JRE Version

I realize that TenFourFox contains its own java script engine and thus doesn't need the OSX java engine. However there are many sites which are Java based and require a java response of 1.6 or higher to operate. An example is Karl Jeakle's Mortgage Calculator. When I go to Browser Hawk using 10/4 it states that my java is 1.5 which is what OSX thinks. It would be helpful if I could select the value of that variable. The BrowserHawk link is:

    Dennis, JavaScript and Java are two different things. TenFourFox does include its own advanced JavaScript interpreter and compiler, which we maintain. However, JavaScript cannot run Java applets. Apple has never supported Java 1.6 for any Power Mac under any version of OS X; even in 10.5, only Java 1.5 is supported, and TenFourFox will not run Java applets for security reasons due to several known cross-platform exploits in Java 1.5.

    You may be able to install a version of the OpenJDK, but you would need to use a different browser to enable the plugin, since TenFourFox has not supported plugins since version 6. Unfortunately, we can't offer support for that here, and I'm not sure if any version of OpenJDK will work with 10.4.

    I have installed OpenJDK but when online and remotely queried, the browser reports 1.5 preventing operation with sites requiring 1.6.

    You'd have to look at how the Java plugin is configured. I can't advise on that, since we don't support it.

    Cameron, if you goto:
    you will see that it reports your java script engine as ver. 1.5
    That is my problem. I am a neophyte but that response must pass through your browser from OSX. It shouldn't.

    JavaScript in 17.x is actually version 1.8.6 (and again, has nothing to do with the Java version). See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/A... and http://www.htmlgoodies.com/beyond/javascript/article.php/3470971/Ja... for more information on the version differences. TenFourFox 17.x is equivalent to Gecko 17.

    BrowserHawk should not be able to detect Java (again, NOT JavaScript) at all. If it does, you have plugins enabled, and are using the browser in an unsupported configuration. That said: 1.5 is indeed the version of Java that comes with 10.4 and 10.5. The Java plugin is what actually runs within the browser and it is configured to use the system JRE, not OpenJDK. The plugin may not be aware that you have OpenJDK installed, and you will need to alter the plugin's settings or certain components on your system to use OpenJDK instead of Java 1.5. Again, that's something I can't help you with here.

    I assume that the Mortgage Calculator you are referring to is http://www.drcalculator.com/mortgage/ and this is a Java issue, not JavaScript. On my install of 17, it (correctly) says I do not have Java installed, because plugins are disabled and Java therefore will not run.

    You're welcome. I'm sorry I couldn't be more helpful, but this at least gives you an idea where to look.

    Thanks for your help today.  I am now writing on a Win7 laptop which BrowserHawk reports ver. 1.7.0_25 on both Java and Java script versions.  As TenFourFox doesn't support plugins you might consider finding a way to report that you have a java script engine and its version.
