Subject Re: How know when "Session is closed" after establish connections between uima-as client and ActiveMQ?
Date Wed, 05 Jul 2017 18:10:41 GMT
Here the stack trace for the error that asked me:
jul 05, 2017 2:08:50 PM
org.apache.uima.adapter.jms.client.ActiveMQMessageSender run
ADVERTENCIA:
javax.jms.IllegalStateException: The Session is closed
	at org.apache.activemq.ActiveMQSession.checkClosed(ActiveMQSession.java:771)
