How to access reports from external jar

ssen

I have deployed BIRT as a web app and can access and display reports from within the war file using the standard URL e.g.

request.getContextPath( ) + "/frameset?__report=test.rptdesign&sample=my+parameter

How would I access a report located in a jar file outside
the war - e.g. located in lib/ext and can be accessed using
the standard resource loading mechanism that we have
in a j2ee app.

Can we pass a report document as a stream (getResourceAsStream) to the ViewerServlet?

Thanks for any info on this.
