Thanks for you answer.
I know how to create a xml file with Tpye IWDResource and use download() method to download that file.
But I want show it with a OfficeControl in a view . I read a xml file local then transform to byte[] and binding with OfficeControl . But it's does not work.
Then I used a Third Tool names POI,it can create a Excel file. I transform it to byte[] and binding with OfficeControl,it's does not work .And it has a error:
ERRO|20080424100407|KHFA.OfficeCompView.OfficeControl_5140|CIOS_GeneralDocumentContainer_Acf::|OleLoad|HRESULT=-2147221164(没有注册类别)
I do't know why?
Code:
          ByteArrayOutputStream os = new ByteArrayOutputStream();
          HSSFWorkbook wb = null;
          wb = new HSSFWorkbook();
          HSSFSheet s = wb.createSheet();
          wb.setSheetName(0, "Matrix");
          HSSFRow row = s.createRow(0);
          HSSFCell cell = row.createCell((short) 0);
          cell.setCellValue("POI test");
          try {
               wb.write(os);
          } catch (IOException e) {
               e.printStackTrace();
          try {
               ByteArrayInputStream is = new ByteArrayInputStream(os.toByteArray());
               IWDResource resource = WDResourceFactory.createCachedResource(os
                         .toByteArray(), "1", WDWebResourceType.XLS);
               wdContext.currentContextElement().setResource(resource);
               INodeBinaryElement element = wdContext.nodeNodeBinary().createAndAddNodeBinaryElement();
               element.setBinaryResource(os.toByteArray());
          } catch (Exception e) {
               e.printStackTrace();
