Overview
In computing, Java Web Start (also known as JavaWS, javaws or JAWS) was a framework developed by Sun Microsystems (now Oracle) that allows users to start application software for the Java Platform directly from the Internet using a web browser. Some key benefits of this technology included seamless version updating for globally distributed applications and greater control of memory allocation to the Java virtual machine.
Functionality
Unlike Java applets, Web Start applications do not run inside the browser. By default they run in the same sandbox as applets, with several minor extensions like allowing to load and save the file that is explicitly selected by the user through the file selection dialog. Only signed applications can be configured to have additional permissions.
Web Start has an advantage over applets in that it overcomes many compatibility problems wit…
Deprecation
With JDK9, several deployment technologies including applets and Java Web Start were deprecated by Oracle.
In March 2018, Oracle announced it will not include Java Web Start in Java SE 11 (18.9 LTS) and later. Developers will need to transition to other deployment technologies. A few stand-alone alternatives have since arisen.
Implementation
The developer prepares a special XML file with JNLP extension. This file describes the application requirements, code location, parameters and additional permissions (if any). The browser downloads this file as any other and (following its MIME type, application/x-java-jnlp-file) opens it with Web Start tool. Web Start tool downloads all necessary resources and launches the appli…
Java Network Launching Protocol (JNLP)
Programmers often speak of the Java Network Launching Protocol (JNLP) interchangeably with the term "Web Start". The JNLP protocol, defined with an XML schema, specifies how to launch Java Web Start applications. JNLP consists of a set of rules defining how exactly to implement the launching mechanism. JNLP files include information such as the location of the jarpackage file and the name of the main class for the application, in addition to any other parameters for th…
Example
The example below gives a simple JNLP file to launch the applet, specifying code base, source, main class and window size. Such file contains all necessary references and is self-sufficient to launch the application. As no permissions are requested, the code will run in a sandbox. JNLP also states that this application can run offline (if already cached) and should be updated as a background process.
Pack200 compression
To reduce the size of a Java Web Start application Sun Microsystems introduced a compression system called Pack200 in Java 1.5.0. It can compress a large jar file to one-ninth of its original size if it contains only Java classes.
Java Web Start has supported Pack200 since it first appeared, but initially this feature required server-side cooperation and a certain amount of expertise to set up. When Sun introduced Java …
Signed Web Start applications
By default, Java Web Start applications run "restricted", which means that they do not have access to some system resources such as local files. But publishers can remove these restrictions by signing their Web Start applications with the jarsigner tool that comes with the JDK.
