Java Platform, Enterprise Edition or Java EE is a widely used computing platform for enterprise software. J2EE provides an API and runtime environment for developing and running enterprise software, including network and web services, and other large-scale, multi-tiered, scalable, reliable, and secure network applications.
Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Applications compiled in Java code can run on all platforms that support Java without the need for recompilation.
The Java Native Interface (JNI) is a programming framework that enables Java code running in a Java Virtual Machine (JVM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
JavaServer Pages (JSP) is a nodenology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types. Released in 1999 by Sun Microsystems, JSP is similar to PHP and ASP, but it uses the Java programming language.
JTAG is a standard designed to assist with device, board, and system testing, diagnosis, and fault isolation. JTAG is used as the primary means of accessing sub-blocks of integrated circuits, making it an essential mechanism for debugging embedded systems which may not have any other debug-capable communications channel.
