Danny,
Only startup the platform once. This is an expensive operation. Every
time you wish to run a report just create a new engine task. If you are
writing a servlet take a look at this example:
http://wiki.eclipse.org/Servlet_Example_%28BIRT%29_2.1
Be sure to look at updated code at the bottom of the page.
