解决方案二：

解决方案三：
初始化是不是有问题？空指针啊，27:myUpload.initialize(pageContext);28:29:if(myUpload.getRequest().getParameter("isReUpload").equals("1")){确定了isReUpload的作用域了没？
解决方案四：
把if(myUpload.getRequest().getParameter("isReUpload").equals("1"))之后能运行
解决方案五：
就不能按格式来放代码？这样看好累啊··
解决方案六：
我发现是因为smartupload不能传递radio的值造成的，请问有没有办法传递radio的值？
解决方案七：
空指针呢
