Autostart of Julia process is not implemented yet. You can see this by
trying to switch to process buffer with C-c C-z, which would give an
appropriate warning. Normally C-c C-z would autostart the proc.

Just do M-x julia to get the process running. Then ESS evaluation
command will automatically connect to it.

This could happen when there is only one process running. This will be
fixed soon. For now you can just simply switch associated processes with
C-c C-s. 

The last point is that you better user C-c C-c to evaluate whole
paragraphs because julia cannot accumulate individual lines as R does
(at least it couldn't 2 months ago).
