DWR (Java)

The DWR project was started by Joe Walker in 2004, 1.0 released at 29 Aug 2005. DWR, or Direct Web Remoting, is a Java open source library that helps developers write web sites that include Ajax technology. It allows code in a web browser to use Java functions running on a web server as if those functions were within the browser.

It consists of two main parts:

DWR takes a novel approach to Ajax by dynamically generating JavaScript code based on Java classes. Thus the web developer can use Java code from JavaScript as if it were local to the web browser; whereas in reality the Java code runs in the web server and has full access to web server resources. For security reasons the web developer must configure exactly which Java classes are safe to export (which is often called web.xml or dwr.xml).

DWR is an acronym that could stand for:

Java

Java (Indonesian: Jawa; Javanese: ꦗꦮ) is an island of Indonesia. With a population of over 141 million (the island itself) or 145 million (the administrative region) as of 2015 Census released in December 2015, Java is home to 56.7 percent of the Indonesian population, and is the most populous island on Earth. The Indonesian capital city, Jakarta, is located on western Java. Much of Indonesian history took place on Java. It was the center of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally.

Formed mostly as the result of volcanic eruptions, Java is the 13th largest island in the world and the fifth largest in Indonesia. A chain of volcanic mountains forms an east–west spine along the island. Three main languages are spoken on the island, with Javanese being the dominant; it is the native language of about 60 million people in Indonesia, most of whom live on Java. Most residents are bilingual, with Indonesian as their first or second language. While the majority of the people of Java are Muslim, Java has a diverse mixture of religious beliefs, ethnicities, and cultures.

Java chicken

The Java is a breed of chicken originating in the United States. Despite the breed's name, which comes from the island of Java, it was developed in the U.S. from chickens of unknown Asian extraction. It is one of the oldest American chickens, forming the basis for many other breeds, but is critically endangered today. Javas are large birds with a sturdy appearance. They are hardy, and are well-suited for both meat and egg production, especially by small-scale farms, homesteads, and backyard keepers.

History

After the Dominique, the Java is the oldest breed of chicken created in the U.S. Though its name would suggest a Javan derivation, it is not known exactly where in Asia its ancestors came from. It was first mentioned in print in 1835, but it is thought to have been present well before this time. Javas were especially notable as meat production birds throughout the 19th century, with their popularity peaking in the latter half of that century.

The Java is a key foundation breed for the American class of chickens, having contributed significantly to major modern fowl such as the Jersey Giant, Rhode Island Red and Plymouth Rock. They are also likely to be the source of the yellow skin in contemporary Dominiques, which once had white skin.

Java (software platform)

Java is a set of computer software and specifications developed by Sun Microsystems, later acquired by Oracle Corporation, that provides a system for developing application software and deploying it in a cross-platform computing environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones to enterprise servers and supercomputers. While less common, Java applets run in secure, sandboxed environments to provide many features of native applications and can be embedded in HTML pages.

Writing in the Java programming language is the primary way to produce code that will be deployed as byte code in a Java Virtual Machine (JVM); byte code compilers are also available for other languages, including Ada, JavaScript, Python, and Ruby. In addition, several languages have been designed to run natively on the JVM, including Scala, Clojure and Groovy. Java syntax borrows heavily from C and C++, but object-oriented features are modeled after Smalltalk and Objective-C. Java eschews certain low-level constructs such as pointers and has a very simple memory model where every object is allocated on the heap and all variables of object types are references. Memory management is handled through integrated automatic garbage collection performed by the JVM.
