BIRT report running generates NoClassDefFoundError

I created simple app to generate pdf report using Eclipse BIRT. I loaded jars from ReportEngine folder into project build path. Code looks like this:

EngineConfig config;
try{
    config = new EngineConfig( );
    config.setEngineHome( "C:\\birt-runtime-2_6_2\\birt-runtime-2_6_2\\ReportEngine" );
    config.setLogConfig("c:/temp", Level.FINE);
    ReportEngine engine = new ReportEngine(config);
    engine.changeLogLevel( Level.WARNING );
    String name = "C:\\Users\\Djordje\\EclipseProjects\\ReportingApp\\new_report.rptdesign";
    IReportRunnable report = engine.openReportDesign(new FileInputStream(name  ));
    PDFRenderOption pdf = new PDFRenderOption();
    pdf.setOutputFormat("pdf");
    pdf.setOption(PDFRenderOption.PAGE_OVERFLOW, Integer.valueOf(PDFRenderOption.OUTPUT_TO_MULTIPLE_PAGES));
    pdf.setOption( IRenderOption.HTML_PAGINATION, Boolean.FALSE );
    pdf.setOutputFileName("D:/djole" +".pdf");
    IRunAndRenderTask task  = engine.createRunAndRenderTask(report);
    task.setRenderOption(pdf);
    task.run();
}catch ( Exception e1 ){
}

And here is the error I get when I run the project:

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/birt/report/engine/api/IRenderOption

    at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 7 more

Could someone tell me what am I doing wrong, and is there any tutorial for developing code for running report on desktop app?

Solved it by using earlier version of birt_runtime, 4.4.1 to be specific. Thanks to triplem for all the effort.
