Java dosnt work on my mac ?

please can someone help me, i've downloaded java on my macbook, and everytime im trying to visit a site i cant !!! ehats seems the problem here ??

It's not a quick solution, but you could reinstall Lion to get the Java Preferences back on your Mac. Or, if you have the Lion installer set aside on an external drive, you can do it this way.
1) Right click on the Lion installer and choose "Show Package Contents"
2) Open Contents > SharedSupport and double click the disk image file InstallESD.dmg
3) Open the folder Packages. Double click the installer package JavaEssentials.pkg
4) Follow the usual steps to install an application.

  • I can't get java to work on my Mac. It is installed and enabled. I can't activate java per site because I don't get "click here to activate" box.

    I can't get java to work with Firefox on my mac with OS 10.6.8. I did everything suggested and still no luck. Java is installed, enabled, and updated. I can't even activate java per site because I don't get the "click here to activate" box for some reason. Apple support said it's a firefox problem and they can't help me. I need to be able to use java!

    hello, please update firefox to the latest version & your OS to 10.6.8.

  • How do I get Java Applets working on FF4 Mac?

    My website's photo upload applet uses Java to upload, and ever since FF4 beta releases, all the way up to the final, I get a missing plugin error. This error is ONLY on FF, it works on chrome and safari.
    Screenshot:
    http://img23.imageshack.us/i/javad.png/
    Clicking manual install goes to:
    http://www.oracle.com/technetwork/java/javase/download-138376.html
    So in other words, the manual install is pointless.
    How can I get these applets working?

    PS. I'm downgrading till this is fixed. FF4 is useless to me without this ability. I always liked FF for the better upload ability over Safari and Chrome, so I'd love to be able to use it. :-)

  • 10.6.8 Java not working. "No compatible version of Java 1.5  is available"

    Hey Guys
    Firstly I would like to thank you for clicking this question and would ask you please if you have a solution to my problem answer whatever you can.  Anyway lets get on with it.
    Recently I have been having a problem on my macbook.  I am running 10.6.8 as said in title.  Previously i was having an inactive plugin error going on and the software update said there were no newer versions available.  However when looking for a solution for this by clearing my java cache ect. i somehow ended up with this problem.  Whenever I try to run a java based application such as minecraft it says "Cannot launch "Minecraft" No compatible version of Java 1.5+ is avaiable." Also when from this menu i try to open Java Preferences it says "You can't use this version of the application Java Preferences with this version of Mac Os X.  You have Mac OS X 10.6.8. The application requires Mac OS X 10.7 or later." I did not download java 1.7 or a different version of Java Preferences outside of the software update.  If you have any idea of what's going on please help me out.  I am struggling to get on with work and games without java even working. 
    Thanks for your help

    Are you up to date with the updates?
    Update for Snow Leopard users:
    Apple issued update 12 for Java for OS 10.6:
    http://support.apple.com/kb/DL1573
    Note:  On systems that have not already installed Java for Mac OS X 10.6 update 9 or later, this update will configure web browsers to not automatically run Java applets. Java applets may be re-enabled by clicking the region labeled "Inactive plug-in" on a web page. If no applets have been run for an extended period of time, the Java web plug-in will deactivate.
    If, after installing Java for OS X 2013-002 and the latest version of Java 7 from Oracle, you want to disable Java 7 and re-enable the Apple-provided Java SE 6 web plug-in and Web Start functionality, follow these steps:
    http://support.apple.com/kb/HT5559?viewlocale=en_US
    Further update:
    Apple issued this Java related security update No. 13 on February 19:

    and Update No. 14 on March 4:  http://support.apple.com/kb/DL1573
    http://support.apple.com/kb/HT5677
    The standard recommendation is for users to turn off Java except when they have to use it on known and trusted websites (like their bank). Javascript, which is unrelated despite the name, can be left on.

  • Which CS Master Suite Products CS2,3,4,5,5.5,6 work with which Mac OSx 10.5, 10.6, 10.7, 10.8?

