Introducing HATS LE

Welcome to IBM(R) WebSphere(R) Host Access Transformation Services Limited Edition (HATS LE) Version 5 (V5). With HATS LE you can quickly transform your 5250 host application into a Web application and make it available to your users through their browsers. HATS LE helps you protect your investment in legacy applications while presenting them to your end users--customers, suppliers, and internal staff--as Web applications accessible from their workstations.

HATS LE transforms the screens of a host application into Web pages that are part of a WebSphere application running on a Web server. End users access the pages from their Web browsers and use the pages to send and receive data from the host application. The end users might not even be aware that they are interacting with a host application; from their perspective, everything is taking place on the Web server.

Host Access Transformation Services Limited Edition is a functional subset of Host Access Transformation Services (HATS). HATS is a toolkit for IBM WebSphere Studio, and enables you to customize thoroughly the Web applications that transform your legacy host applications and make them available on your users' workstations. You can upgrade your HATS LE application to a HATS application, adding further customization and abilities to produce the function and ease of use that you want. HATS' rules-based transformation of host screens and support for iterative development mean you can add features as you are ready. With HATS you can:
