Abstract:

At the dawn of the third millennium CERN 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, with extremely tight
deadlines. Eighteen months ago CERN embarked in the direction of
Enterprise JavaBeans (EJB) architecture and a Java Servlet API.
Now full production includes 1000 different users per day on a multi-lingual
system processing 300,000 electronic authorizations per year using
Oracles high performance JServer Java VM in the heart of an Oracle8i
database. This session walks through this success story, from the
early design decisions, the promises of the EJB architecture, client
vs. server-side validation, and the risks and pay-offs of going
production with such new technologies. The discussion includes practical
advice from the chief developer of this project including the implications
of each design decision, and a critical comparison of alternative
Java solutions.