    You have no idea what a journey it has been to try to find the answer to all of this. Here is my stab which is open for input.
    Which CS Master Suite Products CS2,3,4,5,5.5,6 work with which Mac OSx 10.5, 10.6, 10.7, 10.8?
    - When I recently installed 10.6 on a 10.5 Macbook Pro with CS2 Master Suite, I lost all access to CS2. End of story. Unhappy ending at that.
    - I have CS4 Master Suite on a MacPro using OS 10.6.8, but my understanding is that if I go to 10.7, I lose all access to CS4. Another bad solution.
    - Apparently the same is true of CS5 and 5.5. If one goes to 10.7, you will no longer be able to use those programs.
    - The only Master Suite that is 10.8 compatible is CS6. New price $2,599, or $999 upgrade from CS5 or 5.5.
    32bit vs 64bit
    And to look at 32 bit vs 64 bit briefly. My CS4 Master Suite for Mac has two 64 bit programs, Premiere and After Effects. The Windows version of the same program also included Photoshop as 64bit.
    - I assume that as CS Suites went from CS4 to 5 to 5.5 and then to CS6, that more and more programs take advantage of the 64 bit architecture. I don't know the specifics however. Would like to know.
    - Also the MacOS has done the same. The newer the operating systems, the more the system takes advantage of mulitple processors, ram, and 64 bit architecture. Again, not sure of the sweet spot here.
    And then there was the cloud!
    Not sure what to do with that information.
    - Great, new products updates all the time
         - downside, what if the updates outgrow my computer? Size and technology?
         - What if the updates outgrow my system software?
         - What if I want to open a cs4 document 5 years from now?
              - do I have to subsribe forever?
              - if I have CS6 on my computer, do some work, and want to open it 10 years from now, I still have the software and a computer.
         - Cost of $30 a month on a special, but $50 a month normally. Sounds cheap month to month, but after two years of $50, I have spent $1,200 on a product that I don't own!
    Anyway, all of this comes up because I have multiple versions of Master Suite. I have multiple computers with various versions, and it all goes to crap if I upgrade the system software, or Adobe no longer supports the older versions. This is my contribution to the discussion. Apparently Adobe support had no archived articles to answer any of my questions, they suggested I look online. Great help. As I say, I don't much trust Adobe as my business partner anymore. I think I will work my way towards CS6 and see how long that takes me with Apple system upgrades. I'm not sure what OS 10.9, and beyond may bring as it relates to Adobe products, but I do need to get past my old 32bit applications running on an 8 core machine with 32gig of ram.
    Which brings up one final point. I have Imac with 4 gig ram, Macbook pro with 8gig of ram, and MacPro with 32 gig ram. Will 4 gig ram run Cloud CS master suite? Its a worm hole that just keeps getting deeper! I have to find a place on that slope that is cost effective and allows me to hold my position for a few years until I can see how Adobe treats its cloud cutomers, and how well Adobe and Apple play together.
    If you have any links to addtional information about various CS programs and which are ported to 64 bit, that would be helpful. I read some things about Rosetta and Java being the culprits in various upgrades to CS programs and the new Mac OS systems.
    Also, if you have any work arounds to get CS5.5 to run on OS 10.7 or 10.8, curious to hear about those as well. As I understand it, 10.8 no longer includes the previous Java or Rosetta applications, but I was under the impression that they could be installed after.

    Long story short: Simply get CC for teams. At 500 bucks a year it's a steal and those 5 licenses in the base package (or was it 10 even?) cover all your computers, at least the 3 ones you mentioned. For system requirements refer to the individual product pages.

  • Youtube, twitter, facebook doesnt work on my mac (10.4.11). It works on other networks, at the same time, these sites works on other laptops in this network

    Yutube, twitter, facebook doesnt work on my mac (10.4.11).
    I checked my mac with other networks, it worked.
    I complained to my network provider, but to my surprise, these sites
    works on other systems (HP/DEL etc) on my network but
    it doesnt open on my Mac pro.
    I wonder what the reason could be.

    I'm running v10.4.11 on an older Mac laptop with Safari 4.1.3 installed and no problems accessing those sites. Click your Apple menu / Software Update just in case there's an update available.
    Check Safari / Preferences - Security. Make sure Java is enabled.
    Cookies could also be a culprit. Back to Safari / Preferences - Security. Click: Show Cookies.
    Delete the YouTube, Twitter, and FB cookies. Quit then relaunch Safari.
    If it's not cookies, try uninstalling then reinstalling the Flash plugin which is required for all three sites.

