iReport 导出word文档.doc格式 ?

怎么把iReport生成的报表导出为word文档格式.doc
我试了一下 只生成了报表图 没有文字和表格

-----------------------word
exporter.setParameter(JRExporterParameter.JASPER_PRINT_LIST,jasperPrintList);
exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME,"D://allreport.doc");
exporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "GGB2312");
exporter.exportReport();

ireport 导出word格式
导出word格式 在它的文档中也没有，

// String sql = "select * from cfg_static_user_relation"; 如果传SQL语句的话用该句

String ReportModel ="/test/test.jasper";

File reportFile = new File(application.getRealPath(ReportModel));

System.out.println(reportFile);
if(!reportFile.exists())
     throw new JRRuntimeException("报表绘制失败，找不到报表配置文件！");
JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());

// Connection conn=null;
// conn=JdbcConnectionFactory.getConnection();
Collection coll = UserService.generalCollecion();
JRDataSource sor = new JRBeanCollectionDataSource(coll);
System.out.println(application.getRealPath("test/1224215057359.png"));
Map parameters = new HashMap();

   parameters.put("re",application.getRealPath("test/1224215057359.png"));

// JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport ,parameters,conn);

    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport ,parameters,sor);
    JRExporter exporter = new JRRtfExporter();

    String tmpFilename = System.currentTimeMillis() + ".doc";

response.setContentType("application/msword;charset=utf-8");
response.setHeader("Content-Disposition", "attachment; filename="+tmpFilename);

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream());

    exporter.exportReport();

这样就可以导出WORD格式了
