A InitialContext can be declared via xml in the
`<tomee-home>/conf/tomee.xml` file or in a `WEB-INF/resources.xml` file
using a declaration like the following. All properties in the element
body are optional.

[source,xml]
----
<JndiProvider id="myInitialContext" type="javax.naming.InitialContext">
</JndiProvider>
----

Alternatively, a InitialContext can be declared via properties in the
`<tomee-home>/conf/system.properties` file or via Java VirtualMachine
`-D` properties. The properties can also be used when embedding TomEE
via the `javax.ejb.embeddable.EJBContainer` API or `InitialContext`

[source,properties]
----
myInitialContext = new://JndiProvider?type=javax.naming.InitialContext
----

Properties and xml can be mixed. Properties will override the xml
allowing for easy configuration change without the need for $\{} style
variable substitution. Properties are not case sensitive. If a property
is specified that is not supported by the declared InitialContext a
warning will be logged. If a InitialContext is needed by the application
and one is not declared, TomEE will create one dynamically using default
settings. Multiple InitialContext declarations are allowed. # Supported
