Confluence Application Link with JIRA: java.lang.IllegalArgumentException

[Tom Pryor]

I'm attempting to link Confluence with JIRA but when I attempt to add the application link I encounter the following error when entering the Server URL of JIRA:

The URL 'http:/jira.mysite.com/' is not valid. java.lang.IllegalArgumentException: Host name may not be null

First thing I noticed was the error only display a single forward slash after the http: but this is not how I entered the URL (The Server URL textbox contains: http://jira.mysite.com/)

If it helps I'm currently following the Here Be Dragons guide and I'm currently at Stage 3 - Installing Confluence. I've followed this guide with the exception that I'm using Crowd to provide authentication and SSO for all Atlassian applications rather than linking them with the JIRA directory.

Am I doing this incorrectly? How do I enable the application link in confluence?

Hey, Tom, have you found the solution?

From the confluence server, are you able to ping jira.mysite.com and access JIRA Homepage?

[Tom Pryor]

Confluence is running on the same server as JIRA. However, jira.mysite.com resolves to the external reverse proxy which points to 127.0.0.1:8080 relative to the confluence server.
