This talk is about the experience of replacing an inhomogeneous mix of technologies for a complex commercial web application with the leading edge integrated all-in-one environment WebVelocity.

WebVelocity is a development and deployment environment to easily and quickly develop both complex and simple commercial web applications. It is a fully in-browser development environment to deploy in or out of the cloud. It is built on and extends the open-source frameworks Seaside and Glorp.

The presented application is part of a commercial air pilot training system, handling the online exam training (theoretical part) both for students and for exam administration. It was initially built using Java Web Start and J2EE with a XML database and a large number of technologies like HTML/JavaScript, Java, XML, Ruby, Flex, Postgres and further frameworks, some of which were discontinued in the course of the project.

Ernest will share his experiences in using WebVelocity for rewriting this online system and deploying it in a staging environment. He’ll demonstrate how WebVelocity provides an interactive all-in-one environment that helped him to improve productivity, performance, maintainability and reliability. Maintainability was also improved by WebVelocity being a commercially backed environment.
