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;
import java.util.Iterator;
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.IGetParameterDefinitionTask;

    IReportEngine engine = null;

    public BirtEngine()
    {
        try {

            config.setBIRTHome("C:\\birtruntime\\ReportEngine");
            Platform.startup( config );
            IReportEngineFactory factory = (IReportEngineFactory) Platform.createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
            engine = factory.createReportEngine( config );

        }catch(Exception ex){
            ex.printStackTrace();

    }

    public void stopPlatform()
    {
        engine.destroy();
