Tomcat服務器在美國運行。我使用Java的HTTPURLConnection連接到來自中國的服務器。請參閱下面的tomcat服務器端的客戶端使用的代碼片段和https連接器配置。無法偶爾上傳zip文件
<!-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->
<Connector acceptCount="100" clientAuth="false" connectionTimeout="-1" debug="4" disableUploadTimeout="true" enableLookups="false" keystoreFile="conf/server.keystore" keystorePass="passw47d" maxSpareThreads="75" maxThreads="150" minSpareThreads="25" port="443" scheme="https" secure="true" sslProtocol="TLS" useBodyEncodingForURI="true"/>
URL url=new URL(urlString);
HttpsURLConnection connection=null;
try
{
connection=(HttpsURLConnection)url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/zip");
connection.setRequestProperty("Transfer-Encoding", "chunked");
connection.setChunkedStreamingMode(4096);
connection.connect();
sout=new BufferedOutputStream(connection.getOutputStream());
break;
}
catch(FileNotFoundException exc)
{
throw exc;
}
bis=new FileInputStream(zipfile);
int i;
byte bytes[]=new byte[4096];
while((i=bis.read(bytes))!=-1)
{
sout.write(bytes,0,i);
sout.flush();
}
sout.close();
bis.close();
客戶端大多數時間成功上傳zip文件。客戶端程序偶爾會引發以下異常。

可能是什麼問題?
用於Apache HttpClient的+1。它內置了錯誤處理邏輯,只需重試大多數基本錯誤的請求,並允許您指定自己的邏輯。 – 2009-06-16 15:40:02
