Web Services are typically installed as part of an Enterprise Application. The Enterprise Application can be either archived as an EAR, or be in exploded directory format. The Web Service itself is packaged as either a Web Application or an EJB, depending on its implementation. The Web Service can be in archived format (WAR or JAR file, respectively) or as an exploded directory.
A Web Service does not have to be installed as part of an Enterprise application; it can be installed as just the Web Application or EJB. However, BEA recommends that users install the Web Service as part of an Enterprise application. The WebLogic Ant task used to create a Web Service (jwsc) always packages the generated Web Service into an Enterprise application.
To view the Web Services installed in your domain:
The right pane displays a table of Deployments, or applications that are currently installed in your domain. The Type column specifies the type of application: Enterprise, Web, or EJB. Web Services are packaged inside one of these types of applications.
