[news.eclipse.birt] Re: setting PARENT_CLASSLOADER in birt 2.3

[kms@xxxxxxxxx (Kanu)]

OK? I have tried this. 

Here is my code:

protected void generateReport(OutputStream fos, String format) throws 
ReportException {
	IReportEngine engine = createReportEngine();
	IRenderOption options = createRenderOption(fos, format);
	IReportRunnable design = engine.openReportDesign(templateInputStream);
	createRunAndRenderTask(design, options, engine);
	destroyReportEngine(engine);
}

protected final IReportEngine createReportEngine() {
	EngineConfig config = new EngineConfig();
	IReportEngineFactory factory = (IReportEngineFactory) Platform
			.createFactoryObject(IReportEngineFactory.EXTENSION_REPORT_ENGINE_FACTORY);
	HashMap mh = (HashMap)config.getAppContext();
	mh.put(EngineConstants.APPCONTEXT_CLASSLOADER_KEY, 
StaticObjectHolder.class.getClassLoader());
	config.setAppContext(mh);
	try {
		Platform.startup( config );
	} catch (BirtException e) {
		e.printStackTrace();
	}
	return factory.createReportEngine(config);
}

protected final IRenderOption createRenderOption(OutputStream fos, String 
format) throws ReportException {
	IRenderOption options = null;
	do {
		if (format.equalsIgnoreCase(IReportViewer.HTML)) {
			options = new HTMLRenderOption();
			break;
		}
		if (format.equalsIgnoreCase(IReportViewer.PDF)) {
			options = new PDFRenderOption();
			break;
		}
		if (format.equalsIgnoreCase("xls")) {
			options = new RenderOption();
			break;
		}
		throw new ReportException("Bad Format");
	} while (false);
	options.setOutputStream(fos);
	options.setOutputFormat(format);
	return options;
}

protected final void createRunAndRenderTask(IReportRunnable design, 
IRenderOption options, IReportEngine engine)
		throws ReportException {
	IRunAndRenderTask task = engine.createRunAndRenderTask(design);
	Map params = new HashMap();
	addParams(params);
	task.setParameterValues(params);
	task.setRenderOption(options);
	try {
		task.run();
	} catch (EngineException e) {
		throw new ReportException(e.getMessage(), e);
	}
	task.close();
}

protected final void destroyReportEngine(IReportEngine engine) {
	engine.destroy();
}

But I still get the error:
