Workflow-based applications consists of a process model and a set of port types. When such an application is deployed into an appropriate environment, a deployment descriptor is used to specify which ports should be used when carrying out a process instance. When a new process instance is created, the workflow management system retrieves the deployment descriptor and fixes the actual ports to be used for the individual port types; that means the deployment descriptor is bound at process instance creation time. As a result, running process instances are not affected by port changes reflected in the deployment descriptor. This behavior may be too restrictive, in particular if processes are long-running. It is proposed to add the capability of specifying the binding time to the deployment descriptor .
