WebSphere An Introduction to the Webfacing Wizard Presented by: Raymond Everhart Overview • • • • • • • What Is WebSphere? What Is WebFacing? What Is View / Controller / Model? What Tools Do I Use To WebFace? How is a WebFaced Application Deployed? What Does Webfacing Do For Me? How Much Does Webfacing Cost? What Is WebSphere? • IBM’s Infrastructure Software Solution • Core Operating Environment: – WebSphere Application Server • Application Development: – WebSphere Studio • Add On Products – WebSphere Portal – WebSphere Commerce – Many More What Is WebFacing? • Delivered as a component of the iSeries toolset. • Converts DDS to Java Server Pages And Java Beans. • Allows Existing RPG/Cobol applications to be deployed on an application server. • Conversion occurs during development not at run-time. • Allows customization in DDS. What is View / Controller / Model ? • An Application Design Methodology • Logic is separated by function – View - Display Functions (Browser) – Controller - Screen Handling (Application Server) – Model - Business Logic and File I/O (Host) • WebFacing partially simulates VCM What Tools Do I Use To WebFace? • First Webfacing tools were delivered as a part of the WebSphere Development Toolkit v5.1. (WDT 5.1) • Most recent version supplied as part of WebSphere Development Studio Client v4.0 (WDSc v4.0) Service Pack 3 • Next version WDSc v5.0 available April 25, 2003 How is a WebFaced Application Deployed? • DDS is Converted to Java Server Pages and Java Beans • All of the required objects are placed in a WAR file.(Web Application Archive) • The WAR File is deployed/installed onto the Application Server.(WebSphere, Tomcat….on a xSeries, iSeries, zSeries…) What Does Webfacing Do For Me? • Allows me to add a browser based interface to an existing application in minutes. • Allows one program to support browser based clients and green-screen clients. • Allows existing staff to develop browser based applications in RPG/Cobol while learning Java. How Much Does Webfacing Cost? • User Time - WebFaced/Java applications are slower than Green-Screen applications • Interactive CPU - WebFaced applications run as interactive jobs. (300 CPW min) • Requires an Application Server – Tomcat - “Free” (You get what you pay for) – WAS Express as low as $500.00 for 20 users Summary • IBM wants you to use WebSphere. Over the next year, IBM will be spending $500 million dollars to put WebSphere based solutions in front of Small/Medium sized businesses. • IBM provides tools to iSeries users that cost thousands on other platforms. • WebFacing is an ideal entry method into the WebSphere environment.
