Configuring Resources in a Web Application

The resources that you use in a Web application are generally deployed externally to the Web application. JDBC data sources can optionally be deployed within the scope of the Web application as part of an EAR file.

To use external resources in the Web application, you resolve the JNDI resource name that the application uses with the global JNDI resource name using the web.xml and weblogic.xml deployment descriptors. (The web.xml file is located in the WEB-INF directory of your Web application.) See Section 7.2, "Configuring Resources" for more information.

You can also deploy JDBC data sources as part of the Web application EAR file by configuring those resources in the weblogic-application.xml deployment descriptor. Resources deployed as part of the EAR file with scope defined as application are referred to as application-scoped resources. These resources remain private to the application, and application components can access the resource names by adding
