Hi,
does this recommendation also apply to Java JMS client? I have a connection
open all the time and create session, send message, close session for each
message to be sent. It works fine but after sending several thousands messages
I got very strange error:
javax.jms.IllegalStateException: Object AMQConnection:
Host: prgesbclu
Port: 5672
Virtual Host: test
Client ID: clientid
Active session count: 0 has been closed
