'''Jakarta EE''', formerly '''Java Platform, Enterprise Edition''' ('''Java EE''') and '''Java 2 Platform, Enterprise Edition''' ('''J2EE'''), is a set of specifications, extending [[Java SE]]<ref>{{cite web |url=http://docs.oracle.com/javaee/6/firstcup/doc/gkhoy.html |title=Differences between Java EE and Java SE - Your First Cup: An Introduction to the Java EE Platform |publisher=Docs.oracle.com |date=2012-04-01 |access-date=2012-07-18}}</ref> with specifications for enterprise features such as [[distributed computing]] and [[web service]]s.<ref>{{cite web |url=https://www.oracle.com/technetwork/java/javaee/overview/index.html |title=Java EE Overview |access-date=February 26, 2017 |publisher=[[Oracle Corporation]]}}</ref> Jakarta EE applications are run on [[reference implementation|reference runtime]]s, which can be [[microservices]] or [[application server]]s, which handle transactions, security, scalability, [[Concurrency (computer science)|concurrency]] and management of the components they are deploying.

Jakarta EE is defined by its [[program specification|specification]]. The specification defines [[API]]s (application programming interface) and their interactions. As with other [[Java Community Process]] specifications, providers must meet certain conformance requirements in order to declare their products as ''Jakarta EE compliant''.

Examples of contexts in which Jakarta EE referencing runtimes are used are: [[e-commerce]], [[accounting]], [[banking]] [[information system]]s.

== History ==
The platform created by [[Sun Microsystems]] was known as ''Java 2 Platform, Enterprise Edition'' or ''J2EE'' from version 1.2, until the name was changed to ''Java Platform, Enterprise Edition'' or ''Java EE'' in version 1.5.

After [[acquisition of Sun Microsystems by Oracle Corporation|Sun was acquired in 2009]], Java EE was maintained by [[Oracle Corporation|Oracle]] under the [[Java Community Process]]. On September 12, 2017, [[Oracle Corporation]] announced that it would submit Java EE to the [[Eclipse Foundation]].<ref>{{cite web |last=Waters |first=John K. |date=2017-09-12 |df=mdy |url=https://adtmag.com/articles/2017/09/12/java-ee-moving-to-eclipse.aspx |title=Java EE Is Moving to the Eclipse Foundation |website=ADTmag |access-date=2017-09-13}}</ref> The Eclipse top-level project has been named Eclipse Enterprise for Java (EE4J).<ref>{{cite web |url=https://www.eclipse.org/ee4j/faq.php |title=EE4J FAQ |first=Wayne |last=Beaton |website=[[Eclipse Foundation]]}}</ref> The Eclipse Foundation could not agree with Oracle over the use of {{code|javax}} and Java trademarks.<ref>{{cite web |last=Milinkovich |first=Mike |date=2019-05-03 |df=mdy |url=https://eclipse-foundation.blog/2019/05/03/jakarta-ee-java-trademarks/ |title=Update on Jakarta EE Rights to Java Trademarks |department=Blog |work=Life at Eclipse |access-date=2024-07-25}}</ref> Oracle owns the trademark for the name "Java" and the platform was renamed from Java EE to Jakarta EE.<ref>{{cite news |last1=Chirgwin |first1=Richard |date=2018-03-04 |df=mdy |url=https://www.theregister.co.uk/2018/03/04/java_ee_is_now_jakarta_ee/ |title=Java EE renamed 'Jakarta EE' after Big Red brand spat |department=Software |work=[[The Register]] |access-date=19 March 2018}}</ref><ref>{{cite news |last1=Vaughan-Nichols |first1=Steven J. |date=2018-03-05 |df=mdy |title=Good-bye JEE, hello Jakarta EE |url=https://www.zdnet.com/article/good-bye-jee-hello-jakarta-ee/ |department=Linux and Open Source |work=[[ZDNet]] |access-date=2020-07-10}}</ref> The name refers to the largest city on the island of [[Java]] and also the capital of Indonesia, [[Jakarta]].<ref>{{cite web |last=Tijms |first=Arjan |date=2020-02-27 |df=mdy |title=Transition From Java EE to Jakarta EE |url=https://blogs.oracle.com/javamagazine/post/transition-from-java-ee-to-jakarta-ee |department=Java Magazine |website=blogs.oracle.com |access-date=2024-07-25}}</ref> The name should not be confused with the former [[Jakarta Project]] which fostered a number of current and former Java projects at the [[Apache Software Foundation]].

