Is it possible to interface W4 BPM Suite with a legacy application, e.g. with an accounting system on a mainframe?

Provided that the legacy application has an HTML interface, which becomes increasingly true, such an application can be invoked by either a frame or via another browser window. The application page and the controlling workflow page are linked by JavaScript scripting (or VBScript, if preferred).

3270 or 5250 terminal emulators providing access to applications processed on medium-range or large-scale IBM mainframes are already available for HTML-based face lifting.
