EJB 类的代码

  package Beans;

  import java.rmi.RemoteException;

  import javax.ejb.SessionBean;

  import javx.ejb.SessionContext;

  public class AddBean Implements SessionBean

  {

    //some method declare

  }

147 、如何校验数字型 ? var re=/^d{1,8}$|.d{1,2}$/;

var str=document.form1.all(i).value;

var r=str.match(re);

if (r==null)

{

   sign=-4;

   break;

}

else{

   document.form1.all(i).value=parseFloat(str);

}

148 、 将一个键盘输入的数字转化成中文输出

(例如:输入:1234567     输出:一百二拾三万四千五百六拾七)

用java语言实现,,请编一段程序实现!
