SimpleDB的设置java.rmi.NotBoundException：SimpleDB的

我想SimpleDB的安装到我的computer.I已定义的CLASSPATH环境变量SimpleDB的设置java.rmi.NotBoundException：SimpleDB的

.;C:\SimpleDB

用户变量和系统变量CLASSPATH为

C:\Program Files\Java\jdk1.7.0_45\bin;C:\Program Files\Java\jdk1.7.0_45\jre\bin

和PATH与CLASSPATH相同。我打开命令提示符并进入SimpleDB。然后我键入start rmiregistry。打开另一个窗口。之后，我键入java simpledb.server.Startup studentdb。输出是：

new transaction: 1 
recovering existing database 
transaction 1 committed 
database server ready

之后，我去了SimpleDB的\ studentClient \的SimpleDB和类型的Java CreateStudentDB.And它给了我下面的错误。

C:\SimpleDB\studentClient\simpledb>java CreateStudentDB

我刚刚在创建数据库时键入“java simpledb.server.Startup studentdb”到“启动java simpledb.server.Startup studentdb”，打开了另一个窗口。然后我继续执行上一个窗口中的相同操作。它工作正常为了我。
