ObjectInputStream中的EOFException僅在Webstart不是由java（w）.exe發生？

Question

與啓動應用程序相比，熟悉Webstart（javaws.exe）開始差異的任何人。使用java.exe或javaw.exe關於流？

這是使用Webstart的時我只得到異常：

java.io.EOFException 
    at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source) 
    at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source) 
    at java.io.ObjectInputStream.readStreamHeader(Unknown Source) 
    at java.io.ObjectInputStream.<init>(Unknown Source) 
    at fasttools.jtools.dss.api.core.remoting.thinclient.RemoteSocketChannel.<init>(RemoteSocketChannel.java:77) 

我就是這樣設置在兩側的連接

//==Server side== 
//Thread{ 
Socket mClientSocket = cServSock.accept(); 
new DssServant(mClientSocket).start(); 
//} 

DssServant(Socket socket) throws DssException { 
    try { 
    OutputStream mOutputStream = new BufferedOutputStream(socket.getOutputStream()); 
    cObjectOutputStream = new ObjectOutputStream(mOutputStream); 
    cObjectOutputStream.flush(); //publish streamHeader 
    InputStream mInputStream = new BufferedInputStream(socket.getInputStream()); 
    cObjectInputStream = new ObjectInputStream(mInputStream); 
    .. 
    } catch (IOException e) { 
    .. 
    } 
    .. 
} 

//==Client side== 
public RemoteSocketChannel(String host, int port, IEventDispatcher eventSubscriptionHandler) throws DssException { 
    cHost = host; 
    port = (port == 0 ? DssServer.PORT : port); 
    try { 
    cSocket = new Socket(cHost, port); 

    OutputStream mOutputStream = new BufferedOutputStream(cSocket.getOutputStream()); 
    cObjectOut = new ObjectOutputStream(mOutputStream); 
    cObjectOut.flush(); //publish streamHeader 
    InputStream mInputStream = new BufferedInputStream(cSocket.getInputStream()); 
    cObjectIn = new ObjectInputStream(mInputStream); 

    } catch (IOException e) { 
    .. 
    } 
    .. 
} 

[編輯] Webstart的控制檯說： Java Web Start 1.6.0_19 使用JRE版本1.6.0_19-b04 Java HotSpot（TM）客戶端VM

服務器運行同樣1.6u19

Answer 1

oH mY !!

我找到了問題所在。 由從現有程序複製的servlet生成的JNLP文件，提供了port-nr參數。但端口號沒有更正.. 提供的端口是（現有）安全套接字..我的應用程序使用非安全套接字！

多麼awfull錯誤

Answer 2

我認爲你可能不得不請求在您的JNLP文件權限。嘗試添加

<security> 
    <all-permissions/> 
</security>
