javax.naming.NameAlreadyBoundException：在 glassfish 服务器 v2 中

Question

我正在使用 netbeans 在 glassfish 服务器中实现无状态会话 bean ejb3。第一次，它工作正常。后来，我收到如下异常：

LDR5012: Jndi name conflict found in
[SampleEjb3]. Jndi name
[Lulu.HellostatelessRemote] for bean
[HellostatelessBean] is already in
use. LDR5013: Naming exception while
creating EJB container:

然后，我将从 glassfish 服务器中删除 ejb 模块，然后重新启动服务器。然后它就会起作用。那么，如何克服这个问题..

Answer 1

尝试重新启动服务器。 Weblogic 11g有这个bug。