== Specifications ==
Jakarta EE includes several specifications that serve different purposes, like generating web pages, reading and writing from a database in a transactional way, managing distributed queues.

The Jakarta EE APIs include several technologies that extend the functionality of the base [[Java Platform, Standard Edition|Java SE]] [[Application programming interface|API]]s, such as [[Jakarta Enterprise Beans]], [[Jakarta Connectors|connectors]], [[Jakarta Servlet|servlet]]s, [[Jakarta Server Pages]] and several [[web service]] technologies.

=== Web specifications ===
* [[Jakarta Servlet]]: defines how to manage HTTP requests, in a synchronous or asynchronous way. It is low level and other Jakarta EE specifications rely on it;
* Jakarta WebSocket: API specification that defines a set of APIs to service [[WebSocket]] connections;
* [[Jakarta Faces]]: a technology for constructing user interfaces out of components;
* [[Jakarta Expression Language]] (''EL'') is a simple language originally designed to satisfy the specific needs of web application developers. It is used specifically in Jakarta Faces to bind components to (backing) beans and in Contexts and Dependency Injection to named beans, but can be used throughout the entire platform.

=== Web service specifications ===
* [[Jakarta RESTful Web Services]] provides support in creating web services according to the [[Representational State Transfer]] (REST) architectural pattern;
* Jakarta JSON Processing is a set of specifications to manage information encoded in JSON format;
* Jakarta JSON Binding provides specifications to convert JSON information into or from Java classes;
* [[Jakarta XML Binding]] allows mapping XML into Java objects;
* [[Jakarta XML Web Services]] can be used to create SOAP web services.

=== Enterprise specifications ===
* Jakarta Activation (''JAF'') specifies an architecture to extend component Beans by providing data typing and bindings of such types.
* Jakarta Contexts and Dependency Injection (''CDI'') is a specification to provide a [[dependency injection]] container;
* [[Jakarta Enterprise Beans]] (''EJB'') specification defines a set of lightweight APIs that an object container (the EJB container) will support in order to provide [[Transaction processing|transactions]] (using [[Jakarta Transactions|JTA]]), [[remote procedure call]]s (using [[Java remote method invocation|RMI]] or [[RMI-IIOP]]), [[concurrency control]], [[dependency injection]] and [[access control]] for business objects. This package contains the Jakarta Enterprise Beans classes and interfaces that define the contracts between the enterprise bean and its clients and between the enterprise bean and the ejb container.
* [[Jakarta Persistence]] (''JPA'') are specifications about object-relational mapping between relation database tables and Java classes.
* [[Jakarta Transactions]] (''JTA'') contains the interfaces and annotations to interact with the transaction support offered by Jakarta EE. Even though this API abstracts from the really low-level details, the interfaces are also considered somewhat low-level and the average application developer in Jakarta EE is either assumed to be relying on transparent handling of transactions by the higher level EJB abstractions, or using the annotations provided by this API in combination with CDI managed beans.
* [[Jakarta Messaging]] (''JMS'') provides a common way for Java programs to create, send, receive and read an enterprise messaging system's messages.

=== Other specifications ===
* Jakarta Validation: This package contains the annotations and interfaces for the declarative validation support offered by the [[Jakarta Validation]] API. Jakarta Validation provides a unified way to provide constraints on beans (e.g. Jakarta Persistence model classes) that can be enforced cross-layer. In Jakarta EE, Jakarta Persistence honors bean validation constraints in the persistence layer, while [[JavaServer Faces|JSF]] does so in the view layer.
* Jakarta Batch provides the means for [[batch processing]] in applications to run long running background tasks that possibly involve a large volume of data and which may need to be periodically executed.
* [[Jakarta Connectors]] is a Java-based tool for connecting application servers and enterprise information systems (''EIS'') as part of enterprise application integration (''EAI''). This is a low-level API aimed at vendors that the average application developer typically does not come in contact with.

