Launch JGloss with Java Web Start

Launch JGloss

You can launch the latest version of JGloss directly from the web site using Java Web Start. When the Java runtime is correctly installed, you can open the above link with the javaws application. It will automatically download the required libraries and launch JGloss. This works even if you have disabled the Java Plugin in your browser.

JGloss 2.1.2

JGloss 2.1.2, last updated on 5/9/15, is the most recent release.

The dictionary lookup part of JGloss is also available as a separate application: JDictionary. You can use this if for example you want to offer your language students a dictionary lookup program, but not the (too) easy text parsing of the full JGloss.

Here are some links to dictionary files which can be used with JGloss. If you know of dictionaries not listed here, drop me a note.
