JSP如何与EJBSessionBean通讯

下面的代码段作了很好的示范

<%@ page import="javax.naming.*, javax.rmi.PortableRemoteObject,

foo.AccountHome, foo.Account" %

<%!

//定义一个对SessionBeanHome接口实例的全局引用

AccountHome accHome=null;

public void jspInit() {

//获得Home接口实例

InitialContext cntxt = new InitialContext( );

Object ref= cntxt.lookup("java:comp/env/ejb/AccountEJB");

accHome = (AccountHome)PortableRemoteObject.narrow(ref,AccountHome.class);

}

%

<%

//实例化SessionBean

Account acct = accHome.create();

//调用远程方法

acct.doWhatever(...);

// 如此等等

%
