2、你的jndi怎么配置的？
3、你发布后jboss状态正确吗4、建议使用servlet测试

非常感谢！
jndi需要配置吗？怎么配置？配置哪个文件？或其它！
Initializing bean access.
初始化的时候就出错了，可能是EJB容器的问题吧。容器启动后在，jb8左边的项目列表中找到XXXX.jar，右键部署，成功部署后再run client
一切OK
Object ref = context.lookup("FirSes");
//look up jndi name and cast to Home interface
firSesHome = (FirSesHome) PortableRemoteObject.narrow(ref, FirSesHome.class);用servlet测试，输出
FirSes not bound初步确定是jndi问题，Home JNDI name 设置为:FirSes
内容
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost这些是要根据具体的容器来改的
要在你class路径里
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces这个jndi.properties文件在jboss中client目录下的jbossjmx-ant.jar文件里，通常jboss的缺省端口号是1099，所以必须在jndi.properties里将java.naming.provider.url配置成和你访问的jboss服务匹配的url。如果觉得改jndi.properties不方便的话，建议在你的client程序里的initialize()函数中的 Object ref = context.lookup("FirSes"); 语句之前加上如下代码：
System.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url", "localhost:1099");
-Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory -Djava.naming.provider.url=localhost:1099 -Djava.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
没有设置Application parameters我测试了，按你们的方法，出现的错误一样！
太打击学习积极性了！！！我坚持！

很显然是你环境的问题...估计你的jndi还是没搞定..如果可以的话,你可以手动在控制台下进行编译,打包,发布,然后运行test..
这样你或许更清楚你哪些包或环境不对.

我已经看了，thanks为什么看不到1099是激活的？JNDI还能用吗？
我有点不好意思说，是我的jboss没启动。我一直以为直接点击client->右键->run using "client"，
jboss就会在JB8里启动运行，其它相关的服务也会启动，现在
发现我错了。还好发现JNDI服务没启动，同时shaomickey(不够刺激)
提醒了我 ，在此非常感谢。
也可以在jbuilder中运行jboss啊，上次给你的网址里说得很详细，自己看一看吧！！！！
http://mattkelli.com/tech/jboss/jbuilder7/老大，我是这个论坛的新手，今天忙了一上午了，头昏眼花，有么有给分啊？？！！！
呵呵～～～～～！！！
