JMS - 即使与远程提供程序的连接正常，也无法创建会话工厂

Question

I make a jar to connect to JMS provider, it's work fine in a server (a) but doesn't work on a server (b).

I verify that connection to the JMS provider from server (b) is OK via telnet as shown below:

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

The logs and exception that it's throw is below :

2018/08/01 11:19:47:921 - Processing command line arguments...
2018/08/01 11:19:47:927 - Preparing the output...  Writing to file = true

I don't how to debug such a problem knowing i'm new in JMS, i'll be grateful for any remarks and ideas..

Did you ever find out why this was happening? I have a related issue where an active JMS connection suddenly disconnects and the system starts throwing this exception until a system restart is done and then it connects again without fail.
