You can open the report design in the designer, select the master page and add the page number auto text item to the header or footer. When you run the report using Java, use a run task that creates a rpt document then use a render task to render to pdf.
Here is a sample api program. If the app continues to run after running the report you may not want to do the shutdown logic. As starting up the BIRT runtime is expensive. Do the shudown logic when your app is ending. Create the BIRT engine only once (wrap in a singleton) for all classes to use.
