Remote Issue Link between JIRA and Confluence shows "Failed to load" in JIRA

[Henning Tietgens]

Hi,

we have connected our JIRA 5.1.8 and Confluence 4.3.2 systems through an Application Link. If I insert a JIRA issue into a Confluence page there is automatically a remote issue link created within the JIRA issue.

This remote issue link shows "mentioned in Wiki Page Failed to load". Within Confluence the Issue information (key, summary, title) is displayed correctly.

Within the logfile there is following error while JIRA tries to display the remote issue link:

2013-01-17 16:03:08,186 http-8443-83 ERROR [...] /rest/viewIssue/1/remoteIssueLink/render/11101 [viewissue.issuelink.rest.RemoteIssueLinkResource] Error occurred while generating final HTML for remote issue link: java.lang.NullPointerException

Both systems are configured to use SSL.

First we tried a Trusted Applications link only, than added OAuth and than Basic Access. So all three ways to configure an Application Link are configured in both systems.

Any ideas, what could be wrong or how to get more informations about thre problem?

Thanks,

Henning

No, it's still an issue. Sometimes it's working partly, sometimes not. One thing is to make sure both servers have the SSL certificates of the other server installed. But unfortunately that's not all...

@Henning Tietgens Did you find the root cause?

[Ruchi Tandon]

I found this KB article that seems to be relared to the problem in your case.

I hope this helps!

[Henning Tietgens]

Thanks, but we removed any IPs from the Trusted Application settings to not restrict the access and to remove potential problems. So IMO this could not be the problem...

If I try to add a Confluence link and search for a Confluence page I get this error in the log:

There are several possible causes for this, and seems like you have already checked a number of them. One thing you might want to check is in Confluence, make sure you have Remote API (XML-RPC & SOAP) option enabled, from General Configuration.

[Henning Tietgens]

Thanks, our Confluence Admin checked that and it's enabled. Any other hints?

I am also seeing this issue and not yet able to determine why
