java.net.SocketException：來自服務器的文件意外結束

我正在使用一個servlet，它將字符串參數傳遞給另一個遠程系統中的另一個Servlet，以從該遠程servlet獲取xml響應。java.net.SocketException：來自服務器的文件意外結束

這工作正常，當我試圖從我的本地PC連接到遠程Servlet。

但是，當我從另一臺服務器執行相同的操作時，出現錯誤java.net.SocketException: Unexpected end of file from server。

錯誤：

代碼在我的servlet（客戶端）：

if(queryString.equals("Inventory")) { 

    String partNum = (String)session.getAttribute("PARTNUM"); 
    String locId = (String)session.getAttribute("locids"); 

    strURL = strURL+"/InventoryStatus?queryStr=Inventory&PARTNUM="+partNum; 

    URLConnection dbGatewayURL = new URL(strURL).openConnection(); 

    BufferedReader in = new BufferedReader(new InputStreamReader(dbGatewayURL.getInputStream()));//--This is line 52 Mentioned in Error above 

    StringBuffer responseData = new StringBuffer(); 
    String line=""; 

    while((line = in.readLine()) != null) { 
     responseData.append(line); 
    } 

    String result =responseData.toString(); 
    request.setAttribute("inventryStock",result); 

    RequestDispatcher rd=request.getRequestDispatcher ("inventryStatus.jsp?resp=Yes"); 
    rd.forward(request, response); 
}

代碼沒什麼問題，但事情是遠程服務器沒有聽我的服務器連接，因此我嘗試了相同的代碼，但在另一臺遠程服務器上，這次它的工作正常... 。！任何機構知道原因............？

謝謝，需要將我的服務器添加到受信任的主機。雖然它是基於SOAP的調用，但由於我的服務器不在受信任的主機中，因此我得到了類似的跟蹤 – cpandey05 2016-12-14 11:24:20

嘗試等待（）後立即的URLConnection dbGatewayURL =新的URL（strURL）.openConnection（）;

有可能程序移動到下一行之前，它能夠使連接

好，沒有運氣..做出下面的變化，並得到了另一個例外： – Warrior 2011-06-04 09:55:25

嘗試遠程登錄到您的服務器的遠程servlet和看它是否連接正常。如果不是，那麼這是一個連接問題。

如果有，請嘗試使用TCP監視器來查看從您的服務器到具有該servlet的遠程服務器的HTTP流量。 http://ws.apache.org/commons/tcpmon/
