Abstract
The present invention proposes a method and a corresponding system for scheduling invocation of web services from a central point of control. A scheduler accesses a workload database, which associates an execution agent and a descriptor with each submitted job. The descriptor identifies a desired web service, an address of a corresponding WSDL document, and the actual content of a request message to be passed to the web service. Whenever the job is submitted for execution, the scheduler sends the job's descriptor to the associated agent. In response thereto, the agent downloads the WSDL document that specifies the structure of the messages supported by the web service. The scheduler builds a request message for the web service embedding the desired content into the structure specified in the WSDL document. The agent sends the request message to an endpoint implementing the web service, so as to cause its invocation.
