Try something like the following:
package REAPI;
import java.util.HashMap;
import java.util.Locale;
import org.eclipse.birt.core.archive.FolderArchiveReader;
import org.eclipse.birt.core.archive.FolderArchiveWriter;
import org.eclipse.birt.core.framework.Platform;
import org.eclipse.birt.report.engine.api.EngineConfig;
import org.eclipse.birt.report.engine.api.EngineException;
import org.eclipse.birt.report.engine.api.HTMLRenderOption;
import org.eclipse.birt.report.engine.api.IRenderTask;
import org.eclipse.birt.report.engine.api.IReportDocument;
import org.eclipse.birt.report.engine.api.IReportEngine;
import org.eclipse.birt.report.engine.api.IReportEngineFactory;
import org.eclipse.birt.report.engine.api.IReportRunnable;
import org.eclipse.birt.report.engine.api.IRunTask;
import org.eclipse.birt.report.engine.api.PDFRenderOption;
import com.lowagie.text.pdf.PdfReader;
public class RunThenRenderFolderArchive {
public void runReport() throws EngineException
{
IReportEngine engine=null;
EngineConfig config = null;
IReportDocument document = null;
try{
config = new EngineConfig( );
config.setBIRTHome("C:\\birt\\birt-runtime-2_6_1\\birt-runtime-2_6_1\\reportEngine");
Platform.startup( config );
IReportEngineFactory factory = (IReportEngineFactory) Platform
.createFactoryObject(
IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
engine = factory.createReportEngine( config );
FolderArchiveWriter faw = new
FolderArchiveWriter("c:/test/myfolderarchive");
FolderArchiveReader far = new
FolderArchiveReader("c:/test/myfolderarchive");
IReportRunnable design = null;
design = engine.openReportDesign("Reports/TopNPercent.rptdesign");
IRunTask task = engine.createRunTask(design);
task.setLocale(new Locale("en", "US"));
task.run(faw);
task.close();
document = engine.openReportDocument(far.getName(), far, new HashMap(
));
//HTMLRenderOption options = new HTMLRenderOption();
//options.setOutputFormat("ppt");
//options.setOutputFileName("output/resample/topnpercent.ppt");
//options.setSupportedImageFormats("PNG;GIF;JPG;BMP;SWF;SVG");
PDFRenderOption options = new PDFRenderOption();
options.setOutputFileName("output/resample/topnpercentFA.pdf");
options.setOutputFormat("pdf");
IRenderTask rtask = engine.createRenderTask(document);
rtask.setLocale(new Locale("en", "US"));
rtask.setRenderOption(options);
rtask.render();
rtask.close();
document.close();
engine.destroy();
System.out.println("Finished");
}catch( Exception ex){
ex.printStackTrace();
}
finally
{
Platform.shutdown( );
System.out.println("Finished");
}
}
/**
* @param args
*/
public static void main(String[] args) {
try
{
RunThenRenderFolderArchive ex = new RunThenRenderFolderArchive( );
ex.runReport();
}
catch ( Exception e )
{
e.printStackTrace();
}
}
}

Jan,
I do not know of a way to write the rptdoc in memory unless you wanted
to use something like a MappedByteBuffer.
The folder writer is writing the contents of the rptdocument, so you
will probably need to do a dropStream first.

Jan,
Cool example. You should put this on the dev share at birt-exchange.org
to get feedback.

However, I cannot assure that everything works with it! Especially the listStreams:relativePath. String method remains untested since all my tests return an empty list here (also when using FolderArchive). So I only return any stream that contains the relativePath String at this point without knowing if this is a correct behavior.
