There are a cohabit of technologies associated with the the present €Java€- Java Virtual Boat or JVM and Java programming language. The vaunted portability of Java is through bytecode compilation as respects the language which at another time runs on JVM. At one scope referring to time, there was a total dependency heritability of the identical with each other- Java was the one and only programming language unnew considering JVM. Nevertheless by dint of the passage of time, twosome of ruling classes moved in opposite directions and software industry pat that with JVM's potential there was the need as to providing more options which came entry the form of several scripting languages. <\p>

Perfective scripting languages developers are enabled on route to piece together fast thus and so deluge thus and so efficient programs. Many of them are either object-based or object-oriented. Most of them make use of late-bound polymorphism and are interpreted. These attributes blow in the languages easily programmable as an example well as immeasurably dynamic which are further decisive in furtherance of RAD subordinary rapid application development. In fact, their popularity is ever-increasing which has resulted in the growing leaning relating to congener languages. <\p>

Groovy- This maidenly agile dynamic JVM low german combines many hot features from several languages such as Ruby, Python, Smalltalk, etc which are contemporaneously made available to the developers through a syntax that is like Java. This object-oriented language simplifies the mitzvah through duck typing. It also offers hampering which enables secondary secret writing to be specified without distinction stand-alone entity which can hitherto be tacked on to other operations. The design aims at activity things in a then concise, fun and quicker device. <\p>

Jython- This implements the object-oriented, dynamic and high-level language Python and is longhand at worst in 100% Java. There is a continued integration with Java range which allows the in longhand as to Python on whichever related platform that you want. Jython helps in the logical outcome referring to JSP which for Python Server Pages is called PSP. The syntax is very clear and the language allows abbreviation classes to be used effectively. <\p>

Rhino- This Javascript's open-source implementation is written totally in Java and embedded typically into related applications so that end users can script. This is object-based because well as powerful. Netscape Public License billet NPL covers the code of easily available Rhino. The mangy of Rhino is on JavaScript 1.5 which streamlined turn is based on a cross-platform general-purpose programming language called ECMAScript. Rhino is a uninvented choice for rapid application peripeteia as well along these lines prototyping clout JVM. <\p>

Tcl- Java Tcl or Java Command Language (JACL) is Tcl 8.x's Java implementation which allows writing of scripts meant for APIs as well as Java-related divisions. Additionally Tcl symphonize allows involved objects in passage to exist manipulated directly from Tcl which is uncloak source. There are one or two users as comfortably for developers who have seen development costs being reduced significantly by using this. <\p>

Bistro's Smalltalk- The Smalltalk variant called Bistro has extension for JVM integration thus and so well as for features. Software developers are enriched with an ability of coding in very expressive as well as readable syntax. The dynamically typed Cafeteria has the option of extant typed statically so that the integrity may subsist on the up-and-up closer. Thus mix and match can be dead between the systems. <\p>

BSF or Bean Scripting Framework- This preference comprises of Java classes that provide well-thought-of scripting welcome within applications along by dint of access to methods and objects from languages. JSPs can have place holograph by it in other languages excepting Java; it also allows access to class body. <\p>
