Question

smartupload的问题，求助

Simple01.html

<form action="Simple01.jsp" method="post" ENCTYPE="multipart/form=data">
输入名称：<input type="text" name="ino"><br>
选择要上传的图片：
<input type="file" name="pic">
<input type="submit" value="上传">
</form>
----------------------------------------------------
Simple01.jsp
<%@ page contentType="text/html;charset=gb2312" %>
<jsp:useBean id="smart" scope="page" class="com.jspsmart.upload.SmartUpload"/>
<%
smart.initialize(pageContext);
smart.upload();
smart.save("/upload");
%>
<%
String name = smart.getRequest().getParameter("ino");
%>
<h1><%=name%></h1>
------------------------------------------------------------------------

可是图片没有出现在文件夹里，而且取不到值，在Simple01.jsp中显示的是null。这是怎么回事儿，这个代码我看了很多遍了，应该没有问题，会不会是smartupload.jar有问题？

现在我又试着把Simple01.jsp改一下，如下：
<%@ page contentType="text/html;charset=gb2312" %>
<jsp:useBean id="smart" scope="page" class="com.jspsmart.upload.SmartUpload"/>
<%
smart.initialize(pageContext);
smart.upload();
String ext = smart.getFiles().getFile(0).getFileExt();
%>
<%
String name = smart.getRequest().getParameter("ino");
%>
<h1><%=name+"."+ext%></h1>

改完就报错了，报错如下:

HTTP Status 500 -

Answer 1

mySmartUpload.initialize(pageContext);
mySmartUpload.upload();
com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(0);

String path = request.getSession().getServletContext().getRealPath("/upload");
myFile.saveAs(path + "/" + 文件名 + "." + myFile.getFileExt());
