求助：rmi.UnmarshalException:error unmarshalling return;

[歆鸿]

这是错误：
java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: ManagementSystem.ManagementSystem (no security manager: RMI class loader disabled)

这是代码部分：
public class MSserver {
public static void main(String[] args) {
try {
LocateRegistry.createRegistry(1099);
ManagementSystem MS=new ManagementSystemImpl();
Naming.rebind("rmi://localhost:1099/ManagementSystem",MS);
System.out.println("MSserver start!");
} catch (Exception e) {
e.printStackTrace();
}

}
}



public class TestClient {
public static void main(String[] args) {
try {
ManagementSystem MS=(ManagementSystem) Naming.lookup("rmi://localhost/ManagementSystem");
GroupPurchaseManagementSystem GPMS=MS.getMS();
} catch (Exception e) {
e.printStackTrace();
}
}
}


谁懂得帮个忙，很着急的。。。。
