Hi,
Have a look at the default data_dir. From data_dir\coverages\img_sample you can
find an image “usa.jpeg” which you can publish simply by creating a store and
layer. Perhaps the secret is in the file “usa.meta” which has contents:
Layer Name = Map Capture 1111440603125
Origin Longitude = -130.85168
Origin Latitude = 20.7052
Corner Longitude = -62.0054
Corner Latitude = 54.1141
Now we need some developer to tell how to write this .meta file. Obviously a
.prj file is needed as well.

Thank you very much for all the suggestions. We want to offer our users the
option to upload JPGs, but we might consider to re-code the image before
sending it to Geoserver. I assume the best option is Geotiff using tiles and
overviews.
@Jukka: I have tried several variation, such as renaming the .wld to .jgw, the
.jpg to .jpeg, including or excluding the .xml generated by gdal, etc. No one
worked.
In any case, I will open a ticket as suggested.

By the looks of this error it seems that the Java own JPEG reader cannot
recognize this JPEG variant.
Never seen this error, but I agree with Jukka, serving world files is a recipe
for slowness, there
is no inner tiling, every time one has to go, read and un-compress the entire
image even if
the area of interest is a small bit.
Anyways, as an alternative to try out, you could install the turbo-jpeg
extension:
http://docs.geoserver.org/latest/en/user/extensions/libjpeg-turbo/index.html
It is advertised as an output format, but as far as I know the library also
comes as a reader
which might replace the Java built in one. You might give a go at it and see if
this
one car read your file.
In any case, I'd open a ticket and attach a sample file that cannot be opened.
Cheers
Andrea
