Hi, i am receiving following message in testlink log file while trying to integrate jira with testlink.

No connection could be made because the target machine actively refused it....Connect to Bug Tracker database fails:..

The jira(bug management link) is not displayed in the Testlink failed test case.

Installed wamp server and testlink in one machine and mysql 5.1 and jira in another machine.
In jira.cfg file 'BUG_TRACK_DB_HOST' is set to the IP address in which Mysql is present.

any clue on how to solve?
