如何用代码导出报表？

[b]1.创建报表引擎[/b]
[b]2.创建设计处理器[/b]

   reportRunnable = reportEngine.openReportDesign(filePath);
	 	 designHandle = (ReportDesignHandle) reportRunnable.getDesignHandle( ); 

[b]3.导出[/b]
IRunAndRenderTask task = reportEngine.createRunAndRenderTask(reportRunnable);
[b] a.html[/b]

             
	        HTMLServerImageHandler imageHandler = new HTMLServerImageHandler();
			HTMLRenderOption option = new HTMLRenderOption();
			option.setOutputFileName(savePath+"/"+fileName); 
			option.setImageHandler(imageHandler); 
			option.setActionHandler(new HTMLActionHandler());
			option.setOutputFormat("html");

			HTMLRenderContext renderContext = new HTMLRenderContext();
			renderContext.SetRenderOption(option);
			renderContext.setSupportedImageFormats("JPG;PNG;BMP;SVG");
			String imgPath = fileName.substring(0,fileName.indexOf(".")); 
			renderContext.setImageDirectory(savePath+"/"+imgPath+".files");
			renderContext.setBaseImageURL("./"+imgPath+".files");
			HashMap<Object, Object> contextMap = new HashMap<Object, Object>();
			contextMap.put( EngineConstants.APPCONTEXT_HTML_RENDER_CONTEXT, renderContext );
			task.setAppContext(contextMap);
			option.setEmbeddable(true);
			task.setRenderOption(option); 
			task.run(); 

[b]b.pdf[/b]

       
	   PDFRenderContext renderContext = new PDFRenderContext();
			renderContext.setBaseURL(""); 
			HashMap<Object, Object> contextMap = new HashMap<Object, Object>();
			contextMap.put(EngineConstants.APPCONTEXT_PDF_RENDER_CONTEXT,renderContext);
			task.setAppContext(contextMap);
			RenderOptionBase options = new RenderOptionBase(); 
			options.setOutputFileName(savePath+"/"+fileName); 
			options.setOutputFormat("pdf"); 
			options.setActionHandler(new HTMLActionHandler());
			task.setRenderOption(options);
			task.run(); 

[b]c.xls[/b]

	    Map<Object, Object> xlsMap = new HashMap<Object, Object>();
			xlsMap.put("fixed_column_width", Integer.valueOf(30));
			xlsMap.put("show_grid_lines", Boolean.valueOf(false));
			engineConfig.setEmitterConfiguration("xls", xlsMap);

			RenderOptionBase options = new RenderOptionBase();
			options.setOutputFormat("xls");
			options.setOutputFileName(filePath);
			EXCELRenderOption excelOptions = new EXCELRenderOption(options);

			excelOptions.setSupportedImageFormats("JPG;PNG;BMP;SVG");
			HTMLServerImageHandler imageHandler = new HTMLServerImageHandler();
			excelOptions.setImageHandler(imageHandler);
			task.setRenderOption(excelOptions); 

[b]4.关闭任务[/b]
task.close();
[b]5.关闭报表[/b]
reportEngine.shutdown();
　Platform.shutdown();
