Question

我尝试使用命令提示符在Windows8系统上安装opensource软件。我之前从未做过类似的事情，而且我使用RMI的经验也不是很丰富。我需要一些帮助来解决我得到的异常错误。这是我遵循的程序：

我已经像这样设置了一个CLASSPATH

  set CLASSPATH=C:\kuwaiba7\service\lib\PersistenceAbstractionAPI.jar;C:\kuwaiba7\service\lib\PersistenceServiceRemoteInterfaces.jar

然后我启动RMI注册表：

  start "C:\Program Files\Java\jdk1.7.0_71\bin\rmiregistry.exe

将打开一个新的命令提示符窗口。在此窗口中，我为PersistenceService运行以下命令：

  C:\kuwaiba7\service>java -Djava.rmi.server.codebase="file:/C:/kuwaiba7/service/l
ib/PersistenceAbstractionAPI.jar file:/C:/kuwaiba7/service/lib/PersistenceServiceRemoteInterfaces.jar" -jar PersistenceService.jar

第一行显示已建立与数据库的连接，但后来出现了：java.rmi.ConnectException错误。

我的问题是： 1）如何确定RMI正确运行？ 2）我得到的这个异常是否意味着我的RMI没有运行？ 3）如何在命令提示符中解决此异常错误？

我还想提一下，在设置类路径之前我遇到了另一个错误： java.rmi.serverException java.rmi.unmarshalException 抛出java.lang.ClassNotFoundException

设置类路径后，我停止了这些错误。

我会对此提出任何帮助。正如我所提到的，我在使用RMI方面经验不足，请耐心等待！：）

我正在启动，然后使用为注册表打开的命令提示符窗口停止注册表。 EJP在上面的评论中非常清楚地解释了这一点。感谢。
