为什么文件上传不了啊？？？

来源：互联网发布：cpa软件服务编辑：程序博客网时间：2024/04/27 14:51

我自己本机上传文件是ok的

别人访问http://172.25.49.35:8080/servlet/login可以正常获得网页
上传文件后也没有报错，就是上传不了

代码如下

login.html是放在apache servlet目录下的

<html>
<head>
<title align="center">Welcome to the Share PPT Home ! </title>
</head>
<body>
<h3 align="center">welcome to the share PPT Center</h3>
<form action = "http://172.25.49.35:8080/servlet/login"
method="get">
<div align="center">
上传者 ID
<input type="text" name="OwnerID" size ="9"/>
<br>

作者Author
<input type="text" name="Author" size ="9"/>
<br>

Permission
<input type ="radio" name="Permission" value="0" checked/>共享
<input type="radio" name="Permission" value="1"/>仅好友可见
<input type="radio" name="Permission" value="2"/>仅自己可见
<br>

选择要上载的文件
<input type="file" name="filename" >
<br>
<input type="submit" value="上载" >
</div>

</form>
</body>
</html>

while((r=input.read())!=-1)
{
//out.write((byte)r);
tofile.write((byte)(r));
}
input.close();
//out.close();
tofile.close();

} catch (FileNotFoundException e) {

}

为什么别人的文件上载不了呢，是我这边访问不到他们的文件吗？
求高人指点啊~~~
本人刚刚开始自学网页制作，是想做一个ppt在线共享网站，可是现在连文件都上传不了，急啊~~~~

另外谁可以讲讲jsp是什么啊？java+apache就是jsp了吗？

求教~~~
