The NetCDF-Java Library is a Java interface to NetCDF
files, as well as to many other types of scientific data formats.
The library is freely available and the source code is released under the (MIT-style) netCDF C library license. Previous versions use the GNU Lesser General Public License (LGPL).
The preferred place to ask questions, discuss problems and features and get support is in the NetCDF-Java email list, which you can subscribe to from this page. Also you might want to search or browse previous netCDF-Java support questions.
The NetCDF-Java library implements a Common Data Model (CDM), a generalization of the NetCDF, OpenDAP and HDF5 data models. The library is a prototype for the NetCDF-4 project, which provides a C language API for the "data access layer" of the CDM, on top of the HDF5 file format. The NetCDF-Java library is a 100% Java framework for reading netCDF and other file formats into the CDM, as well as writing to the netCDF-3 file format. The NetCDF-Java library also implements NcML, which allows you to add metadata to CDM datasets, as well as to create virtual datasets through aggregation.
Which jar files do I need? See Jar Dependencies for explanation of which library you want.
Which version of Java? All active versions (2.2.22 and 4.0) require Java 5 or above. Performance and stability is improved in version 6, and so the latest version of Java 6 is recommended. NetCDF-Java version 4.1 will likely require Java 1.6. If you are stuck with Java 1.4, you can use the NetCDF-Java 2.2.20 release, but no support or bug fixes are done on that version.

The NetCDF-Java library can read these file types and remote access protocols.
