Configuring Resources

When accessing resources such as a data source from a Web application through Java Naming and Directory Interface (JNDI), you can map the JNDI name you look up in your code to the actual JNDI name as bound in the global JNDI tree. This mapping is made using both the web.xml and weblogic.xml deployment descriptors and allows you to change these resources without changing your application code. You provide a name that is used in your Java code, the name of the resource as bound in the JNDI tree, and the Java type of the resource, and you indicate whether security for the resource is handled programmatically by the servlet or from the credentials associated with the HTTP request. You can also access JMS module resources, such as queues, topics, and connection factories. For more information see, "Configuring JMS Application Modules for Deployment" in Configuring and Managing JMS for Oracle WebLogic Server.

To configure resources:

1. Enter the resource name in the deployment descriptor as you use it in your code, the Java type, and the security authorization type.

2. Map the resource name to the JNDI name.The following example illustrates how to use an external data source. It assumes that you have defined a data source called accountDataSource. For more information, see "JDBC Data Sources " in Oracle WebLogic Server Administration Console Help.
