Are you running this as a servlet? What version are you using?
Have a look at this wiki page:
http://wiki.eclipse.org/Servlet_Example_%28BIRT%29_2.1

If you want to export in many formats, make sure to use a run task and
then a render task. The reason for this is that for each of the formats
you will not have to re-run the report. If you use a runandrendertask
you will have to run the report for each format.
You may want to read over this:
http://www.eclipse.org/birt/phoenix/deploy/reportEngineAPI.php
and
http://www.birt-exchange.org/org/devshare/deploying-birt-reports/1344-eclipsecon-2011-api-examples/
For Books you may want to look at
"BIRT A Field Guide to Reporting" Version 3
"Integrating and Extending BIRT" Version 3