== Web profile ==
In an attempt to limit the footprint of web containers, both in physical and in conceptual terms, the web profile was created, a subset of the Jakarta EE specifications. The Jakarta EE web profile comprises the following:

== Certified referencing runtimes ==

Although by definition all Jakarta EE implementations provide the same base level of technologies (namely, the Jakarta EE spec and the associated APIs), they can differ considerably with respect to extra features (like [[Java EE Connector Architecture|connector]]s, [[Computer cluster|clustering]], [[Fault-tolerant design|fault tolerance]], [[high availability]], [[Computer security|security]], etc.), installed size, [[memory footprint]], startup time, etc.

==Code sample==

The code sample shown below demonstrates how various technologies in Java EE 7 are used together to build a web form for editing a user.

In Jakarta EE a (web) UI can be built using [[Jakarta Servlet]], [[Jakarta Server Pages]] (''JSP''), or [[Jakarta Faces]] (''JSF'') with [[Facelets]]. The example below uses Faces and [[Facelets]]. Not explicitly shown is that the input components use the Jakarta EE Bean Validation API under the covers to validate constraints.

<syntaxhighlight lang="xml">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:f="http://xmlns.jcp.org/jsf/core">

    <f:metadata>
        <f:viewParam name="user_id" value="#{userEdit.user}" converter="#{userConvertor}" />
    </f:metadata>

    <h:body>

        <h:messages />

        <h:form>
            <h:panelGrid columns="2">
                <h:outputLabel for="firstName" value="First name" />
                <h:inputText id="firstName" value="#{userEdit.user.firstName}" label="First name" />

                <h:outputLabel for="lastName" value="Last name" />
                <h:inputText id="lastName" value="#{userEdit.user.lastName}" label="Last name" />

                <h:commandButton action="#{userEdit.saveUser}" value="Save" />
            </h:panelGrid>
        </h:form>

    </h:body>
</html>
</syntaxhighlight>

===Example Backing Bean class ===

To assist the view, Jakarta EE uses a concept called a "Backing Bean". The example below uses [http://jcp.org/en/jsr/detail?id=299 Contexts and Dependency Injection (CDI)] and [[Jakarta Enterprise Beans]] (''EJB'').

<syntaxhighlight lang="java">
@Named
@ViewScoped
public class UserEdit {

    private User user;

    @Inject
    private UserDAO userDAO;

    public String saveUser() {
        userDAO.save(this.user);
        addFlashMessage("User " + this.user.getId() + " saved");

        return "users.xhtml?faces-redirect=true";
    }

    public void setUser(User user) {
        this.user = user;
    }

    public User getUser() {
        return user;
    }
}
</syntaxhighlight>

===Example Data Access Object class===

To implement business logic, [[Jakarta Enterprise Beans]] (''EJB'') is the dedicated technology in Jakarta EE. For the actual persistence, [[JDBC]] or [[Jakarta Persistence]] (JPA) can be used. The example below uses EJB and JPA. Not explicitly shown is that [[Java Transaction API|JTA]] is used under the covers by EJB to control transactional behavior.

<syntaxhighlight lang="java">
@Stateless
public class UserDAO {

    @PersistenceContext
    private EntityManager entityManager;

    public void save(User user) {
        entityManager.persist(user);
    }

    public void update(User user) {
        entityManager.merge(user);
    }

    public List<User> getAll() {
        return entityManager.createNamedQuery("User.getAll", User.class)
                            .getResultList();
    }

}
</syntaxhighlight>

===Example Entity class===

For defining entity/model classes Jakarta EE provides the Jakarta Persistence (''JPA''), and for expressing constraints on those entities it provides the Bean Validation API. The example below uses both these technologies.

<syntaxhighlight lang="java">
@Entity
public class User {

    @Id
    @GeneratedValue(strategy = IDENTITY)
    private Integer id;

    @Size(min = 2, message="First name too short")
    private String firstName;

    @Size(min = 2, message="Last name too short")
    private String lastName;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

}
</syntaxhighlight>
