You do not need to start the server anymore. Because Worklight Server V6.0.0 and later can support multiple Worklight projects, there are no longer Start Server and Stop Server menu options that are associated directly to the Worklight project. Instead, the server that is associated with a Worklight project is started automatically (if the server is not already running) when you perform an action against that server or adapter. For example, the target server starts when you use the Worklight Studio command Run As > Run on Worklight Development Server.
