当应用程序名称包含句点时出现 NameNotFoundException
我有一个简单的 EJB 应用程序，大约 6 个月前可以运行。当我遇到这个问题时，我安装了最新的 JDeveloper (11.1.1.3.0)，并试图让它再次工作。
部署在这一行失败：
TeacherManager teacherManager = (TeacherManager)context.lookup("Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager");
带有消息（由我强调）：
javax.naming.NameNotFoundException：尝试查找“Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager”时未找到子上下文“Uran_2”。已解决 '' [根异常是 javax.naming.NameNotFoundException：尝试查找 'Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager' 时未找到子上下文 'Uran_2'。已解决'']； 剩余名称“Uran_2/0-TeacherManager#hu/elte/pgy2/BACNAAI/UranEJB/TeacherManager”
显然应用程序的名称（Uran_2.0）以某种方式提示 JDeveloper（或 JNDI？我不确定）将名称中的 . 替换为 /，这显然会导致 JNDI 查找失败。我该如何解决这个问题？
I have a simple EJB app that used to work about 6 months ago. I installed the latest JDeveloper (11.1.1.3.0) and I'm trying to get it to work again, when I ran into this problem.
Deployment fails on this line:
TeacherManager teacherManager = (TeacherManager)context.lookup("Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager");
With the message (emphasis by me):
javax.naming.NameNotFoundException: While trying to lookup 'Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager' didn't find subcontext 'Uran_2'. Resolved '' [Root exception is javax.naming.NameNotFoundException: While trying to lookup 'Uran_2.0-TeacherManager#hu.elte.pgy2.BACNAAI.UranEJB.TeacherManager' didn't find subcontext 'Uran_2'. Resolved '']; remaining name 'Uran_2/0-TeacherManager#hu/elte/pgy2/BACNAAI/UranEJB/TeacherManager'
Apparently the application's name (Uran_2.0) somehow prompts JDeveloper (or JNDI? I'm not sure) to replace the . in the name with a /, which obviously causes the JNDI lookups to fail. How can I get around this?

您的无状态/有状态 EJB 应显式指定 JNDI 名称：
@Stateless(mappedName = ?)如果这不起作用，您可以使用
context.list("")浏览 jndi 树以查看部署了哪些远程 EJB。Your Stateless/Stateful EJB should explicitly specified the JNDI name :
@Stateless(mappedName = ?)If this doesn't work, you can use
context.list("")to browse the jndi tree in order to see what remote EJB are deployed.
