Pushkar,

The problem is that the internal MapServer drawRaster() code recognises
this as a JPEG and calls drawJPEG() on it which reports that JPEG support
is not available.  I used to have the same problem with TIFF, but I modified
mapraster.c to avoid trying drawTIFF() if tiff was not configured and gdal was.
I have just committed a similar change for JPEG.

Please get the latest mapraster.c from CVS and rebuild.  It shouldn't be
necessary to reconfigure.  If you don't have ready access to CVS let me know
and I will email it directly to you.

Sorry for the confusion ... I forgot about this "issue".

Best regards,
