Setting up the Application Operational
Environment 
Purpose
You set up the application operational environment as part of the Web application configuration and assembling process. This consists of configuring the references to the resources that your Web application needs to use at runtime using the web.xml and web-j2ee-engine.xml deployment descriptors.
Configuring the references to various resources describes the way those resources are bound to the corresponding application’s naming environment. This allows application components to look the resources up in their source code. The Web Container uses the descriptive information about the environment entries that you have provided with the descriptors and provides an implementation of the JNDI naming context to the application, through which the environment entries are accessible.
Components of a Web application can reference both external and application-scoped resources. External resources are those that are deployed on the SAP J2EE Engine as part of a separate EAR file. The application-scoped resources are those that are deployed as part of the same enterprise application as the referring Web application.
For more information about the applications naming environment concept, see Java Ô 2 Enterprise Edition, version 1.3 and Java Ô Servlet, version 2.3 specifications at http://java.sun.com.
Process Flow
The setup of the application environment consists of the following configuration tasks:
· Configuring Environment Entries
· Configuring Resource Environment Entries
