200分求大家解决jasperreport通过APPLET客户端打印
本帖最后由 tangyu477 于 2012-07-10 09:01:30 编辑 jasperreport通过APPLET客户端打印，出现了报表样式丢失，
请问谁遇到并解决了呢，希望没遇到的，高手们也给分析分析，直接上代码好了、
Action
public String PrintStanding() throws Exception{
String querydate=request.getParameter("querydate");
String storeid=request.getParameter("storeId");
String storeStatus=request.getParameter("storeStatus");
String goodsType=request.getParameter("goodsType");
String goodsId=request.getParameter("goodsId");
String printUser=request.getParameter("printUser");
String StoreName=request.getParameter("StoreName");
System.out.println();
Map<String, Object> waremap=new HashMap<String, Object>();
waremap.put("goodsType", goodsType);
waremap.put("goodsId", goodsId);
waremap.put("storeid", storeid);
waremap.put("storeStatus", storeStatus);
List<WarehouseGoods> list=warehouseInService.printWareStanding(waremap);
Map<String, Object> parameter = new HashMap<String, Object>();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
parameter.put("QUERY_TIME",sdf.parse(querydate));
parameter.put("CREATE_USER",printUser);
parameter.put("STORE_NAME",StoreName);
//对数据和打印模板进行填充
response.setContentType("application/octet-stream");
response.setBufferSize(8986000);
ServletOutputStream ouputStream = response.getOutputStream();
//JasperReport jrt = JasperCompileManager.compileReport(request.getRealPath(STANDING_PRINT_MODEL_FILE));// 编译报表格式
JRDataSource dataSource = new JRBeanCollectionDataSource(list);
JasperPrint jpt = JasperFillManager.fillReport(request.getRealPath(STANDING_PRINT_MODEL_FILE), parameter,dataSource);// 匹配数据源，生成JasperPrint
//JasperPrintManager.printReport(report, false);//此处为服务器打印，可以看见报表样式未丢失,但不符合需求，需客户端打印
//打印数据输出
ObjectOutputStream oos = new ObjectOutputStream(ouputStream);
oos.writeObject(jpt);
oos.flush();
oos.close();
return null;
