and any deployed applications.

  • Support for many Java technologies.


  • No up-front costs -- The application server is part of the operating system, so you can get services up and running and show tangible results fast.
  • Advanced capabilities -- A comprehensive and proven portfolio of middleware products from the IBM WebSphere family.
  • Focus on core capabilities -- Solution providers do not require new skills or tools for the deployment of Java applications to the application server.
