		// 此处根据您具体情况定
	        ResultSet rs = getJdbcManager().executeQuery("select login,last_name from user_table");
	        while (rs.next()) {
	            HSSFRow row = sheet.createRow(i);
	            for(short j=1;j<3;j++){
	            	HSSFCell cell = row.createCell((short)(j-1));
	            	cell.setEncoding(HSSFCell.ENCODING_UTF_16);
	            	cell.setCellValue(rs.getString(j));

/*此处可以直接 inject response */
	    Response response = getResponse();
	    try{
	    	 OutputStream _out = response.getOutputStream("application/vnd.ms-excel");
		    	//getResponse().getOutputStream("application/vnd.ms-excel");
			wb.write(_out);

			_out.close();
