如何在JBoss 下部署EJB?

我是一个EJB初学者,在部署EJB时碰到了好多麻烦。
在Sun application server上失败了,因为部署工具总说我的ear是坏的!
在jboss下也不行,在我的servlet/jsp中找不到我指定的JNDI名字。
我用的是examples\org\jboss\docs\interest这个例子,
源代码丁点儿没动,因为它的build.xml有些问题,主要是路径,稍微改了一下,附在最后。
另外,部署一个ear,war 或者ejb jar的时候,只要copy到%jboss_dist%/server/default/deploy下就可以了么?
不用restart jboss?
我的系统是WinXP professional sp1, j2ee 1.4 beta 2, jboss-4.0.0DR2,我也不太清楚JBOSS的版本区别,
只是挑了个最新的down了下来 ^^
用modem down的,好辛苦,就看在我这份执著上,请大家不吝赐教吧!真的,我都快抓墙了!
