Application program interface (API) specification for connecting programs written in Java to the data in popular databases. Defines how a client may access a database JDBC. Contains set of interfaces and these interfaces are implemented by various database vendors and server vendors.


A small Java library. Used for implementing asynchronous topology without writing boilerplate code.


Free integrated development environment that simplifies the development of Java-based applications addressing every step of the application lifecycle. It offers features for development in Java, XML, SQL and PL/SQL, HTML, JavaScript, BPEL and PHP.


A set of tools and libraries that are needed to compile and run a Java program. Includes the Java Runtime Environment, the Java compiler and the Java APIs. JDK is an implementation of either of Java SE, Java EE or Java ME.


An open source, production quality framework for developing RESTful web services in Java that provides support for JAX-RS APIs and serves as a JAX-RS Reference Implementation. Provides its own API that extends the JAX-RS toolkit with additional features and utilities to further simplify RESTful service and client development. 


A pure Java-based HTTP (Web) server and Java Servlet container. Jetty is often used for machine to machine communications, usually within larger software frameworks. It can be easily embedded in devices, tools, frameworks, application servers, and clusters.


A lexical analyzer generator (also known as scanner generator) for Java, written in Java. A lexical analyzer generator takes as input a specification with a set of regular expressions and corresponding actions.


Tool for collecting diagnostic and profiling data about a running Java application. It is integrated into the Java Virtual Machine (JVM) and causes almost no performance overhead, so it can be used even in heavily loaded production environments.


Advanced set of tools that enables efficient and detailed analysis of the extensive of data collected by Java Flight Recorder. The tool chain enables developers and administrators to collect and analyze data from Java applications running locally or deployed in production environments.


The Java memory model specifies how the Java virtual machine works with the computer's memory (RAM). The Java virtual machine is a model of a whole computer so this model naturally includes a memory model - AKA the Java memory model. language.


Library that supports test-driven development of Java code with mock objects. Mock objects help design and test the interactions between the objects in your programs. JMock focuses on explicitly specifying the behavior of the mocks using a specialized DSL (Domain-Specific Language) embeded in the Java code.


Java API that allows applications to create, send, receive, and read messages. The JMS API defines a common set of interfaces and associated semantics that allow programs written in the Java programming language to communicate with other messaging implementations.



Technology for application in the J2EE environment. With JMX, you will be able to monitor and manage your Java applications. JMX’ monitoring capabilities include looking at attributes and components running inside the Java Virtual Machine environment.


A Java programming interface, or API, that allows developers to access the languages of a host system and determine the way Java integrates with native code.


Java Persistence API to connect database into your Java application. JPA allows to flexibly change the underlying ORM framework. The Java Persistence API provides Java developers with an object/relational mapping facility for managing relational data in Java applications.


Stands for Java Persistence Query Language, a platform-independent object-oriented query language defined as part of the JPA specification, allows you to define database queries based on entity model, it is based on SQL syntax, but it operates on objects, attributes and relationships instead of tables and columns. 


The Java Runtime Environment that consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. The Java Runtime Environment provides the minimum requirements for executing a Java application.


Server-side programming technology that enables the creation of dynamic, platform-independent method for building Web-based applications. Technology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types.


Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods.


Technology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types. A JSP is translated into Java servlet before being run, and it processes HTTP requests and generates responses like any servlet.


Collection of useful JSP tags which encapsulates core functionality common to many JSP applications. JSTL has support for common, structural tasks such as iteration and conditionals, tags for manipulating XML documents, internationalization tags, and SQL tags.


Simple framework to write repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks. JUnit features include: assertions for testing expected results, test features for sharing common test data, test suites for easily organizing and running tests, graphical and textual test runners.


An abstract computing machine that enables a computer to run a Java program. There are three notions of the JVM: specification, implementation, and instance. JVM mimics a real Java processor, enabling Java bytecode to be executed as actions or operating system calls on any processor regardless of the operating system.


Refers to three things, depending on the context. A keystore can be a repository where private keys, certificates and symmetric keys can be stored. This is typically a file, but the storage can also be handled in different ways, e.g. cryptographic token or using the OS's own mechanism.


Statically typed programming language for modern multiplatform applications. 100% interoperable with Java and Android, compiles to Java 6 byte code, runs everywhere Java runs from servers to Android, and uses existing Java tools for its package management and build system.
