我的EJB在运行时报如下错误，请各位高手帮忙看看！

[yohar]

是jb8+weblogic做的，是在查找home接口是报的错
Context ctx = new InitialContext();
home = (OrderViewHome) ctx.lookup("java:comp/env/ejb/local/OrderViewMain");

但我不知如何解决。

你好，你可以说得详细写吗？我对jbuider还不是太熟

[yohar]

谢谢各位，我的问题已经得到解决了
散分

[zosatapo]

你根本没有deploy　EJB成功

[ldh_0421]

部署出错！看看你部署时有没有报错！错误是什么！

[yohar]

我部署成功了，我是用jbuilder部署的，当时没有报错
Context ctx = new InitialContext();
home = (OrderViewHome) ctx.lookup("java:comp/env/ejb/local/OrderViewMain");
我把第二行语句中的"java:comp/env/ejb/local/OrderViewMain"换成class的路径就没错，如换成"ims.OrderViewHome"

[yohar]

难道没有人知道吗？请大家帮帮我

[hesi726]

我想你应该使没有在 Context ctx = new InitialContext();
home = (OrderViewHome) ctx.lookup("java:comp/env/ejb/local/OrderViewMain");
所处的 EJB 中添加对 OrderViewMain 对象的引用!!

使用 ,JBUILDER,在 EJB对象的设计下,有这个功能!!
这个功能的目的是使得 即使 其他EJB对象改变,例如, 别人的 ims.OrderViewHome
改成了 imms.OrderViewHome,你也不需要改变你的EJB对象的代码,而只要改变 部署文件即可!
