The Hansoft JIRA integration initiates communication with the JIRA server by contacting the servlet HansoftService module added by installing the Hansoft Support JIRA version 2 plugin. The hostname of the JIRA integration server and the number of an unused port on that server is sent to the servlet. The hostname and port are configured in the JiraIntegrationSettings file as "NotificationHost" and "NotifcationPort". The servlet opens a TCP channel back to the JIRA integration server. This channel is then used for all communication between the integration and the JIRA server.
