This occurs if the web client believes that it is running in a portal when in fact it is running in a 'normal' appserver.

A possible cause of this is an ommision of the mode detection filter in web.xml.

You should have the following:


<filter>
      <filter-name>Mode Detection Filter</filter-name>
      <filter-class>org.alfresco.web.app.servlet.ModeDetectionFilter</filter-class>
   </filter>
‍‍‍‍‍‍

The filter only gets called outside a portal server (portals don't support filters yet) and sets the 'inPortalServer' flag to false. So the only way you will see this error is if the flag is still set to true.

On alfresco1.2-jboss2.2 when I click on External Access URL (http://myhost:8080/alfresco/navigate/showSpaceDetails/workspace/SpacesStore/37bf51e8-a468-11da-aade-5d9bf12f5870)
I see this error:

Is there a solution?

Sorry but external URL access is not supported in the JSR-168 Portal deployment of Alfresco.

Thanks,

:shock: Ok, external URL access is not supported in the JSR-168 Portal deployment of Alfresco but it isn't accettable to have some link in the web client that gives such errors to users. How to remove not supported functionality from web-client :?:

Yes you are correct, the links should be hidden and errors handled from a JSR-168 environment. I have raised a JIRA task for this:
http://www.alfresco.org/jira/browse/AWC-604

Thanks,
