This document lists the document formats that will be used by the Java Platform, Enterprise Edition (Java EE) deployment descriptors described by Java EE 5 and later specifications. Prior to the J2EE 1.4 specifications, each Deployment Descriptor was required to be valid with respect to a specific DTD that describes the Deployment Descriptor. The DTDs are found in the J2EE section of this document. Starting with the J2EE 1.4 specification, each specification requires its Deployment Descriptor be validated with respect to an XML Schema that is listed in the J2EE 1.4 document and this document. Note that deployment descriptors defined by previous versions of the Java EE specification must also be supported by all current Java EE products, and must continue to be validated against the corresponding DTD or schema. Note that not all deployment descriptors are updated for every release of Java EE, in which case the deployment descriptor from the previous version is used.

The Java EE specification also requires support for the Java Persistence API and the Bean Validation API. The Java Persistence API Schemas are available at http://xmlns.jcp.org/xml/ns/persistence/. The Bean Validation API Schemas are available at http://www.jboss.org/xml/ns/javax/validation/configuration/.

This document describes how to use the Java EE schemas and provides a list of XML Schemas for each deployment descriptor.

All Java EE 7 and newer Deployment Descriptor Schemas share the namespace http://xmlns.jcp.org/xml/ns/javaee/. Each schema document contains a version attribute that contains the version of the specification. For example, the XML Schema document for the Servlet specification contains the version attribute value "3.1", pertaining to the specific version of the specification as well as the schema document itself.

Each Java EE XML Schema document's file name contains the specific version of the related specification. This is introduced for convenience to locate specific versions of the schema documents. However, Deployment Descriptor instances are not required to refer to a specific file. Instead, an instance must specify the version of the corresponding specification by using the version attribute. For example, servlet Deployment Descriptor instances that must be processed with the servlet 3.1 version must indicate the version within the version attribute of the instance document, for example, "3.1". The Deployment Descriptor processors use the version information to choose the appropriate version of the schema document(s) to process the Deployment Descriptor instances.

A specific version of the Java EE specification contains a set of deployment descriptor schemas to constitute the Java EE Schema. The common definitions are contained in the javaee_<version>.xsd document that may be included by several Java EE Deployment Descriptor schemas.

This table contains the XML Schema components for Java EE 7 schema. All new schemas are in the http://xmlns.jcp.org/xml/ns/javaee/ namespace. Most older schemas remain in the http://java.sun.com/xml/ns/javaee/ namespace.

This table contains the XML Schema components for Java EE 6 schema. All of these schemas are in the http://java.sun.com/xml/ns/javaee namespace.

This table contains the XML Schema components for Java EE 5 schema. All of these schemas are in the http://java.sun.com/xml/ns/javaee namespace.

XML Schemas specified by the J2EE 1.4 specification are available at http://java.sun.com/xml/ns/j2ee/.

DTDs specified by the J2EE 1.3 specification are available at http://java.sun.com/dtd/.

DTDs specified by the J2EE 1.2 specification are available at http://java.sun.com/j2ee/dtds/.
