Source Distribution

The source distribution is available from http://www.hdfgroup.org/ftp/HDF5/hdf-java/src.

The source distribution includes the Java code to build HDFView, the Java HDF Object Package, and related HDF4 and HDF5 Object Packages. The source distribution also includes Java classes that declare the native methods for Java HDF Interface (JHI) and Java HDF5 Interface (JHI5) and C code that implements the native methods.

JHI requires the HDF4 library (binary), and JHI5 requires the HDF5 library (binary). These are not included in the HDF Java Products source distribution. The HDF libraries can be obtained from the HDF Downloads page.

Building the HDF Java Products from the source distribution is not an easy endeavor. Refer to the following the instructions for more details:
