This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

The graphics created by the MATLAB Web Server in the WEBPEAKS demo, are JPEG images. JPEG images are created by obtaining a screen capture of MATLAB figures, and therefore require a display environment on the UNIX and Linux platforms.

A request to allow MATLAB to run in a display free environment has been forwarded to our development staff as an enhancement for a future version of MATLAB and the MATLAB Web Server.

There are no known workarounds at this time.
