A design surface is provided that displays a graphical representation in a toolbox of components that can be used to create a mashup application, at least one of the components being a wrapper to an existing web service. The visual mashup designer displays operations that each component placed on the design surface has available. A graphical mapping utility allows a user to graphically map outputs of a selected operation from a first component to inputs of a selected operation from a second component. When placed on the design surface, each component is displayed in a respective container. The respective container displays one or more operations that the respective component supports. When the user selects a particular operation for a particular component, the system displays one or more input parameters and output parameters for a particular operation.
