Build the sample, and then test it.
Start building the Stock Quote sample by creating the resources library and mediation module for your sample. Resources such as interfaces and business objects can be contained in libraries so that they can be easily shared by modules. Mediation modules contain mediation flow and Java components, exports to allow the target service in the mediation module to be called by other modules or clients, and imports which allow services external to the module to be invoked. The assembly diagram of the mediation module is used to wire the exports, components, and imports together to form the integrated service application.
