receiving, at a computer, a request to initialize an application, the application including one or more legacy components of the legacy application components that are not developed to communicate with web service clients of the web service environment;

based on the initializing of the application that initializes the one or more legacy components, identifying that an administrative configuration setting indicates that the dynamic web service for the one or more legacy components is to be generated upon the initialization of the application;

based on the administrative configuration setting of the administrative event, accessing metadata that describes an interface description for communicating with the one or more legacy components;

using the metadata to automatically generate the dynamic web service consistent with the interface description for allowing the web service clients of the web service environment to communicate with the one or more legacy components through a translation process;

receiving a web service request message from the web service clients, the web service request message including one or more operations for requesting services offered by the one or more legacy components;

based on the one or more operations, using the dynamic web service to make one or more legacy calls to the one or more legacy components; and

upon termination of the application, automatically terminating the dynamic web service such that upon subsequent initialization of the application, the dynamic web service is regenerated based on the metadata that exists at a time of the subsequent initialization such that any changes to the interface descriptor for communicating with the one or more legacy components that occurred subsequent to the initialization of the application will be reflected in the regenerated dynamic web service.
