关于一个CORBA方面的问题。

package MyServer.hello;import java.util.Properties;
import org.omg.CORBA.ORB;
import org.omg.CosNaming.NamingContextExt;
import org.omg.CosNaming.NamingContextExtHelper;
import org.omg.PortableServer.POA;
import org.omg.PortableServer.POAHelper;public class Server {
public static void main(String[] args) {
// 初始化ORB
Properties prop =new Properties();
prop.put("org.omg.CORBA.ORBInitialPort","1050");
prop.put("org.omg.CORBA.ORBInitialHost","192.168.100.102");
ORB orb = ORB.init(args,prop);
System.out.println("Server ORB init successfully!");
try {
// 初始化POA
POA poa = POAHelper.narrow(orb
.resolve_initial_references("RootPOA"));
poa.the_POAManager().activate();
//创建BookImp
BookImp bookimp =new BookImp();
//获得BookImp的引用
org.omg.CORBA.Object object =poa.servant_to_reference(bookimp);
//使用 naming service  
 NamingContextExt nc = NamingContextExtHelper.narrow(orb  
     .resolve_initial_references("NameService"));
//绑定对象
 nc.bind(nc.to_name("hello.BookImp"), object); 
 orb.run(); } catch (Exception ex) {
ex.printStackTrace();
}
}
}这是CORBA的一个服和端，是在ECLIPSE中开发的，在运行的时候，却报如下错误，请高手们帮忙看一下：Server ORB init successfully!
