Pablo-I'm not sure about the RC stuff, but it looks like you are getting a NullPointerException at line 39 which means that uwindgrid is null. I suspect that is due to the variable name changes in 4.3. If findGridDatatype can't find the grid, it will return null.

Hello,
I've completed the recommended emergency shutdown of my project, as I
was working with grib files and 4.2 API version ;-)
Once updated my build path to the new 4.3 version, I'm having some
problems compiling the same code:
Code:
37 GridDataset gds = GridDataset.open("~/myfile.grb");
38 GridDatatype uwindgrid = gds.findGridDatatype("U_component_of_wind");
39 GridCoordSystem gcs = uwindgrid.getCoordinateSystem();
Error message:
Feb 10, 2012 7:11:29 PM ucar.nc2.util.rc.RC loadDefaults
INFO: No .rc file found
Exception in thread "main" java.lang.NullPointerException
at Test.main(Test.java:39)
I've checked the new javadoc and all the used methods seem to be the
same, but I can't find any reference to ucar.nc2.util.rc.RC class to
trace back the NullPointerException... Any suggestions?
Thank you everybody for your help,
Pablo Rozas