  • Help! limewire will not work on my Mac mini 10.4.11 now that i cleaned it

    Help! LimeWire will not work on my Mac mini 10.4.11 now that i cleaned it out and had to get the new LimeWire. It keeps asking for Java 1.6 but I'm having no luck. :O( LimeWire was the reason I bought a Mac!

    Very weird day in Firefoxland
    First on a Powerbook G4 running 10.4.11 I respond to an invitation to upgrade to Firefox 4 (like a lot of others). Long story short, I wind up losing the browser altogether -- including all bookmarks. Why? Because neither the Firefox homepage (or CNET downloads) makes it clear that 4.0 is for OS 10.5 only! Amazing!
    Then I try to register to post a reply in a thread that crits Firefox for not making this System Requirements info upfront clear. But the Register page I’m taken to (https://support.mozilla.com/bs/users/register) is in SERBO-CROATIAN!!
    Then I try to log into Chat a couple of times and when it’s not CLOSED its a long line waiting and THEN it closes.
    WOW!! Are the wheels off the wagon here or what!?!

  • Java stopped working in FF 3.6.12despite having uninstalled/reinstalled latest Java

    Life was good until recently when java stopped working in FF when accessing eBay (although this continues working fine in IE).
    I have uninstalled all Java and reinstalled the latest version, made sure Java is enabled in FF, all to no avail. Clicking on Tools/Java Console does not bring up the console and most of the Java-based functions in eBay (Zoom, Enlarge, various links and buttons) are not working.
    FF version is 3.6.12 and Java is 1.6.0.22 (per javatester.org web site... which does bring up the Java console in FF, for what ever that's worth... does this indicate the problem is with eBay and not FF???).

    To avoid confusion: http://kb.mozillazine.org/JavaScript_is_not_Java
    See [[JavaScript]] and http://kb.mozillazine.org/JavaScript
    * "Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
    * "Remove the Cookies" from sites that cause problems: Tools > Options > Privacy > Cookies: "Show Cookies"
    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • Using Java SE 6 with Java FX 2.2 on Mac OS X

    Hello,
    Has anyone tried using Java SE 6 with JavaFX 2.2 on Mac OS X?
    JavaFX 2.2 System Requirements doc states that "For Mac OS X, use Java SE 7 Update 6 for Mac OS X. JavaFX 2.2 has not been formally tested with Apple's Java SE 6 implementation for Mac OS and support is offered only when used with Java SE 7 Update 6 or later.".
    So I guess that means Java SE 6 may or may not work well with JavaFX 2.2 on Mac.
    For some 'bugs' in my app, they simply don't exist if I switch from Java 7 to Java 6?
    One such bug is mentioned in this thread: Re: Unable to play mp3 files with non-English alphabets/characters in the name
    Can people with experiences in this area please share your thoughts?
    Has Oracle done additional Java SE 6 and JavaFX 2.2 compatibility testings since the JavaFX 2.2 System Requirements doc was published (http://docs.oracle.com/javafx/2/system_requirements_2-2/jfxpub-system_requirements_2-2.htm)?
    Thanks.

    Java 6 on Mac is not supported officially and not going to be supported.
    Standalone JavaFX app might work as JDK 6 on Mac was used as dev platform before JDK 7 on Mac became available.
    But this was mostly on older Mac OS X version (up to 10.6) and you may easily hit something that was fixed in Java 7 to support JavaFX better.
    Webstart/Plugin will not work. You need JRE 7 from Oracle.

  • Can't get Java to work

    Does anybody else have any issues getting Java to work in Safari 3 for Windows?
    http://www.java.com/en/download/help/testvm.xml

    Same here. I just get a window with a exclamation point infront of the Java Mug icon.
    Without Java working, I can't really use Safari under Windows (I use Java for stock market monitoring, etc).
    Hopefully I can get them working, otherwise it's back to Firefox when I'm running windows (still Safari in Mac OS X though )

