在哪設EJB的JNDI的名字?

Question

這是ejb-jar.xml中的片段:
<session>
      <description>Session Bean ( Stateless )</description>
      <display-name>UserSession</display-name>
      <ejb-name>UserSession</ejb-name>
      <home>com.fiti.ejb.UserSessionHome</home>
      <remote>com.fiti.ejb.UserSession</remote>
      <local-home>com.fiti.ejb.UserSessionLocalHome</local-home>
      <local>com.fiti.ejb.UserSessionLocal</local>
      <ejb-class>com.fiti.ejb.UserSessionBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
      <ejb-ref>
        <ejb-ref-name>ejb/Userentity</ejb-ref-name>
        <ejb-ref-type>Entity</ejb-ref-type>
        <home>com.fiti.ejb.UserentityHome</home>
        <remote>com.fiti.ejb.Userentity</remote>
        <ejb-link>Userentity</ejb-link>
      </ejb-ref>
    </session>哪個是設定jndi的屬性?
怎麼呼叫啊?lookup("java:comp/env/ejb/UserSessionBean");

Answer 1

首先应该选个运行环境把，
用weblogic的话，jndi名字是在weblogic-ejb-jar.xml中的，不在ejb-jar.xml

Answer 2

是的，与具体的产品有关系。
一般在****-ejb-jar.xml中。

Answer 3

lookup("java:comp/env/ejb/UserSessionBean");
java:comp/env/這一句是身麼意思?

Answer 4

用的什么开发工具？在JBuilder中有图形化界面可以设定。
客户端通过这个JNDI名查找Home接口

Answer 5

lookup("java:comp/env/ejb/UserSessionBean");
java:comp/env/這一句是身麼意思?
----------------------------------------------这应该是书上的例程，被楼主一并抄了上来

我这边有jboss配置,打包到ejb中
jboss.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.0//EN" 
"http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">
<jboss>
<enterprise-beans>
<!--
       To add beans that you have deployment descriptor info for, add
       a file to your XDoclet merge directory called jboss-beans.xml that contains
       the <session></session>, <entity></entity> and <message-driven></message-driven>
       up for those beans.
     -->
<entity>
<ejb-name>Product</ejb-name>
<jndi-name>ProductBean</jndi-name>
<local-jndi-name>ProductLocal</local-jndi-name>
</entity>
</enterprise-beans>
<resource-managers>
</resource-managers>
</jboss>

Answer 7

用weblogic的话，jndi名字是在config.xml中

Answer 8

假設JNDI的名字是ProductBean 那麼呼叫的時候就應該是:lookup("ProductBean")?
  還是lookup("ejb/ProductBean")?

Answer 9

還有JNDI location 是做身麼的?
