Launching Web Start applications

Guest Author

Java applications can be distributed to clients through download capabilities like Applet and Web Start. These applications are delivered to users through web browsers, allowing for convenient access on client systems.

Web Start applications can be launched from any web browser by opening the application’s JNLP file. Once opened, these applications no longer rely on browser plugins or integrations. Instructions for launching JNLP files can be located in "What is Java Web Start and how is it launched" on Java.com. In short, this involves associating the .jnlp file association with Java’s javaws command.

Desktop Administrators can control Web Start dialogs/prompts by using Deployment Rule Sets (DRS). This DRS feature enabled administrators to create an application whitelist that can control execution of known-safe applications as well as manage compatibility between different versions of Java on the same system.

System Administrators can use the Java Advanced Management Console to track Java usage within their organization, identifying Applet, Web Start, and other Java application types. This usage tracking enables them to identify which versions of Java are used by which applications, and create Deployment Rule Sets to manage compatibility between versions.

    Why is oracle not supporting PPAPI? We and others feel that java is not an option for web development. investments made in Java / Applets are lost as a consequence of the lack of support for modern standards such PPAPI.

    I wish to load the latest JAVA version as I make use of the CHARTS on the Forex programme. Please send me a link to click on to load the latest version.

  • guest Friday, September 4, 2015

  • Angela Yargus-Carter Friday, September 4, 2015

    I have been a member for a long time, and I find it exasperating that I can't just play my games which I enjoy so much on POGO. I am 80, and really miss the simplicity that POGO offers. Can we find a way to play on either Explorer or Chrome?

  • costlow Friday, September 4, 2015

    There are some details about POGO at http://www.java.com/en/download/help/pogo.xml or http://help.ea.com/article/java-help-and-information or http://help.ea.com/en/pogo/pogo/

    For installation issues or to obtain the latest version of Java, visit https://java.com

    Been playing at IWON.Com for almost 20 years and Google decides to not let Java work anymore sounds like Profit move with others and have the old school computer people suffer because of it. I'm 73 and been around computers since 1962. please advise how to get IWON.COM working on my computer.

  • Regina Feldman Sunday, September 6, 2015

  • guest Monday, September 7, 2015

    Anyone here using Adito Agent Java plugin? I would appreciate suggestions how to make it work in lastest version of Chrome or laternatively a link to any PPAPI equivalent. Thanks

  • guest Monday, September 7, 2015

    Since yesterday I cannot use Java anymore in Google Chrome? How can I fix this? This is just annoying, I don't want to need another browser just to be able to use Java. Simple instructions please, English isn't my native tongue.

  • Ajay Sharma Thursday, September 10, 2015

    Is there any solution for the NPAPI plugins to work on Google chrome 45 version?

  • costlow Friday, September 11, 2015
  • guest Monday, September 14, 2015

    @costlow did you read the link you give ?? it tells to come on this thread for a solution...

    Developers and System administrators looking for alternative ways to support users of Chrome should see this blog regarding Launching Web Start applications.

    but thanks for your help.......... (sic)

  • costlow Monday, September 14, 2015

    I thought that was a question about being a user. For a developer working on an application, the following link should help: http://docs.oracle.com/javase/8/docs/technotes/guides/deploy/applet_dev_guide.html#JSDPG1032

  • B&ugrave;i V&#259;n Duy Tuesday, September 15, 2015

  • Mildred L Craig Wednesday, September 16, 2015

    Google Chrome doesn't allow this version of Java.

  • guest Friday, September 18, 2015

    why is it necessary to do this and inconvenience millions of people - why not make JVa compatible with Google?

  • guestbigpop727 Friday, September 18, 2015

    I'm running internet explorer with updated new java on brand new windows 10..i thnk I need to disable the plug in.. how doi do that....

  • guest Wednesday, September 23, 2015

    ORACLE, Please write a * PPAPI * plugin, or get the open-source community to do it for you. This MUST be done, going forward.

  • guest Thursday, September 24, 2015

    this is making me angry because it wont let me on it keeps saying that Google chome does not support it

  • jenny Friday, September 25, 2015

    Like Canon drops own customers with LBP800,810,..,1120,... Google steps the same way.

    From the Oracle site: "... Oracle recommends using Firefox, Internet Explorer or Safari instead".

    "OK Google" <pause> Uninstall Chrome <pause> Goodbye.

  • guest Saturday, September 26, 2015

    Bye Bye Chrome!

  • guest Tuesday, September 29, 2015

    there's a solution given by oracle to enable napi on chrome 45, but for a reason I can't guess out, it only worked after many reboots ; maybe KIS 2015 was involved, I'm not sure ; now under KIS 2016 and it still works...

  • eafefsf Friday, April 28, 2017
    When this blog was originally posted the change was
    scheduled to occur with the January 2017 Critical Patch Update. In response
    to requests for additional time to prepare for this change Oracle now
    plans to deliver this change with the April 2017 Critical Patch Update.
    The blog has been updated accordingly.
  • sandra lauw Friday, April 28, 2017

  • Tom Coon Saturday, May 6, 2017
    Every Tom, Dick and Harry wants to be a program engineer. Design engineers like politicians (attorneys ), just keep finding more and more ways to make themselves and there services needed. As a middle aged business owner that started using computers before windows and built computers in the mid 1990's AND today own AND operate mac"s AND pc's AND ipads AND iphones (about 20 units total ) , FIND WE SPEND MORE TIME TRYING TO KEEP EVERYTHING WORKING THAN ANY OTHER TOOL OR EQUIPMENT THAT WE OWN OR RENT.
    Why is this ??
    What did we do to be treated like this ??
    We have paid our dues ???
    How many different platforms, languages, or whatever you want to call it , DO WE REALLY NEED ?????
    Please get on the same page, lets all get along !!
    THINK ABOUT THIS, if we are spending all of our time (there is only 2080 work hours in a year) fixing, downloading, updating, tech supporting ( I LOVE THOSE GUYS AND WHAT THEY HAVE TO DEAL WITH EVERYDAY ), on the phone AND so on ---------- WHO IS ACTUALLY DOING WORK TO BE PRODUCTIVE ??????

    hi my chrome browser is showing this error while verifying java

    The Chrome browser does not support NPAPI plug-ins and therefore will not run all Java content. Switch to a different browser (Internet Explorer or Safari on Mac) to run the Java plug-in.

  • john wiggins Friday, November 30, 2018
    This is crazy. So many important apps depend on java, now Firefox is non supporting. Do we have to find an alternative? What is the alternative for charts applets ???
