M3 Web Services Server is the runtime engine for M3 Web Services, which are wrappers for the business functionality provided by supported backend applications such as M3 Business Engine.
The M3 Web Services Grid Management pages provide some basic administrative capabilities. For example, you can view deployed web services, check the server setup for errors, do some basic configuration management, and manage web service security.
To create your own web services, you must also install the M3 Web Services Designer component, which allows you to design, model, deploy, and test web services.
