Hi Pauline,
I think you have an old version of the grib-*.jar library on your
classpath before the netcdf-*.jar file. The
ucar.unidata.io.RandomAccessFile class is distributed in both library
files and if those two libraries aren't in sync it can cause trouble.
The versions in netcdfAll-2.2.20.zip should match up. Here's the version
info from the grib jar file:
Built-On: 2007-05-15 13:13:58
Implementation-Version: 5.1.03

Hi all,
I'm having trouble trying to open a nc.zip file. I'm using the latest
version of the NetCDF library (netCDF 2.2.20). Do I need to download
another library for the getRandomAccessFile method?
When I open it, I get the following error message:
Exception in thread "main" java.lang.NoSuchMethodError:
ucar.unidata.io.RandomAccessFile.getRandomAccessFile()Ljava/io/RandomAccessFile;

.....
Interestingly, it works fine on TDS - when I browse for the file in TDS,
it's able to show all the attributes of the files. In fact, the file
doesn't even show up a zip file. Maybe there's another magical method
for opening the file? I'm opening files using the method:
GridDataset.open ("file:///" + dirName);
Thanks for any help in advance :)
Cheers,
-Pauline.
