  • Java after IE?



    I understand [and welcome] that IE is going to go away.  but..   I need a java-capable browser.  I just tried edge and it doesn’t grok Java [and, of course, Firefox doesn’t].   Will I have to install yet-another browser _just_ for this one site I frequent that uses Java or is there something in win10 that can handle it

      _just_ for this one site I frequent

      Which site ?

    • #2396921

      it is an internal site local to my LAN – it is the “control panel” for our HVAC system.  It is virtually impossible to replace {where “replace” means big bucks}

      is it actually a Java app or is it just running JavaScript?

      If it’s JavaScript, all model browsers support that but it might be disabled in your Edge (visit the below link to check.)

        Is JavaScript enabled?

      If it’s an actual java app, you’ll need to download and install an older version of a browser, like Firefox 52.xx, that still included support for java apps

        Index of firefox releases

      Also, Java versions newer than JRE 8.xx no longer include the “browser plugin” required for java apps to work in a browser.

        Index of Java 8 releases

      Good luck!

      It is a real _java_ application — every time I go to mess with something in HVAC i get a “do you want to run this application” in order to open its control panel

      I have no idea what “JRE 8 xx” is.  I just got a Java update this morning [which is what got me wondering about it] and I checked its config [that didn’t seem to include a version #] and it says  “Java in the browser is enabled” and in the security tab I had to put the IP address of the controller as an allowed site.

      Use IE Mode within the new Edge. This is what MS is providing for legacy apps that require IE11 functionality:

      What is IE mode?
      IE mode on Microsoft Edge makes it easy to use all of the sites your organization needs in a single browser. It uses the integrated Chromium engine for modern sites, and it uses the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites.

      IE mode supports the following Internet Explorer functionality

      • All document modes and enterprise modes
      • ActiveX controls (such as Java or Silverlight).
      • Browser Helper Objects
      • Internet Explorer settings and group policies that affect security zone settings and Protected Mode
      • F12 developer tools for IE, when launched with IEChooser
      • Microsoft Edge extensions (Extensions that interact with the IE page content directly are not supported.)

      JRE stands for “Java Runtime Environment” which is the software used to “run” Java apps.

      JDK stands for “Java Development Kit” and, while it includes the JRE, it also contains the modules needed to actual “create” Java apps.

        To determine exactly which version you have installed, run java -version from a cmd prompt.

      The most current version of Java 8 (which still includes the browser plugin) is 1.8.0_311 which, as you noted, was just released yesterday.

        Note: Oracle “removed” the browser plugin starting with Java version 9 but that’s not really a problem if you’re already running version 8 as Java updates don’t cross “revision” boundaries (i.e. Java 8 will never update itself to Java 9, 9 to 10, 10 to 11, etc., etc.)

      So, why is 1.8.0_xxx called Java 8, 1.9.0_xxx Java 9, etc., etc.?

      No one knows for sure, but most users speculate it’s just a marketing ploy because progressing from Java 8 to 9, to 10, to 11, etc. sounds “much better” than going from Java 1.8 to 1.9, to 1.10, to 1.11, etc.

      Thanks for all the info.  As you’ve already mentioned, indeed:

      D:\>java -version
      java version “1.8.0_311”
      Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
      Java HotSpot(TM) Client VM (build 25.311-b11, mixed mode, sharing)

      Since I’ll be able to keep java 8 it circles around to my original question: when IE is gone, will edge or something allow java programs?

        Perhaps you missed #2396968 above?

      As NVtech777 pointed out, Edge has an IE mode that “should” allow you to open that site and run the Java app.

      To enable IE mode:

      1. Open Edge and enter edge://settings/defaultBrowser
      2. Change the “Allow sites to be reloaded in Internet Explorer mode” to Allow
      3. Click the Restart button for the change to take effect.

      After Edge restarts

      1. Open the site that requires Java.
      2. Click the settings dots.
      3. Scroll down to “Reload in Internet Explorer mode”
      4. You “should” get the prompt asking if you want to let the Java app run.

      I tried this with my own Edge (v93.0.961.38) and it worked perfectly (BTW, you’ll see an IE icon just to the left of a site’s URL while viewing it in IE mode.)

      You could then add the site to the list shown below the “Allow sites to be reloaded in Internet Explorer mode” option so it opens in IE mode each time you open it, but that list is only good for 30 days before you’d have to add it again.

      Since this seems like a situation where you’ll be visiting the site more often than that, a better option would be to enable “Enterprise Mode” and add it to an external “site list” file so Edge always opens it in IE mode.

      The above instructions make it seem like it’s difficult but, as long as you get the path to your site list set correctly, it’s actually very simple to just manually create the list (it’s a simple XML text file) and place it at the location you specified.

      Good luck!

      PERFECT!!   It worked wonderfully.  After I “allow”ed IE mode, I set the IP addr of the controller into “IE Pages” and it is even better than IE: no additional hassle or anything.  I tell it to go to the controller and it just pops right up with the login screen.  Wonderful.
