Web Start Java Archive
There are currently three older Java Web Start releases available for download: The Java Web Start 1.4.2 is delivered as part of the version Java 2 Platform, Standard Edition 1.4.2. The Java Web Start 1.2 is delivered as part of the Java 2 Platform, Standard Edition 1.4.1 (J2SE 1.4.1). Web Start 1.0.1, is available as a seperate file and can be downloaded here.
it is not supplied as part of the J2SE platforms. The Java Web Start 1.4.2 is now available. This is installed with BAE 1.4.2 of JRE/SDK. Refer to the following related documentation: Web Start Java 1.2 is distributed as part of the Java 2 Platforms, Standard Edition, v. 1.4.1 (J2SE 1.4.1).
Also see the following Java Web Start 1.2 manual. Java Web Start 1.0.1 already published is still available for separate downloading (not part of a J2SE platforms version). Also see the following Java Web Start 1.0.1 manual.

Java Web Start (also known as JAWS ) is a Java Web Start platform designed by Sun Microsystems (now Oracle) that allows a user to launch Java platform Java apps directly from the Web using a Web browsers. The main advantages of this wireless solution provide a smooth update for global deployments and better management of storage allocations to the Java VM.
Oracle has classified Java Web Start as obsolete and it will be deleted in Java SE 11. In contrast to Java Applets, Web start requests do not run in the Web Browser. They run by default in the same sandpit as an applet, with several smaller enhancements such as loading and saving the files manually chosen by the users via the files chooser.
You can configure only autographed apps to have extra privileges. Compared to the applet, Web Start has the benefit that it solves many issues of compatiblity with the Java plug-ins of the browser and different Java VMs. The Web Start program is no longer an integral part of the website, it is an application that runs in a standalone framework.
You can also start Web Start with unchanged Applets packed in.jar archives by typing the appropriate JNLP for them. You can also specify the parameter of the appelet. You can also run such appelets in a seperate window. Just like appelets, Java Web Start is cross-platform. Also in March 2018, Oracle proclaimed that it will not contain Java Web Start in Java SE 11 (18. 9 LTS) and later in March 2018.
Development engineer creates a specific class syntax filename with enhancement YNLP. Contains the details of the applications required, the source location, parameter and extra privileges (if any). Like any other download, the web browsers download this and open it (according to its method, i. e. according to its method of access, application/x-java-jnlp-file) with the Web Start utility. The Web Start utility will download all necessary ressources and start the game.
javac Web Start offers a number of class types in the Java Web Start Java Web Start Bundle that offer various service packages for the Java Web Start applications. Most of these Sun has developed with the goal of providing meticulously managed resource accessibility (such as file and system clipboard) while limiting the usage to authorised use.
In March 2001, Sun released Web Start 1.0 v1.0, while 64-bit Windows was only added in Java 6 (later than 64-bit Java was first available). Because J2SE 1. 4 Web Start ships as the standard part of the Java Runtime Environment (JRE) with the name JavaWaws, computer admins no longer need to reinstall it later.
Key Web Start functionality includes the option to autodelete and deploy a JRE if the end users do not have Java enabled, and the option for developers to specify which JRE release a particular application needs to run. Users do not need to stay online to run the downloads as they are executed from a local maintain queue.
Web downloaded updates become available when the users are connected to the Web, making it easier to deploy. Every computer can use JNLP by just installs a JNLPlient ( usually Java Web Start ). It can be installed automagically so that the end users can see how the Java app downloads and installs the Java app the first time the app is run by the Java Server Manager.
The JNLP works similar to HTTP/HTML for the web. To display an HTML web page, after clicking on a web link, the web server sends a web server a web link containing a HTML reply message. It then queries the resource to which the page refers (images, css) and eventually returns the page as soon as it has enough information.
As a rule, page rendering begins before all resource downloads; some resource that are not crucial to the page design (e.g. images) can be continued afterwards. The JNLP reflects this behavior; just as a web page is rendered by a web page by a web page renderer, a JNLP server "renders" a Javaapp. Once the visitor has clicked on a web link, the web browser sends a web server a web address that responds with a JNLP instead of HTML format response files for the use.
JNLP analyzes this filename, prompts for the specified resource (jar file), awaits fetching all needed resource, and then starts the app. JNLP filename can cause resource listing to be "lazy", informing the JNLP clients that the app does not need these resource to start, but can get them later when the app asks for them.
This example shows a JNLP executable for starting the applelet with the following information: basic data, sourcecode, major classes and windowsize. Contains all necessary reference files and is enough to start the program. Also JNLP means that this app can run off-line (if it is already cached) and should be upgraded as a batch operation.
Main " "300" "200" "Background" Java Web Start has been supporting Pack200 since its first release, but first of all this function demanded server-side collaboration and a certain amount of knowledge. With Sun's introduction of Java SE 6u10, package200 without specific host connectivity became available. Applications designer can activate or deactivate this function in JNLPs.
Pack200 increases the start speed and downloading speed for low-speed connectivity. Java Web Start apps run "restricted" by default, which means that they do not have full control over some system assets such as locale file types. However, a publisher can overcome these limitations by using the Web Start authoring utility included with the JDK to sign their Web Start apps.
