JMS入门的中的JNDI问题

[wnba1983]

我在网上找了个代码，导入到Eclipse后没有语法错误，代码如下

我不知道这个要怎么玩，可能要弄一个什么JNDI的配置，不过我没玩过，哪位大哥教教我啊！
我现在弄一个SAP的系统接口，它搞的很复杂，要涉及到很多东西，其中包括JMS消息机制，这块我没弄过，谁能教下我啊！

在代码根文件夹下即src下写一个jndi.properties
内容：
java.naming.provider.url = localhost:1099

java.naming.factory.initial = org.jnp.interfaces.NamingContextFactory

这个localhost后面的端口是什么意思啊，我是不是还需要tomcat之类的中间件什么环境啊，我现在什么都没做，就直接在Eclipse里面建了个工程，导了这2个java文件，要怎么运行啊！

[AspireHouse]

先运行SimpleQueueSender.java吧，它是发送者
再运行SimpleQueueReceive.java，它是接受者
不过直接Copy过来想一下运行正确不容易啊

[zl3450341]

SimpleQueueSender.java
SimpleQueueReceive.java

你看这英语单词也知道啊
一个发送 一个接收

我还是运行sender的时候就报异常了
就是这句话出错
queueConnectionFactory = (QueueConnectionFactory)
jndiContext.lookup(”QueueConnectionFactory”);

[AspireHouse]

报的是Not bound?异常

[sebatinsky]

建议楼主去网上搜搜JMS可运行程序和流程，其实就是数据源配置

[AspireHouse]

恩，去把EJB的JNDI和JMS以及MDB都看看

。。报什么异常呢 jar包没导入？

导入了，异常报错
Could not create JNDI context: javax.naming.NoInitialContextException:Cannot instantiate class......

[wnba1983]

说没法实例化一个Factory

[tmaclc]

JMS 是需要导入相应的jar包才能运行的，你要用人家的src，当然要先导入啦，你可以找一个JMS入门的例子看看，直接在CSDN的博客里搜就可以找到了啊

[crazylaa]

baidu+google,找些入门的资料看看。

JMS是需要有相应的容器的进行消息的处理的,需要有个服务器的,初始化InitialContext的时候要指向JMS服务器的地址,这两个类里并没有相应的内容,当然报错,先看一下JMS入门教程较好

你能给我个例子么，给个地址

我现在就是不知道怎么配置数据源，还有，怎么把它发布到tomcat里面去
