Description

This tutorial is intended to be a hands on demonstration of integrating legacy applications into the Virtual Observatory (VObs). A brief introduction to writing a web service in Java using the Apache Axis SOAP toolkit will be given. This will then be contrasted with the approach of the Common Execution Architecture (CEA) utilising components from Astrogrid implementation, which provides a framework for easily producing applications that are fully interoperable in the VObs. Once the application has been wrapped and published, a short demonstration of how it can be called from the Astrogrid workflow and desktop will be given.

To demonstrate the principles, the tutorial will wrap a trivial unix command-line shell script, however, participants are encouraged to bring along ideas for more useful applications that they would like to see integrated. The tutors will endeavour to 'kick-start' the work, and it might be possible for attendees to be able to publish new applications into the VObs by the end of the week.
