'''Java Web Start''' is a framework developed by [[Sun Microsystems]] that enables starting [[Java programming language|Java]] [[application]]s directly from the [[World Wide Web|Web]] using a [[Web browser|browser]]. Unlike [[Java applet]]s, Web Start applications do not run inside the browser, and the [[Sandbox (computer security)|sandbox]] in which they run does not have to be as restricted, although this can be configured. One chief advantage of Web Start over applets is that they overcome many compatibility problems with browsers' Java [[plugin]]s and different [[Java virtual machine|JVM]] versions. On the other hand, Web Start programs cannot communicate with the browser as easily as applets. To assist migration, a Java Applet can also be used as a Java Web Start application.

Web Start also provides a series of classes in the <code>[http://java.sun.com/products/javawebstart/docs/javadoc/index.html javax.jnlp]</code> [[PackagesJava in Javapackage|package]] which provide various services to the application. Most of these services are designed around the idea of allowing carefully controlled access to resources (such as files and the system clipboard) while restricting the application to authorized operations.

Version 1.0 of Web Start was introduced by Sun in March [[2001]]{{ref|pr}}, and ever since [[Java 2 Platform, Standard Edition|J2SE]] version 1.4 it has been included by default with the [[Java Runtime Environment]] (JRE) and does not have to be installed separately.
