Using External Methods

You can write external user-methods (or routines) for JADE classes. External routines can be written in any language that can create a Dynamic Link Library.

The .NET DLL files or executables to be used with:

32-bit JADE executables must be built for the x86 (32-bit) platform.
64-bit JADE executables must be built for the x64 (64-bit) platform.

For details, see "Writing External Methods", in the following section, and "JADE Application Programming Interface (API)", in Chapter 3 of the JADE Object Manager Guide. For details about low‑level C API to obtain JADE initialization file information, directory information, and to convert JADE characters to an ANSI or Unicode string, see "C-Level Application Programming Interface (API)", in Chapter 6 of the JADE Object Manager Guide. For details about adding an external method to a class, see "Adding External Methods to Classes", in Chapter 8 of the JADE Development Environment User’s Guide.

Before you can create a new external method, the library containing your library file must already exist and you must select the class to which the method is to be added. You can use the same library to import both external methods and external functions, if required.

In JADE thin client mode, an external method call made from JADE logic executes on the application server workstation and not that of the presentation client.