  • JDK 1.4.2 java applet image printing on mac safari

    Hi there,
    I'm trying to implement printing inside java applet using javax.print package. I read an article somewhere about the package not working perfectly under mac, and a workaround is to use the old java.awt.print to get the print services, then use the DocPrintJob to print.
    The SimpleDoc I use for capturing the image that I need to print works fine, and the printServices are there. The problem I have is it's giving me an 'invalid flavor' exception when clicking 'Print' on popup PrintDialog.
    It seems that the mimetype is what's causing the problem, as the printer's supported mime type is "application/x-java-jvm-local-objectref". (note that, on PC the printing works fine, with Doc flavor mimetype as image/png and the image I need to print in png format). I tried switching the flavor to SERVICE_FORMATTED.RENDERABLE_IMAGE, printing an ImageDoc class which implements Doc and RenderableImage, but 'invalid flavor' exception still occurs.
    I don't know much about printers on Mac, so I'm not sure what I can do about it, is it something that can be controlled from the Applet or it's something that the user has to set in the system - the Applet can only warn the user and tell the user to do the configuration.
    Thanks in advance!

    SwingUtilities.updateComponentTreeUI() works by first updating the UI of the given component, and then updating the component's children (and their children). So first it will update the JToolBar's UI (which installs the appropriate borders on its buttons), and then it will update each button's UI (which subsequently installs its own default border onto the button, undoing JToolBar's border installation, thanks to the bug mentioned previously).
    Another possible work-around for this problem would be to write your own updateComponentTreeUI() method that updates the child components' UI's before updating the parent component's UI:public static void newUpdateComponentTreeUI(Component c)
         updateTreeUIs(c);
         c.invalidate();
         c.validate();
         c.repaint();
    private static void updateTreeUIs(Component c)
         Component[] children = null;
         if (c instanceof JMenu) children = ((JMenu)c).getMenuComponents();
         else if (c instanceof Container) children = ((Container)c).getComponents();
         // Children first...
         for (int i=0; children != null && i < children.length; i++)
              updateTreeUIs(children);
         // Parent last...
         if (c instanceof JComponent) ((JComponent)c).updateUI();
    }Not sure if this will present any other conflicts though.

  • Java Web Start and the Mac OS

    I am new to the Mac OS and to Java Web Start. Using Java Web Start to launch a Java application on the Mac is discussed in several of the posts here. However, in the requirement section of the Overview for Java Web Start says
    "Requirements
    Desktop/Client requirements:
    The client machine requires support for the Java Runtime Environment (JRE), version 1.3 or later. Java Web Start is available for Windows 98/NT/2000/ME/XP, the Solaris Operating Environment, and Linux."
    As you can see, Mac OS is not mentioned. Yet Java Web Start exists on my Mac. Am I looking at the wrong documentation? The document is located at
    http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/overview.html#jws
    I don't know how to use Java Web Start . I don't even know where to look for help. If anyone would care to offer some help it would be greatly appreciated.

    You are looking in the right place alright. The reason OSX is not mentioned in the document (or, by extend, any of the official sun documents) is that sun does not (may not?) provide an official java release on OSX. Java on OSX is implemented by Apple (and much to the dismay of both users and developers, they are not doing a very good job). Still, Apple's java usually fulfills the same specifications as the official sun java, so you can take any one of sun's documents on webstart or any other technology and it will usually work on the Mac. You just can't expect sun to assure that a technology will work on a platform they have no control over...

  • HT5045 Is there a way to install older versions of Java, like Java 6 Update 26 on Mac OS X 10.7 ?

    We have an application that worked fine on Java 6 Update 26. Update 29 broke the application. Even though we have fixed the problem, for people using older versions of the application, there is no recourse, if they have upgraded their OS to 10.7. So, is there a way to install Java 6 Update 26 on Mac OS X 10.7 ?

    Hello,
    I have a client that just started working remotely and needs to do payroll via her Mac OS X 10.7.5 system via a web browser. The payroll system appears to be ADP/Kronos as far as I can tell. We first tried using Safari and it said the plugin was missing so we downloaded the latest Java and installed. When we tried to run it dumped the following error. (see below)
    At this point we decided to try Firefox and rather than a dump we found the message Java 1.6.0_07 required.
    At this point we went hunting for an older version of Java and did find one only to be told if was specifically for OS X 10.5.x. My client is running OS X 10.7.5.
    I have other clients running Windows that have multiple (older) versions of Java installed including 4, 5 and 6 all on one machine so I'm not sure if this is possible on Mac OS X or not.
    Note I am not in charge of the payroll system and have no way of updating that side of things. I may recommend that my client contact her internal Help Desk or revert to using a Windows based system as I know for sure that would be capable of handling these requirements.
    Thanks, Jason
