下面是各xml配置:

1.EJB中ejb-jar.xml:
 <ejb-jar>
     <description>HelloWorld Application</description>
     <display-name>HelloEJB</display-name>
     <enterprise-beans>
       <session>
         <ejb-name>HelloEJB</ejb-name>
         <home>mypack.HelloEJBHome</home>
         <remote>mypack.HelloEJBRemote</remote>
         <ejb-class>mypack.HelloEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Bean</transaction-type>
       </session>
     </enterprise-beans>
</ejb-jar>

2.EJB中jboss.xml:

 <jboss>
  <enterprise-beans>
    <session>
      <ejb-name>HelloEJB</ejb-name>
      <jndi-name>jndi_HelloEJB</jndi-name>
    </session>
  </enterprise-beans>
</jboss>

3.Web中jboss-web.xml:

 <jboss-web>
    <ejb-ref>
        <ejb-ref-name>HelloEJB</ejb-ref-name>
        <jndi-name>jndi_HelloEJB</jndi-name>
    </ejb-ref>
</jboss-web>

4.Web中web.xml:
   <ejb-ref>
        <ejb-ref-name>HelloEJB</ejb-ref-name>
        <ejb-ref-type>Session</ejb-ref-type>
     <home>mypack.HelloEJBHome</home>
     <remote>mypack.HelloEJBRemote</remote>
    </ejb-ref>

5.jsp页面:

    InitialContext ic = new InitialContext();
    Object o = ic.lookup(“java:comp/env/HelloEJB”);

就报第2句话报 jndi_HelloEJB not bound……….
