Question

我正在使用有状态会话bean来创建购物篮。我无法访问我的bean并收到以下错误

ERROR BasketBean#ejb.remote.BasketBeanRemote -- service jboss.naming.context.java."BasketBean#ejb.remote.BasketBeanRemote"javax.naming.NameNotFoundException: BasketBean#ejb.remote.BasketBeanRemote -- service jboss.naming.context.java."BasketBean#ejb.remote.BasketBeanRemote"

我认为问题出在我的查询中

final InitialContext context = new InitialContext();
BasketBeanRemote basket = (BasketBeanRemote)context.lookup("BasketBean#ejb.remote.BasketBeanRemote");

我不确定将什么放入查找字符串

我的BasketBeanRemote位于名为ejb.remote的软件包中，而我的BasketBean位于我的ejb项目中的ejb.beans

查找应该怎么做？我正在从我的战争项目中访问它。

Answer 1

final InitialContext context = new InitialContext();
BasketBeanRemote basket = (BasketBeanRemote)context.lookup("YOUR_PROJECT_NAME/BasketBean/remote");

Answer 2

我似乎找到了this post

的答案

我在servlet上需要@EJB注释：

@EJB(name="BasketBeanRemote", beanInterface = Bean.class)
private BasketBeanRemote basketBean;

然后使用@EJB注释绑定的名称在服务方法中进行查找：

BasketBeanRemote basket = (BasketBeanRemote) new InitialContext().lookup("java:comp/env/BasketBeanRemote");

EJB访问有状态会话Bean NameNotFoundException
