[[EE]]
= EE Subsystem Configuration
:leveloffset: +1
The EE subsystem provides common functionality in the Jakarta EE platform,
such as the EE Concurrency Utilities (JSR 236) and `@Resource`
injection. The subsystem is also responsible for managing the lifecycle
of Jakarta EE application's deployments, that is, `.ear` files and configuration of global directories to share common libraries across all deployed applications.

The EE subsystem configuration may be used to:

* customise the deployment of Jakarta EE applications
* create EE Concurrency Utilities instances
* define the default bindings

The subsystem name is ee and this document covers EE subsystem version
`5.0`, which XML namespace within WildFly XML configurations is
`urn:jboss:domain:ee:5.0`. The path for the subsystem's XML schema,
within WildFly's distribution, is `docs/schema/jboss-as-ee_5_0.xsd`.
