My Java code, using ncCore4.1.jar, opens a NetCDF file:

        NetcdfFileWriteable netcdfFile;
        try
        {
            netcdfFile = NetcdfFileWriteable.openExisting(netcdfFileName);
        }
        catch(final IOException e)
        {

throw new IOException(netcdfFileName + " was not found oris not a valid netcdf file.");

        }

Most of time it is working. However, occasionally, I got this error:

*java.lang.NoSuchMethodError:ucar.nc2.NetcdfFileWriteable.openExisting(Ljava/lang/String;)Lucar/nc2/NetcdfFileWriteable;version: 2011.01, build: 31117 Jun30, type: stable, jre: 1.6.0_25, *

Since the error occurs once in a while, which makes my debug very hard,I am asking if anybody knows the cause of it.


Thank you very much.

Best,
