title: Integrate BIRT in existing webapp
body: <p>I would like to add the BIRT reporting engine to an existing webapp in Tomcat. I don't need the BIRT viewer, I really only want to be able to run the reports from a url like <code>http://localhost:8080/birt/output?__report=test.rptdesign&amp;sample=my+parameter</code> and use the different export options pdf, xls, doc, html.</p>
  
  <p>The integration guides I've found so far all include the viewer and writing my own servlets to handle different formats.</p>
  
  <p>I was hoping someone knew simply which servlet mappings from the report-engine web.xml file I needed and which jars I would need to include from the lib directory for this barebones BIRT implementation in existing webapp.</p>
