Kishore,
Take a look at the servlet example
http://wiki.eclipse.org/Servlet_Example_%28BIRT%29_2.1
In the comments is a 2.2 example which should work fine with 2.3+

Understood, but If you want to package the birt runtime in a webapp it
is probably better to use the plaformservletcontext. If you do not want
to do that reportrunner should be fine.

What are you setting BIRT_HOME to?
It has to be a hard directory if you are using the PlatformFileContext.
The directory must contain the birt plugins directory and a
configuration directory containing the config.ini. You can write your
own Platform Context or use the PlatformServletContext to do different
deployments.

I am not sure what is happening here, But ideally what you want to do
is startup the platform only once when your application starts up. Get
the engine and for each new run just create an engine task to run and
render the report. I believe reportrunner is just a sample and starts
up the platform and then shuts it down. In a web app that is a bad idea.
