Re: [netcdf-java] Problems getting Coordinate System in v4.3

Thanks Don, I didn't notice the changes in the variable names. The RC
stuff remains as an INFO: No .rc file found, so I will not pay much
attention to it.
I think the name changes will trip up a lot of people, so you're in good company. ;-) 

John will have to chime in on the RC issue.

Don


    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,
