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

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。稍后，我将得到如下异常：

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

然后，我将从glassfish服务器中删除ejb模块，并重新启动服务器。那就行了。那么，如何克服这个问题呢

尝试重新启动服务器。Weblogic 11g有此缺陷。

重启也有助于GlassFish（v3）。
