At the dawn of the third millennium CERN (the world's largest physics
research center and inventor of the Web-Wide-Web) is embarking on
its largest construction ever. Physicists worldwide require web
based access to generate, route and authorize a multitude of electronic
documents (such as purchase orders, transport requests etc ) with
extremely tight deadlines.
One year ago we embarked in the direction of Enterprise JavaBeansTM
(EJB) architecture and a JavaTM Servlet API. Now we are in full
production with 1000 different users per day, a multi-lingual system
processing 300,000 electronic authorizations per year, electronic
Java technology-based "documents" routed by Oracle Workflow, and
communication between the documents and the workflow engine running
in the Java programming language in the heart of an Oracle 8i database.
We will walk you thru this success story from the early design
decisions (applets vs servlets), the promises of the EJB architecture,
worries about interactivity, and the risks and pay-offs of going
production with such new technologies. Practical advice will be
given from the chief developer of this project from the implications
of each design decision, to the final load balancing of 1000s of
users across 20 Java virtual machines.
