About your questions - So, how do you mean the topic is an “incorrect path”? By default, you can publish to any topic you want to, unless you configure your ACL profile to disallow it. What is your ACL profile configuration?
As a producer, I am sending msg to the customer (will remove looping i.e just of my verification. our case is to send a single message only). The customer (target system) has provisioned the ACL profile configuration, but for one of the topics, they neglected to include the topic details in the ACL. When I publish a msg to this topic, no exception is raised, which led us to investigate the issue. We discovered that the exceptions are not being triggered and none of the methods in the implemented callback mechanism are executing.
Note: After correcting the ACL profile, we are able to send msgs without any issues. However, the methods in the implemented callback mechanism are still not executing. The only time a JCSMPExecption is raised is when there are issues related to the host, username or pwd.
