JDLG is a cross-platform graphical user interface for Eloquence DLG, implemented in Java. It requires an installed Java Runtime Environment (JRE).

JDLG is backward compatible to Eloquence ASCII DLG but provides new functionality such as an extended set of object classes and attributes as well as the ability to integrate Web content and to interface with a Web browser.

JDLG 2.0 was released in December 2018 along with Eloquence B.08.30, intended to improve overall performance due to a revised memory management along with an optimized DLG protocol implementation. It is is fully backward compatible and may also be used with previous Eloquence versions.

JDLG 2.0 requires Java version 5 or newer.

The Java Webstart feature may be used to easily deploy JDLG from a central system on the network, eliminating complex installation or update procedures. Please note that because Java Webstart is no longer included in Oracle^™ Java since version 11, we provide the EQWS utility as a simple and lightweight alternative.
