Global JNDI Names

Global JNDI names are assigned according to the following precedence rules:

1. A global JNDI name assigned in the sun-ejb-jar.xml, sun-web.xml deployment descriptor file has the highest precedence. See Mapping References.

2. A global JNDI name assigned in a mapped-name element in the ejb-jar.xml, web.xml deployment descriptor file has the second highest precedence. The following elements have mapped-name subelements: resource-ref, resource-env-ref, ejb-ref, message-destination, message-destination-ref, session, and entity.

3. A global JNDI name assigned in a mappedName attribute of an annotation has the third highest precedence. The following annotations have mappedName attributes: @javax.annotation.Resource, @javax.ejb.EJB, @javax.ejb.Stateless.

4. A default global JNDI name is assigned in some cases if no name is assigned in deployment descriptors or annotations.

   • For component dependencies that must be mapped to global JNDI names, the default is the name of the dependency relative to java:comp/env. For example, in the @Resource(name="jdbc/Foo") DataSource ds; annotation, the global JNDI name is jdbc/Foo.
