CDF JNLP Libraries


This site contains Common Data Format (CDF) libraries packaged for convenient use by Java applications which need to read or write CDF files.  The libraries are packaged for use by means of the Java Network Launching Protocol (JNLP).  For more information concerning JNLP, refer to the Java Platform, Standard Edition JDK documentation.  The libraries are made available to support a number of platforms

How to use

To make use of these libraries, simply develop and deploy your application as a JNLP application. Your application should contain code similar to the following that is executed before any access to CDF classes:

Also, your application's JNLP file should include a resource extension reference to one of the CDF JNLP files described below.  Here is a example JNLP file that shows a reference to a CDF JNLP file.

Notes:
  1. The Mac PPC platform is being dropped since I longer have access to a computer that can produce PPC libraries.  However, CDF 3.4 can be used to read CDF version 3.5 files.
  2. Beginning with release 3.3.1, the JNLP file is also signed to eliminate security warnings introduced in a newer releases of Java WebStart.
  3. Beginning with release 3.6.0.3, the Linux Jars require GLIBC_2.7 (RHEL 6).  Earlier releases required GLIBC_2.3 (RHEL 5).
  4. CDF 3.6 or higher should be used for files containing TT2000 type variables.  Earlier versions do not put sufficient metadata in the file to verify the validity of TT2000 values.

CDF Releases

The following releases of CDF are available via JNLP.
