关于rmi的问题，搞了我3天了头都大死了实在没有办法了

楼主linseng129（IT届的菜鸟）2005-04-04 00:34:15 在 Java / J2EE / EJB / JMS 提问

我写了两个rmi的程序，问题都出在：HelloIn hi=(HelloIn)Naming.lookup("rmi://localhost:1099/hello");上，我改了很多方法但是都是没有用总是出下下面的信息：
java.rmi.ConnectException: Connection refused to host: localhost; nested exception is:
java.net.ConnectException: Connection refused: connect

麻烦了，请帮我个忙吧
还有我想请问下在jb9里面如果一切都弄好了那么在运行application时mainclass是不是设置为Clinet端的class?如果是那么服务器端的class不是要先运行吗怎么回事呢？问题点数：20、回复次数：18Top

第一个是后来我改了端口的出错信息Top

在wizards里选Extenal Build Task,建rmic的pre-compile命令；
然后在runtime configuration里对服务器端的class建rmic命令的config；
修改JB自带JDK里的java.policy文件：
添加grand{permission java.security.Allpermission;};；
在tool里点击RMIregistry启动注册表；
运行：
1--〉rmic的congfig
2-->客户端class的config

你的registry服务开了没啊
在命令行下输入start rmiregistry 1099启动1099端口Top

registry服务当然开了，我是在jb9中调试的，先在tools里面把rmiregistry打开，然后先在server端的，再开client端的对吗Top
