此时报错Qjava.rmi.ConnectException: Connection refused to host: 192.168.23.X?br /> RMI的调用原理基本如下: 大致译如下Q首先客L必须通过Naming.lookup得到服务端服务的一个指针或者叫指针Q一旦拥有的q个应用Q客L用服务的引用里面包含的主机名(ip)和端口来讉K服务?br /> 也就是说Q虽然我们就服务端的IP和端口去Naming.lookup("http://10.10.116.XX:8808/SAMPLE-SERVER");Q但是服务端q回的服务的引用里面包含的ipq不是lookup时的ip?br />官方说法Q?br />【In many versions of the JDK (all versions of the JDK except in v1.1 and the latest releases), Java RMI may default to using an unresolvable server hostname (for example: unqualified names, Windows Internet Naming Service (WINS) names, or unqualified DHCP names). When a Java RMI client invokes a remote method using a reference that contains an unresolvable server hostname, the client will throw an UnknownHostException.?/span>
In order to generate functional remote references, Java RMI servers must be able to supply a fully qualified hostname or IP address that is resolvable from all Java RMI clients (an example of a fully qualified hostname is foo.bar.com). If a Java RMI program provides a remote callback operation, then that program serves a Java RMI object and consequently, must be able to determine a resolvable hostname to use as its server hostname in the remote references it passes to Java RMI clients. VMs that make calls to applets that serve remote objects may throwUnknownHostExceptions because the applet has failed to provide a usable server hostname.
If your Java RMI application throws an UnknownHostException, you can look at the resulting stack trace to see if the hostname that the client is using to contact its remote server is incorrect or not fully qualified.?nbsp;If necessary, you can set the java.rmi.server.hostname property on the server to the correct IP address or hostname of the server machine and Java RMI will use this property's value to generate remote references to the server.?/strong>

一个报错例子如下:

相应的英文如下:
Cause: An extent could not be allocated for a table segment in tablespace

请大家关注红色部分: <!-- Make the Spring object factory the automatic default -->意思是Q会Spring object factory 讄为默认。也是说我们不配置struts.objectFactory=spring 但是只要q个包在classpath下就{于讄了struts.objectFactory=spring ?br />
