OutputFormat NotSupported in Birt Report Engine API

Question

我想在Eclipse Indigo中将以前设计的BIRT报告呈现为HTML。我使用的是BIRT 4.2.1。当我在普通的Java应用程序中这样做时，它运行得很好。然而，当我想从RCP应用程序中做同样的事情时，它不会。

这是我的代码:

    IRunAndRenderTask task=null;
    IReportEngine engine=null;
    EngineConfig config = null;
    IReportRunnable design = null;
    try{
        config = new EngineConfig( );
        IReportEngineFactory factory = (IReportEngineFactory) Platform.
        createFactoryObject( IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY );
        engine = factory.createReportEngine( config );
        //use this if the report is in the bundle
        Bundle bundle = org.eclipse.core.runtime.Platform.getBundle("com.accenture.workforceplanning.ui");      
        URL url = FileLocator.find(bundle, new Path("/reports/scenarioAnalysis.rptdesign"), null);
        String rpt = FileLocator.toFileURL(url).getPath();
    //Open the report design
    design = engine.openReportDesign(rpt); 
    task = engine.createRunAndRenderTask(design);

    HTMLRenderOption options = new HTMLRenderOption();      
    options.setImageDirectory("./");
    URL url1 = FileLocator.find(bundle, new Path("/reports"), null);
    String rpt1 = FileLocator.toFileURL(url1).getPath();
    options.setOutputFileName(rpt1 +"/scenarioAnalysis.html");
    options.setOutputFormat("html");
    task.setRenderOption(options);
    task.run();
    task.close();
    engine.destroy();
    }catch( Exception ex){
        ex.printStackTrace();
    }               

当程序到达task.run()时，我得到以下错误:

对于我想要呈现的任何类型的输出格式都是相同的。

你知道我做错了什么吗?

我已经设法解决了这个问题。以防有人遇到同样的问题，这就是我所做的:我手动将所有BIRT插件添加到我的RCP应用程序产品的依赖项中(由于某种原因，没有添加所需的插件)。我仍然不知道缺失的插件是什么。但是应用程序现在运行正常
