enctype="multipart/form-data"同意楼上的。问题就在这里。
问题是我去掉了enctype="multipart/form-data"还是得不到URL,而且其它text类别的input
也是不行啊。
输入文件：
<form action="dopicture.jsp"  method="post" name="form1">
  <br>
  <input type="text" name="a">
  <input type="file" name="file">
  <input type="submit" name="Submit" value="Submit">
</form>
输出文件：
String x=(String)request.getParameter("file");
String y=(String)request.getParameter("a");
out.println(x);
out.println(y);
输出结果为：Null
            Null
