测试程序：
package chapter2;import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;public class FileTest { /**
 * @param args
 * @throws NamingException 
 */
public static void main(String[] args) throws NamingException {
// TODO Auto-generated method stub
Context ctx=new InitialContext();
FileListRemote dirs=(FileListRemote) ctx.lookup("FileList/remote");
String list=dirs.list("C:");
System.out.println(list);
}}
