不好意思!看的头大想错了!
socket.close();方到jbInit();后看看不要方在receiveFiles()试一下

[shuai45]

这也太长了
看你的错误是java.net.SocketException: socket closed
看样子socket 已经关闭。

[njp20033266njp]

int num = fis.read(buf);
while ((num = fis.read(buffer)) != -1) {
os.write(buf, 0, num);
os.flush();
num = fis.read(buf);
}

这样改一下看看行不行

[杨武兵]

njp20033266njp()：
老兄：这样改不跟没改一样啊!

[杨武兵]

njp20033266njp()
非常谢谢你能够抽空看完我的那么代码。
我原本觉得自己发这么代码，肯定没人会去看的。
没抱什么希望。
不过，你真是给了我很大的惊喜啊。
再次感谢。
你给的建议，我也会认真考虑的。

[杨武兵]

njp20033266njp():
我认真看了你给的修改意见。
好象不行啊。
socket.close();方到jbInit();
那不是一创建对象就关闭了socket。
那还怎么传输文件啊。

[杨武兵]

好的！出现异常的代码是：
while(true)
{
in=0;
in = doc.read(buf);
if(in!=0)
break;
}
和：
if(new String(buf,0,counter).equalsIgnoreCase("yes"))
{
FileInputStream fis = new FileInputStream(file);
int num = fis.read(buf);
while (num != ( -1)) {
os.write(buf, 0, num);
os.flush();
num = fis.read(buf);
}
os.close();
fis.close();
//socket.close();
}
}

[杨武兵]

虽然
jButton2_actionPerformed
jButton3_actionPerformed
都会调用，
但是在同一时刻却只有一个方法会使用
方法receiveFiles()。

[njp20033266njp]

不是方到jbInit();里面
反正等你程序完成后你才能关闭socket.close();
因为receiveFiles()好向不是只一个在用
jButton2_actionPerformed
jButton3_actionPerformed
都调用了
要不你就要在receiveFiles()在打开一次
我能给的想法就这么多了
我水平不高希望有高手来帮忙

[andrew_fan]

看到头大。
帖关键代码

[njp20033266njp]

我感觉这样写没错
同一时刻却只有一个方法会使用
方法receiveFiles()。
你是指什么!也就是jButton2_actionPerformed或jButton3_actionPerformed在程序只可能走一下吗可是你
socket 是全居的变量一但关闭你会从新在做ConfirmFrame的构造吗?
