  • New Release of HDF5 Java Products

    A new release of the HDF5 Java Products is now available from: See below for details on what is new with this release.

    H5View: *New Features*

    Version 2.0 of the H5View tool introduces visual editing capabilities. The editing features include:

    h5gen: XML to HDF5 (*New Product *)

    The h5gen utility reads an XML description of an HDF5 file and generates the corresponding HDF5 file. The XML input must conform to the HDF5 Document Type Definition (DTD) (http://hdf.ncsa.uiuc.edu/DTDs/HDF5-File.dtd).

    The h5gen tool uses the Xerces XML parser developed by the Apache Software Foundation (http://www.apache.org/).

    Java HDF5 Interface (JHI5) now uses HDF5-1.2.2

    The Java HDF5 Interface (JHI5) has been updated to HDF5-1.2.2. Due to minor changes in the HDF5 API, the JHI5 is not compatible with earlier releases of HDF5-1.2.

    Note that linking the new JHI5 with an older revision of HDF5 may result in loading errors on some platforms that indicate the library cannot be found. This can be caused by mismatches between the C function names in Java and the function names in the library.

    Revisions to the HDF5 XML Document Type Definition (DTD)

    Development of the h5gen tool uncovered several 'bugs' in the HDF5 DTD, which have been changed. For information about the changes, see:
