Esteban,

Their might of been some confusion about your question, I was thinking that you 
meant levels for some reason. I looked in the grib grib2StdQuanties.xml table 
under Ocean Products, there are two different parameters for swell1 and swell2.
So you would have to extract them both separately. There is a file called 
IndexFormat.txt in the package home that explains the index in detail. The Java 
Grib is being refactored so some of the text indexing routines will be 
deprecated. There is a ShowGribIndex routine that gives the same type of output.
