The DISPLAY environmental variable needs to be set to point at your
screen. 

In sh/ksh/bash, do something like:
DISPLAY=your.hostname:0.0

Or csh/tcsh:
setenv DISPLAY your.hostname:0.0

You'll also need to use xauth to give the remote machine access to your
screen. 

Of course, if you are just running communicator on the machine you have
your X server on then DISPLAY just needs to be set to ":0.0" (without the
quotes). You shouldn't need xauth in that case.
