With Host Access Transformation Service (HATS), you can create Web applications and rich-client applications that provide an easy-to-use GUI for your 3270 applications running on IBM System z platforms and your 5250 applications running on i5/OS. HATS Web applications, including portlets, can be developed with an interface that matches your company's Web or portal pages, and your users can access them through their Web browsers. HATS rich-client applications can be developed to run in an Eclipse rich-client platform implementation or in the IBM Lotus Expeditor Client to provide native client applications targeted for a user's desktop.
With HATS, you can also create Web services that provide standard programming interfaces to business logic and transactions contained within host applications. These Web services can be reused as building blocks to develop new internal applications or to integrate with applications outside your enterprise. Your host-based business tasks can then be included in your service orien
