急!!JspsmartUpload上传文件出现的问题

Question

为什么不用struts里的FormFile.
第一个问题，应该是你的smartupload没有调用initialize方法.
第二个问题，应该是你的smartupload.getRequest().getParameter方法是获得
form里面其他的元素。

Answer 1

问题是我现在不知道怎么调用initialize方法,mySmartUpload.initialize(config,request,response);我不知道config从哪里来,能给个例子吗?这样形象点,谢了!

Answer 2

servlet里面是这样,定义一个类的全局变量,
private ServletConfig config;
  //Initialize global variables
  final public void init(ServletConfig config) throws ServletException {
        this.config = config;
   }

Answer 3

我加了这两句,可是还是出现上面一样的错误,在执行mySmartUpload.initialize(config,request,response);时出现了错误:

Answer 4

怎么解决在Action中的上传文件处理

Answer 5

OK了,原来在Action给smartUpload初始化错误,不需要写
private ServletConfig config;
  //Initialize global variables
  final public void init(ServletConfig config) throws ServletException {
        this.config = config;
   }
这是在severlet中的写法,而在struts中的Action中正确的写法是:
mySmartUpload.initialize(this.getServlet().getServletConfig(),request,response);这样问题就解决了.
