New JavaScript data viewers...

It has become very difficult to run Java programs from a browser. We have an updated version of the data viewer that does not rely on Java.

Launch the new data viewers for:

Running Java --

Here's some help for launching Java WebStart ".jnlp" files.

Browsers have removed the ability to run embedded Java applets (such as these data viewers), so now they must be launched using JavaWS (Java Web Start).

The data viewers will be run outside the browser, but they are still subject to the same sandbox restrictions as when they are run as applets within the browser.

Clicking a data viewer link will download a small configuration file that is used to launch the viewer -- a ".jnlp file" (Java Network Launching Protocol). Some browsers will launch the app directly. All browsers will let you save these files, which you can then open like you would any app.

Note: As before, you will need to have a JRE (Java Run-time Environment) installed on your computer.

New - Jul2019Amazon Corretto is a no cost, open-source alternative to the JRE provided by Oracle. To launch our .jnlp files using Corretto you will also need to install a program called IcedTea.
