WSO2 ESB (4.9.0) / MB (3.1.0) - Could not connect to broker (Connection refused)

Question

I have WSO2 ESB (4.9.0) and WS02 MB (3.1.0) installed on a mounted drive on a server running Ubuntu 16.04.5 LTS.

The ESB has API endpoints configured that of which push received data to the message broker upon a post request. This process was working flawlessly until I updated the server via the typical update commands ie sudo apt-get update , sudo apt-get upgrade , sudo apt-get dist-upgrade followed by a system reboot.

Upon rebooting and starting the MB followed by the ESB (both manually via sh wso2server.sh ), I receive the following error from the ESB:

ERROR - JMSConnectionFactory JMS Exception while creating connection through factory 'QueueConnectionFactory' Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused (Connection refused)

WARN - JMSPollingConsumer Inbound JMS endpoint unable to get a connection.

This obviously prevents the ESB sending messages to the MB. What could be causing this?

On a side note, attempting the same process via a non-root account results in the following error:

Error: JAVA_HOME is not defined correctly. CARBON cannot execute java

Answer 1

The following error occurred due to your inbound endpoint trying to connect to the ActiveMQ. The default port of the ActiveMQ is 61616.

[2019-02-06 14:06:57,206] ERROR - JMSConnectionFactory JMS Exception while creating connection through factory 'QueueConnectionFactory' Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused (Connection refused) 
[2019-02-06 14:06:57,207] WARN - JMSPollingConsumer Inbound JMS endpoint unable to get a connection.

I am not sure how it got changed after server updates. Anyway, you should be able to change the inbound endpoint configuration to work with the WSO2 MB 3.1.0 going through the following documentation [1].

The following error coming because of root doesn't have access to the JAVA_HOME. I mean the environment variable you have set as JAVA_HOME is not visible to the root user.

Error: JAVA_HOME is not defined correctly. CARBON cannot execute java

Hope above information will help to resolve the issue.
