Overview

HATS interoperability with WebFacing applications provides the ability to perform data description specification (DDS) display file source member transformation, as well as 5250 data stream transformation, within the same Web application. This function is particularly useful for those who have built a DDS source-based transformation application, using the WebFacing tool, that need to interact with a host application that has been transformed using the HATS tool. This function is also useful for HATS users who want to take advantage of transformation, based on DDS display file source members, provided by the WebFacing tool.

Interoperability, in this context, means that a single HATS Web application interoperates with, or works along side, a single WebFacing application. The combined Web application has the capabilities of both tools, with some limitations, but the capabilities are cleanly separated within the Web application. To create a combined Web application, a single HATS Web project is linked with a single WebFacing project and packaged into a single enterprise application, or .ear file. This enterprise application contains the runtimes of both products, along with a common runtime component that is used to create and interact with a shared connection to the 5250 backend host.
