Re: [netcdf-java] GRIB file handling bug?

Hi Paul:

The problem is that the file has 2 GDSs in it, so two groups are made. 
Since you are writing to netcdf3, which doesnt support groups, it barfs. 
The error message is lame, i will fix that.

You should probably seperate the GRIB records to have unique GDSs.

The stable release will support netcdf-4 writing, if you have the C library.
