JSP环境中用
mySmartUpload.initialize(pageContext);

servlet中用
SmartUpload.initialize(config,request,response);

SmartUpload.initialize(config,request,response); 中的config,request,response
private ServletConfig config;
private ServletResponse response;
PageContext pageContext;
ServletRequest request;
这样定义对话为什么不对啊?

// Initialization
mySmartUpload.initialize(pageContext);

// Upload
mySmartUpload.upload();

String path = mySmartUpload.getRequest().getParameter("PATH")

mySmartUpload.initialize(pageContext);与mySmartUpload.initialize(config,request,response);关系？

private ServletConfig config;
private String[] fileName;

final public void init(ServletConfig config) throws ServletException {

SmartUpload mySmartUpload=new SmartUpload();
// Initialization
mySmartUpload.initialize(config,request,response);
String operation=mySmartUpload.getRequest().getParameter("operation").trim();
