We are pleased to welcome you to Eloquence WEBDLG2, the new web browser interface for Eloquence DLG providing complete JDLG object and attribute compatibility.

WEBDLG2 allows to use Eloquence DLG applications from any computer or mobile device, no additional software installation required.

Enjoy!
The Eloquence Team

• WEBDLG2 provides complete JDLG 2.0 object and attribute compatibility.

• WEBDLG2 uses the WebSocket technology to implement a fast bidirectional low latency communication. WEBDLG2 provides the lowest possible application response times even under wide area network conditions.

• Dialogs are fully dynamic, the HTML document is updated in place and never reloaded. Applications can update the user interface at any time so that, for example, DLG DRAW now works as expected.

• WEBDLG2 uses a single server process, the eloqwebd2 server. The WEBDLG v1 mod_eloq Apache httpd web server module is no longer used, which removes the related complexities and performance bottlenecks.

• The eloqwebd2 server provides an internal web server to serve static documents, typically eliminating the need to configure and run a separate web server, e.g., Apache httpd.

• WEBDLG2 supports application development and debugging using the interactive eloq/eloqcore or the Eloquence IDE.

As of Eloquence B.08.40 2407-1, WEBDLG2 supports both desktop and mobile applications. All kinds of input devices (mouse, touch, pen/stylus) are now handled as expected, including context menus (triggered by a tap-hold / long press).
