  2. Outline • Introduction • Process / Plan • Accomplishments • Findings • Pitfalls • Demos • Objectives Revisited • Future Goals • Conclusion

  3. Introduction • Excellus Blue Cross Blue Shield • 450 CSRs answer 30,000 calls daily • Example: Customer Makes Claim • Membership Validation • Edit Claim • Evaluation • Pay/Deny • TIGRESS • Visual Basic 6 • Mainframe Core • Legacy Software • Need for Modular Design • Adaptability

  4. Introduction • jTIGRESS • JAVA based solution • Modular Approach • User Interface • Objects • Heterogeneous Systems and Databases • Our Scope • Presentation Layer of jTIGRESS • Provide a Proof-of-Concept of Portal Technology • IBM WebSphere Software • Findings Feed into New Architecture

  5. Process / Plan • Our Approach • 2 Phases of Technology Feasibility Exploration • Phase 1 Objectives • Defined at the beginning of Winter quarter • Phase 2 Objectives • To be defined by the beginning of Spring quarter

  6. Process / Plan • Phase 1 Objectives • Is portal technology a feasible solution? • Complexity • Inter-portlet communication • User based roles (permissions) • Compatibility with existing databases • LDAP • Performance • Efficiency • Knowledge • Tool Support • Procedures • Learning Curve

  7. Process / Plan • Phase 1 (Winter Quarter) Activities • WebSphere Software • Installation • Configuration • Portlet Development • Research (Proof-of-Concept) • Prototype development • TIGRESS Research • Source inspection

  8. Process / Plan • Roles • Team / Project Manager – Jon Ferry • Plan, Track, and Manage Activities • Interface with Client • Technical Manager – Greg McGraw • Configuration and Support Specialist • Research Documentation Manager – Jonathan Peffer • Manage Main Deliverable • Ensure Cohesiveness • Development Manager – Chris Helmeset • Ensure High Quality Designs and Applications

  12. Process / Plan • Phase 1 Deliverables • Portlet Technology Analysis Report • Overview of Technology • Learning Curve • Reference Information • Click Here • Prototypes • Deployment Files • Source Files • Click Here • Project Website • Availability of All Documentation • Click Here

  13. Accomplishments • WebSphere Environment Installed & Configured • 2 Portlet Prototypes Operational: • Simple Form Handling • Inter-portlet message passing • Interim Portlet Technology Analysis Report

  14. Findings • What are portals? • Presentation Layer to Info Systems • Contains Portlets • What are Portlets? • “Pluggable” Components • Modes • States

  15. Findings • J2EE Application Design • Portlet Application Design

  16. Findings • Architecture • Portlets • Container • Portal

  17. Findings • WebSphere Configuration • Client • Intel Pentium 4 running at 1.8GHz • 768Mb of RAM • Microsoft Windows XP Professional, Service Pack 1 • Studio Application Developer, V.5.1 • Portal Toolkit, V.5.0.2 • Server • Intel Pentium 4 running at 1.8GHz • 1024Mb of RAM • Microsoft Windows 2000 Server Edition, Service Pack 4 • Application Server Enterprise Edition, V.5.0 • Portal Server Express, V.5.0 • DB2 V.8.1

  18. Findings • Application Developer • In-line Error Checking • Type Checking • Application Templates & Wizards • Straightforward Application Creation • Server Integration • Debugging & Test Environment • Enhanced User Interface • XML, HTML, JSP

  19. Findings • Toolkit Analysis • Ease of Development • Create Default Portlet Application • Tune to Our Application • Edit JSPs, Servlets, JavaBeans, etc. • Export to .war • Portal Console Analysis • Ease of Deployment (Portal Server) • Install .war • Add to Page

  20. Pitfalls • WebSphere Configuration • Resolved: • Difficulty Meeting Hardware Requirements • Server - 1024Mb of RAM • SE Systems Administrator Transition • IBM license agreement recreated • Open: • Client’s Local Test Environment • Lack of Technical Documentation • Contact IBM Technical Rep.

  21. Demos • Simple Portlet Application • Goal: • Create and deploy simple portlet to server • Technologies: • Portlet Servlets • Java Server Pages (JSP) • Java Beans • View: • EMailerPortlet

  22. Demos • Messaging Portlet Application • Goal: • Communicate between portlets via message passing • Technologies: • Portlet Servlets w/ Events • Java Server Pages (JSP) • Java Beans • View: • MessageSenderPortlet
