| 如果你曾用VB编写文件上传的组件的话，那么用JAVA编写文件上传的JAVABEAN十分容易。 下面的例子只是一个简版 package yuanyifileup; import java.io.*; import java.util.*; import javax.servlet.*; import javax.servlet.http.*; import javax.servlet.jsp.PageContext; public class yuanyifileup { private ServletRequest request; private ServletResponse response; private ServletConfig config; ServletInputStream DATA; int FormSize; File f1; FileOutputStream os; DataInputStream is; String filename; byte[] b; byte t; boolean flag=false; public yuanyifileup() { } public void initialize(ServletConfig config,HttpServletRequest request,HttpServletResponse response) throws IOException { this.request=request; this.response=response; this.config=config; DATA = request.getInputStream(); FormSize=request.getContentLength(); } public void initialize(PageContext pageContext) throws IOException { request=pageContext.getRequest(); response=pageContext.getResponse(); config=pageContext.getServletConfig(); DATA = request.getInputStream(); |
