所以我已經閱讀了類似的問題，但我還沒有找到任何我完全理解的東西。Java.rmi.ConnectException：連接拒絕主機：localhost
http://www.coderanch.com/t/487650/java/java/java-rmi-ConnectException-Connection-refused
http://protegewiki.stanford.edu/wiki/Troubleshooting_Client_Server_Connections
http://docs.oracle.com/javase/7/docs/technotes/guides/rmi/faq.html#domain
我有它每隔幾天崩潰的服務器，我試圖找出問題所在。該軟件運行在客戶提供的環境中，我需要知道我們是否是問題或Windows /網絡。
我的問題是... RMI註冊表，是java創建的東西還是它存在於Windows中的東西？爲什麼到localhost的連接會突然變得不可用或被拒絕？有什麼我可以做的立即排除故障？
的RMI配置是在這裏：
<RMIService>
<class>com.s.i.system.RMIService</class>
<server name="Server">
<host>localhost</host>
<timeout>0</timeout>
</server>
</RMIService>
這裏是在日誌中創建錯誤。
