OK I've answered my own question and it has to do with the differences between Firefox and IE and how they handle the proxy settings. Firefox kept giving proxy errors so out of curisoity I tried IE 8 and things started working. I then changed the URL and Host name values in both RTC and RQM to be

URI = https://servvername:9443/jazz
Hostname = servername

Once both RTC and RQM were configured adding links by IE8 worked but in Firefox it complained about unable to load URL.

I then added the server names in question into the "do not use proxy for" edit box in the connection settings of IE and suddenly everything in Firefox worked the same as IE 8.

Problem resolved, So if you get this problem try and different browser and check you proxy settings if you are using a proxy.

I've been struggling with getting cross server communication working between RTC 2.0.0.0 and RQM 2.0.0.1. I have followed the instructions laid out in http://jazz.net/library/techtip/304 and have verified all recommended checks of rootservices and Friends xml along the way.

I am able to see projects listed in the Links dialogus from RTC and appear to be able to add the links, but when I save the link the following error is generated:

Creating project area back link failed.

Unable to load URL: /jazz/proxy?uri=https%3A%2F%2FAMPEPSITTASD01.au.amp.local%3A9443%2Fjazz%2Fprocess%2Fproject-areas%2F_stJVgGfqEd24KMoDcFLfcQ%2Flinks, Status: 403

In RQM when trying to add a link between projects back to RTC, the Link dialog displays the following error:

Failed to read friends resource:
Unable to load URL: /jazz/proxy?uri=https://AMPEPSITTASD01.au.amp.local:9443/jazz/friends, Status: 403

If I check the following friends URL https://ampepsittasd01.au.amp.local:9443/jazz/friends for the RQM server, I get the following back XML response:

<rdf>

<jd>

<jfs>false</jfs>

<jd>

<dc>https://ampaustdccpv3.au.amp.local:9443/jazz</dc>

</jd>

</rdf>

but if I type the following into the browser:

https://ampaustdccpv3.au.amp.local:9443/jazz/proxy?uri=https://AMPEPSITTASD01.au.amp.local:9443/jazz/friends

The browser responds with the following:

The proxy is not configured to allow the request to https://AMPEPSITTASD01.au.amp.local:9443/jazz/friends

Does anybody have any ideas why the RQM doesn't seem to be able to read it's friends list and reports a Status 403 and why RTC can't save the relevent details of the linkages?

Does anyone know what proxy it is using when its says the proxy is not configured to allow requests to?

RQM and RTC are running in Websphere 6.0.0.27

Any assistance would be greatly appreciated.
