Starting with Version 7.1, the IBM® WebFacing Tool is installed as a part of Host Access Transformation Services (HATS). Please refer to the Host Access Transformation Services Install Guide to learn about the prerequisite products that you need to successfully install the IBM WebFacing Tool.
Application bridge
The application bridge is of great value when enhancing your i5/OS® application by allowing you to implement part of it as a Web application such as Enterprise Generation Language (EGL), and modernizing other parts with WebFacing or HATS. It allows WebFacing to transfer control and data to and from other Web applications such as EGL, giving you the ability to combine HATS, WebFacing and EGL into a single application. Please refer to Using the WebFacing application bridge to interoperate with other Web applications to integrate with other Web applications for further information on WebFacing application bridge.
i5/OS integrated Web application server
WebFacing applications can be deployed to the i5/OS integrated Web application server. You can use the i5/OS integrated Web application server if you are deploying WebFacing Web applications and have limited i5/OS system resources that cannot optimally run the WebSphere® Application Server. Note that this configuration does not support high availability and failover.
