Difference between java and apple java3/27/2023 The JNLP file is created by the application developer and hosted on any Web server. JNLP is not a network protocol (all Web Start traffic is through standard HTTP) it’s an XML DTD that provides the necessary information for Web Start to launch an application. Users with Web Start installed are able to launch Java applications from remote or local locations by navigating to URLs that end with the Java Network Launching Protocol (jnlp) extension. The installation process is simple, and in part three of this series we’ll see how to make it automatic in some cases. The Web Start end-user application, which is available for a multitude of platforms, can be found on Sun’s Web site. What’s more, Web Start seamlessly handles updated applications without any user intervention. After they’ve done so, they’re able to run any Java application packaged for Web Start execution without any further installation hassles. Recognizing this problem, Sun created Java Web Start, which users need to install on their systems only once. Many third-party tools are available to simplify Java application installation and updating, but most are expensive and all greatly restrict the user’s choice of platforms. Releasing new versions of installed applications is also problematic. Java promotes itself as a “write once, run anywhere” language, but application installation requires more operating system interaction than Java’s lowest common denominator can provide. Of course, applications have their own drawbacks, most notably their difficulty of installation. Server-side developers and devotees of Sun’s Swing can tap a wide range of IDEs and the support of a strong Java community. On the other hand, Java applications have only grown in popularity. Sun’s Java plug-in does a lot to address the later issue, but applets still have a declining fan base. However, a necessary yet limiting sandbox model and spotty browser support have led to a decline in Java applets’ popularity. Applet creators need only replace the class files or jars on their Web servers, and users get the newer version the next time they run the applet. The ease of updating applets is one of their most compelling benefits. This advance offers a nice compromise between the ease of distribution provided by Java applets and the power of Java applications.Īpplets run in the Web browser and require no installation. Sun’s Java Web Start makes installing Java applications as simple as tagging Web links to check and access centralized resources files. Find out how Web Start works and how you can roll it out. ![]() Sun's Web Start offers an easy way to deploy Java applications by adapting the best traits of applets and applications.
