SPRING 调用远程接口出错

[litao315367624]

EJB项目中的接口和实现类
package dao;



import javax.ejb.Remote;



import Entity.Person;

import Entity.StudentClass;



@Remote

public interface PersonDaoRemote {



public void save(Person p);



public void saveStudent(StudentClass sc);



}

package dao;



import javax.ejb.Stateless;

import javax.persistence.EntityManager;

import javax.persistence.PersistenceContext;



import Entity.Person;

import Entity.Student;

import Entity.StudentClass;




－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
@Stateless

public class PersonDao implements PersonDaoRemote {

@PersistenceContext(name="pu")

EntityManager em;



public void save(Person p) {

em.persist(p);

}



public void saveStudent(StudentClass sc){

em.persist(sc);

}

}



-----------------------------------------------------------------------------------------
客户端项目中的配置
applicationContext.xml

<bean id="persondao" class="org.springframework.ejb.access.SimpleRemoteStatelessSessionProxyFactoryBean" lazy-init="true">

<property name="jndiName" value="PersonDao/remote"></property>

<property name="businessInterface" value="dao.PersonDaoRemote"></property>

<property name="jndiEnvironment">

<map>

<entry key="java.naming.factory.initial" value="org.jnp.interfaces.NamingContextFactory"></entry>

<entry key="java.naming.provider.url" value="jnp://localhost"></entry>

</map>

</property>

</bean>



<bean id="remotePer" class="Servlets.RemotePer">

<property name="persondao">

<ref bean="persondao"/>

</property>

</bean>
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
persondao 作为remotePer的一个属性，通过spring 注入
test.java中测试的时候发生了错误


错误信息如下

Exception in thread "main" org.springframework.remoting.RemoteLookupFailureException: EJB instance [jboss.j2ee:jar=EJBJPA.jar,name=PersonDao,service=EJB3] is not a Remote Stateless Session Bean

请高手指点一下阿！！！ 急急急。
