Hello Dany,
If you are just reading GRIB data, I'd recommend Unidata's NetCDF Java
Library. This includes decoders for GRIB 1 and GRIB 2. The data are
decoded into the NetCDF data structure, which is basically arrays of
data. The documentation is good with lots of examples.
Once in the NetCDF structure, you could populate a WritableRaster and
create a GridCoverage from the desired "slice" of data. The NetCDF
(and GRIB) structure often represents multiple "stacked" grids in the
x, y, z and time dimensions.

Hi guys.
I'm searching some documentations about the GRIB FORMAT because my
knowledge about that is actually very weak.
Actualy I'm interested to know how metadata are contained in a record
of this kind of format.
.....I have understood (I hope...) that a GRIB record is composed of 6 sections:
Indicator
section
Product
Definition Section
Grid
Description Section (optional)
Bit
Map Section (optional)
Binary
Data Section
End
Section (7777)
And metadata are contained in the first 2 sections.
Can someone show me a link or send a document where I can find some
examples of these metadata and their arrangement within the record?
If you need to add some observations you are the welcome ^_^
Thx a lot
regards,
Dany
