Jakarta Enterprise Beans is one of several Java APIs for modular construction of enterprise software. EJB is a server-side software component that encapsulates business logic of an application. An EJB web container provides a runtime environment for web related software components, including computer security, Java servlet lifecycle management, transaction processing, and other web services. The EJB specification is a subset of the Java EE specification.
The Jakarta Transactions, one of the Jakarta EE APIs, enables distributed transactions to be done across multiple X/Open XA resources in a Java environment. JTA was a specification developed under the Java Community Process as JSR 907. JTA provides for:
The Jakarta Messaging API is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem, that can be used to facilitate the sending and receiving of messages between software systems. Jakarta Messaging is a part of Jakarta EE and was originally defined by a specification developed at Sun Microsystems before being guided by the Java Community Process.
Jakarta EE, formerly Java Platform, Enterprise Edition 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, that can be microservices or application servers, which handle transactions, security, scalability, concurrency and management of the components it is deploying.
The Java programming language XML APIs developed by Sun Microsystems consist of the following separate computer-programming APIs:
In computing, the Java API for XML Processing, or JAXP, one of the Java XML Application programming interfaces, provides the capability of validating and parsing XML documents. It has three basic parsing interfaces:
Java Management Extensions (JMX) is a Java technology that supplies tools for managing and monitoring applications, system objects, devices and service-oriented networks. Those resources are represented by objects called MBeans. In the API, classes can be dynamically loaded and instantiated. Managing and monitoring applications can be designed and developed using the Java Dynamic Management Kit.
In software engineering, service-oriented architecture (SOA) is an architectural style that supports service orientation. By consequence, it is as well applied in the field of software design where services are provided to the other components by application components, through a communication protocol over a network. A service is a discrete unit of functionality that can be accessed remotely and acted upon and updated independently, such as retrieving a credit card statement online. SOA is also intended to be independent of vendors, products and technologies.
Jakarta Connectors is a Java programming language tool for connecting application servers and enterprise information systems (EIS) as part of enterprise application integration (EAI). While JDBC is specifically used to connect Java applications to databases, JCA is a more generic architecture for connection to legacy systems. JCA was developed under the Java Community Process as JSR 16, JSR 112 and JSR 322.
GNOME-DB is a database application by the GNOME community. The project aims to provide a free unified data access architecture to the GNOME project for all Unix platforms. GNOME-DB is useful for any application that accesses persistent data, since it now contains a data management API.
The Web Services Invocation Framework (WSIF) supports a simple and flexible Java API for invoking any Web Services Description Language (WSDL)-described service.
Web Services Discovery provides access to software systems over the Internet using standard protocols. In the most basic scenario there is a Web Service Provider that publishes a service and a Web Service Consumer that uses this service. Web Service Discovery is the process of finding suitable web services for a given task.
Hibernate ORM is an object–relational mapping tool for the Java programming language. It provides a framework for mapping an object-oriented domain model to a relational database. Hibernate handles object–relational impedance mismatch problems by replacing direct, persistent database accesses with high-level object handling functions.
In computing, Web-Based Enterprise Management (WBEM) comprises a set of systems-management technologies developed to unify the management of distributed computing environments. The WBEM initiative, initially sponsored in 1996 by BMC Software, Cisco Systems, Compaq Computer, Intel, and Microsoft, is now widely adopted. WBEM is based on Internet standards and Distributed Management Task Force (DMTF) open standards:
The Jakarta Standard Tag Library is a component of the Java EE Web application development platform. It extends the JSP specification by adding a tag library of JSP tags for common tasks, such as XML data processing, conditional execution, database access, loops and internationalization.
Content Repository API for Java (JCR) is a specification for a Java platform application programming interface (API) to access content repositories in a uniform manner. The content repositories are used in content management systems to keep the content data and also the metadata used in content management systems (CMS) such as versioning metadata. The specification was developed under the Java Community Process as JSR-170, and as JSR-283. The main Java package is javax.jcr.
Jakarta Persistence is a Jakarta EE application programming interface specification that describes the management of relational data in enterprise Java applications.
Jakarta RESTful Web Services, is a Jakarta EE API specification that provides support in creating web services according to the Representational State Transfer (REST) architectural pattern. JAX-RS uses annotations, introduced in Java SE 5, to simplify the development and deployment of web service clients and endpoints.
Jakarta Management is a Java specification request (JSR-77) for standardization of Jakarta EE server management. Jakarta Management abstracts the manageable parts of the Jakarta EE architecture and defines an interface for accessing management information. This helps system administrators integrate Jakarta EE servers into a system management environment and also helps application developers create their own management tools from scratch.
