ESB4Romulus is a set of tools that allows Roma to be integrated with ESB. The Roma Enterprise module allows the exposition of web services defined in Roma over the ESB. The service is exposed by annotating the service implementation class, following the Roma approach, and the module realizes everything is needed for creating the composite application to be deployed in the ESB. Roma Registry Module allows the registration of web services created with Roma on the target Service Registry Repository (WSO2). The web service is annotated by the developer, and the module will perform the registration when the service is deployed in a web container. Other tools contained in ESB4Romulus are: WSDL Navigator and General Services for Mashups.
