Generate BIRT PDFs from a Netbeans application

Question

I have created a report with the Eclipse BIRT plugin for Eclipse and want to create a PDF from a console application (I use Netbeans to create this)

I have looked around the documentation but I can't really get anything to work. How can I call BIRT to generate the PDF from the .rptdesign?

I got most of this code from the eclipse site but I can't seem to find it now. I commented out my implementation specific code below but the rest should be usable/editable for you. All of the imports came in the normal birt runtime. The printReport method below generates a PDF from a report url:

import java.io.ByteArrayOutputStream;
import java.util.Collection;
