As stated in my project my aim was to study geotools and geotoolkit and choose the best of them and use that for netcdf reading.
While begging for complex data in the netcdf-cf mailinglist, I meet Mr.Jon Blower, Technical Director of the Reading e-Science Centre and lead of the ncWMS project. He adviced me to look into his code, which I did.
After bringing the web part code to desktop code, I was able to play a bit with several datasets and was amazed. One thing that attracted me also was the possibility to support vector data and have those nice arrows defining the directional data.
Well, because of this and several other things I decided to adapt the ncWMS code for the needs of this project (visualization in uDig and use of the data for analyses in JGrass).
To give you an idea, here an extract from the remote OPeNDAP dataset (oh yes, we can access remote data, did I forget to mention that? 
) that are located here: http://mersea.dmi.dk/thredds/dodsC/ecoop/BalticBestEstimate.html

Lots of thanks go to Jon Blower, that has been incredibly kind, helpful and patient to help me to get started.
