Abstract: A method for codeless development of an application includes registering one or more actions in a registry. Each action is coded in a reusable block of code, each action having an action definition including an action type name, an input parameters map, and an output parameters map. The method further includes performing an action type name look up in the registry for an invoked action with an action service ensuring that a number of arguments included in the action definition matches a number of arguments specified by the action type, passing an input to and receiving a return value from the invoked action, updating the output parameters map included in the definition of the invoked action, and returning the updated output parameters map to an application in development for updating processing variables in the application.

Abstract: In one general aspect, a method can include creating an action, the creating including annotating a block of code with metadata, and encapsulating the annotated block of code into a reusable building block of code. The method can further include publishing the action, the publishing including registering the action in a service registry. The method can further include dynamically discovering the action in the service registry by an application during runtime, invoking the action by the application, and executing the action by the application, the executing performing a method specified by the action.
