一个RMI程序老出来NoClassDefFoundError错误

net/jini/admin/Administrable，检查这个类所在的包是否在编辑环境中有？？

  1.   

    net/jini/admin/Administrable这个接口在jini-ext.jar中，我运行和编译的时候都指明了jini-ext.jar。
    E:\Projects\eclipse\workspace\TestRMI>javac -classpath d:\jini2_1\lib\jini-core.jar;d:\jini2_1\lib\jini-ext.jar;d:\jini2_1\lib\sun-util.jar test\*.javaE:\Projects\eclipse\workspace\TestRMI>rmic -classpath d:\jini2_1\lib\jini-core.jar;d:\jini2_1\lib\jini-ext.jar;d:\jini2_1\lib\sun-util.jar;.\ test.BackendE:\Projects\eclipse\workspace\TestRMI>java -cp d:\jini2_1\lib\jini-core.jar;d:\jini2_1\lib\jini-ext.jar;d:\jini2_1\lib\sun-util.jar;.\ -Djava.rmi.server.codebase=file:/e:\Projects\eclipse\workspace\TestRMI/ -Djava.security.policy=java.policy test.Server

    Client端找不到Impl类的stub文件，所以会报错的，你把服务器上的stub类copy到Client下面再试试
