Tomcat provides a JNDI InitialContext implementation instance for each web application running under it, in a manner that is compatible with those provided by a Java Enterprise Edition application server. The Java EE standard provides a standard set of elements in the /WEB-INF/web.xml file to reference/define resources.

See the following Specifications for more information about programming APIs for JNDI, and for the features supported by Java Enterprise Edition (Java EE) servers, which Tomcat emulates for the services that it provides:

• Java Naming and Directory Interface (included in JDK 1.4 onwards)
• Java EE Platform Specification (in particular, see Chapter 5 on Naming)

The following elements may be used in the web application deployment descriptor (/WEB-INF/web.xml) of your web application to define resources:

• <env-entry> - Environment entry, a single-value parameter that can be used to configure how the application will operate.
• <resource-ref> - Resource reference, which is typically to an object factory for resour
