Jakarta Connectors ( JCA ; formerly known as Java EE Connector Architecture and J2EE Connector Architecture ) are a set of Java programming language tools designed for connecting application servers and enterprise information systems (EIS) as a part of enterprise application integration (EAI). While JDBC is specifically used to establish connections between Java applications and databases, JCA provides a more versatile architecture for connecting to legacy systems.
21-480: JCA was developed through the Java Community Process, with versions including JSR 16 (JCA 1.0), JSR 112 (JCA 1.5), and JSR 322 (JCA 1.6). J2EE Version 1.3 requires application servers to support JCA Version 1.0. J2EE Version 1.4 requires application servers to support JCA Version 1.5. Java EE Version 6 requires application servers to support JCA version 1.6. The Jakarta Connector Architecture defines
42-557: A "Backing Bean". The example below uses Contexts and Dependency Injection (CDI) and Jakarta Enterprise Beans ( EJB ). 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 JTA is used under the covers by EJB to control transactional behavior. For defining entity/model classes Jakarta EE provides
63-503: A "Project Management Committee" in the bylaws ), some of which have a number of sub-projects. Unlike some other organizations that host FOSS projects, before a project is hosted at Apache it has to be licensed to the ASF with a grant or contributor agreement. In this way, the ASF gains the necessary intellectual property rights for the development and distribution of all its projects. The Board of Directors of The Apache Software Foundation (ASF)
84-399: A collaborative, consensus-based development process and an open and pragmatic software license, which is to say that it allows developers, who receive the software freely, to redistribute it under non-free terms. Each project is managed by a self-selected team of technical experts who are active contributors to the project. The ASF is a meritocracy , implying that membership of the foundation
105-399: A database in a transactional way, managing distributed queues. The Jakarta EE APIs include several technologies that extend the functionality of the base Java SE APIs , such as Jakarta Enterprise Beans , connectors , servlets , Jakarta Server Pages and several web service technologies. In an attempt to limit the footprint of web containers, both in physical and in conceptual terms,
126-618: A number of open-source software projects. The ASF was formed from a group of developers of the Apache HTTP Server , and incorporated on March 25, 1999. As of 2021, it includes approximately 1000 members. The Apache Software Foundation is a decentralized open source community of developers. The software they produce is distributed under the terms of the Apache License , a permissive open-source license for free and open-source software (FOSS). The Apache projects are characterized by
147-524: A series of additional meetings to elect board members and resolve other legal matters regarding incorporation, the effective incorporation date of the Apache Software Foundation was set to June 1, 1999. Co-founder Brian Behlendorf states how the name 'Apache' was chosen: "I suggested the name Apache partly because the web technologies at the time that were launching were being called cyber this or spider that or something on those themes and I
168-629: A standard for connecting a compliant application server to an EIS. It defines a standard set of system-level contracts between the Jakarta EE application server and a resource adapter. The system contracts defined by Version 1.0 of the J2EE Connector Architecture are described by the specification as follows: Transaction management enables an application server to use a transaction manager to manage transactions across multiple resource managers. This contract also supports transactions that are managed internal to an EIS resource manager without
189-475: 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. To assist the view, Jakarta EE uses a concept called
210-565: Is granted only to volunteers who have actively contributed to Apache projects. The ASF is considered a second-generation open-source organization, in that commercial support is provided without the risk of platform lock-in . Among the ASF's objectives are: to provide legal protection to volunteers working on Apache projects, and to prevent the "Apache" brand name from being used by other organizations without permission. The ASF also holds several ApacheCon conferences each year, highlighting Apache projects and related technology. The history of
231-512: Is responsible for management and oversight of the business and affairs of the corporation in accordance with the Bylaws. This includes management of the corporate assets (funds, intellectual property, trademarks, and support equipment), appointment of a President and corporate officers managing the core operations of the ASF, and allocation of corporate resources for the benefit of Apache projects. Technical decision-making authority for every Apache project

Fielding , Dean Gaudet, Ben Hyde, Jim Jagielski , Alexei Kosut, Martin Kraemer, Ben Laurie , Doug MacEachern, Aram Mirzadeh, Sameer Parekh , Cliff Skolnick, Marc Slemko, William (Bill) Stoddard, Paul Sutton, Randy Terbush and Dirk-Willem van Gulik . After
273-629: The Apache Software Foundation is linked to the Apache HTTP Server, development beginning in February 1993. A group of eight developers started working on enhancing the NCSA HTTPd daemon . They came to be known as the Apache Group. On March 25, 1999, the Apache Software Foundation was formed. The first official meeting of the Apache Software Foundation was held on April 13, 1999. The initial members of
294-708: The JDB API. Great Plains Systems provides an interface called eConnect to integrate with other platforms. SAP provides an interface for Java called SAP Java Connector (SAP JCo). J2EE Jakarta EE , formerly Java Platform, Enterprise Edition ( Java EE ) and Java 2 Platform, Enterprise Edition ( J2EE ), is a set of specifications, extending Java SE with specifications for enterprise features such as distributed computing and web services . Jakarta EE applications are run on reference runtimes , which can be microservices or application servers , which handle transactions, security, scalability, concurrency and management of
315-587: The Jakarta Persistence ( JPA ), and for expressing constraints on those entities it provides the Bean Validation API. The example below uses both these technologies. Apache Software Foundation The Apache Software Foundation ( / ə ˈ p æ tʃ i / ə- PATCH -ee ; ASF ) is an American nonprofit corporation (classified as a 501(c)(3) organization in the United States) to support
336-499: The components they are deploying. Jakarta EE is defined by its specification . The specification defines APIs (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 systems . The platform
357-522: The necessity of involving an external transaction manager. JCA Version 1.5 adds system contracts to the specification as follows: JCA adapters can be built to integrate with various Enterprise Information System such as Siebel Systems , SAP AG , Great Plains Systems , Oracle Applications , etc. Siebel provides API to integrate with various platforms like Java , C++ , .NET , Visual Basic , etc. For Java it provides an interface called ' Java Data Bean ' (JDB). The Siebel adapter provides data access via
378-609: The use of javax and Java trademarks. Oracle owns the trademark for the name "Java" and the platform was renamed from Java EE to Jakarta EE. The name refers to the largest city on the island of Java and also the capital of Indonesia, Jakarta . 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 . Jakarta EE includes several specifications that serve different purposes, like generating web pages, reading and writing from
399-644: The web profile was created, a subset of the Jakarta EE specifications. The Jakarta EE web profile comprises the following: 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 connectors , clustering , fault tolerance , high availability , security , etc.), installed size, memory footprint , startup time, etc. The code sample shown below demonstrates how various technologies in Java EE 7 are used together to build
420-621: 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. Java EE was maintained by Oracle under the Java Community Process . On September 12, 2017, Oracle Corporation announced that it would submit Java EE to the Eclipse Foundation . The Eclipse top-level project has been named Eclipse Enterprise for Java (EE4J). The Eclipse Foundation could not agree with Oracle over
441-779: Was like we need something a little more interesting, a little more romantic, not to be a cultural appropriator or anything like that, I had just seen a documentary about Geronimo and the last days of a Native American tribe called the Apaches right, who succumbed to the invasion from the West, from the United States, and they were the last tribe to give up their territory and for me that almost romantically represented what I felt we were doing with this web-server project..." Apache divides its software development activities into separate semi-autonomous areas called "top-level projects" (formally known as
