Question

我制作了一个罐子以连接到JMS提供程序，它在服务器（a）上可以正常工作，但在服务器（b）上不能正常工作。

我确认通过telnet从服务器（b）到JMS提供程序的连接正常，如下所示：

    -> telnet -d 10.127.161.247 4447
Trying 10.127.161.247...
Connected to 10.127.161.247.

引发的日志和异常如下：

我不知道如何调试这样的问题，因为我是JMS的新手，对于任何评论和想法，我将不胜感激。

非常感谢

你有没有发现为什么会发生这种情况？我有一个相关的问题，一个活动的 JMS 连接突然断开，系统开始抛出这个异常，直到系统重新启动完成，然后它再次连接，没有失败。

JMS-即使可以连接到远程提供程序，也无法创建会话工厂
