Pilot Project Goals
  • Short-Term/Immediate Goals
  • Provide alternative GUI for Requisition entry
  • Post new Requisitions
  • Clone existing Requisition and post as new
  • Modify Requisitions
  • Print Requisitions
  • Do not disturb existing application
  • Post/update to existing USAS data files
  • Use existing OpenVMS/USAS security model
  • Focus on casual/infrequent user

3
Pilot Project Goals
  • Project Requirements/Longer Term Goals
  • Design framework for web-enabling other state
    software functions
  • Plan for future for platform migration
  • Use standard technologies (XML, SOAP, RPC, etc.)
  • Allow for other interfaces e.g. native GUI
    client
  • Ancillary Goals
  • Keep costs low (hardware, licensing operating)
  • Use Open Source or free tools when possible
  • Support, but dont limit to, current OSs and
    hardware
  • Reduce dependency on proprietary OSs and software

4
Project Status
  • HP Consultants
  • Designed architecture and framework
  • Implemented first (Requisition) webapp and SOAP
    service
  • Have delivered final version
  • SSDT
  • Backend RPC on OpenVMS using existing routines
  • Completing webapp and SOAP service
  • Clean up UI, fixing remaining problems
  • Prepare for configuration/deployment
  • Expected Release date May 2003
  • (Note There are 31 days in May)

5
New Technologies
  • For OpenVMS Server
  • USP (Universal Service Provider)
  • Free product from HP
  • Provides RPC (Remote Procedure Call)
  • Permits existing 3GL (e.g. COBOL) to be called by
    remote clients
  • Handles VMS process creation and management
  • Allows creation of a process similar to an
    interactive user with appropriate security
    context
  • Provides native Java classes for remote clients

6
New Technologies
  • For Web Server
  • Java 2
  • J2EE web container (e.g. Tomcat)
  • JSP, Servlets, etc
  • For SOAP server
  • Apache Axis
  • Entire application will be native Java

7
Requirements
  • OpenVMS/Alpha 7.3-1 server
  • USP V6.1
  • Web/SOAP server
  • Java 1.4.1 (or higher)
  • Tomcat 4.0.4 (or higher)
  • Any web server with Servlet Connector)
  • SSDT intends to support
  • OpenVMS with Apache Web Server
  • Linux with Apache
  • Windows 2000 (IIS or Apache web server)
  • SSDT has provided additional details and sources
    for software
  • See http//ssdt.oecn.k12.oh.us/rpcweb/

Why Java J2EE?
  • Advantages of Java and Java 2 Enterprise Edition
  • Low cost
  • No licensing for development or run-time
    environments
  • Open source and commercial alternatives available
  • Platform independence
  • Runs anywhere
  • Provides migration from OpenVMS
  • Does not limit hardware or OS choices
  • Broad industry and standards support
