The OpenROAD Server provides a set of Microsoft’s COM objects that expose a client-callable interface to 4GL SCPs. Using COM objects helps to maximize the number of client environments that can take advantage of the OpenROAD Server facilities, and it leverages the extensive support COM provides for local and remote server activation, marshaling of parameters, and provides configurable security controls.

COM provides a platform-independent, language-neutral interface for the OpenROAD Server. Using COM enables Java, .NET, JSP, ASP.NET and many other environments to access 4GL logic hosted in the OpenROAD Server.
