[Building Sakai] Problem with chat tool

[Tom Helmer Hansen]

Hi Sakai-dev

We have a problem with the chat tool in Sakai 2.6.0. When the tool is 
shown on a page it fails with the message inserted below. The entire 
tomcat folder is copied from the build machine where everything works as 
it should. Only thing changed when moving to the prod-server is changing 
some hostnames.
