怎么解决？

[provider]

这是运行时的错误？还是发布时的？

第一，JNDI名称不符，注意大小写。
第二，EJB部属的服务器没启动或EJB部属有问题，一般启动服务器后到控制台可以调整。
第三，Context获取不正确，就是那个查找JNDI名字的东东。
最好你把代码贴上来。

这是测试ejb的时候报的错误,部署是正确的,我也认为是lookup("..."),有点问题,就是不知道怎么解决.

如果是lookup错误该怎么解决呢?
谢谢各位,有奖.

在不断总结下,问题得以解决,原来是粗心将jboss.xml写错了,所以lookup不能找到home接口,现在得以运行了,谢谢各位的解答.
