Using a 32-bit JRE on a 64-bit platform

What is the Sun stance on the use of one of their 32-bit JREs on a 64-bit chipsets. For instance, I know that the 32-bit JVM for Solaris will work with 64-bit Solaris, but does Sun SUPPORT it.
Thanks,
T. Harris

The Installation Notes and Supported Configurations documentation spell all of this out. In, fact, 64-bit installs first require a 32-bit install.

  • How to find out if I am using a 32 bits or 64 bits version of JRE?

    How to find out if I am using a 32 bits or 64 bits version of JRE?
    If I have 2 instances of Java installed in 2 seperate directories, one 32 bits and other 64 bits on Linux. How do I identify which directory holds which version?
    Is there any command that can output this info?
    Regards,
    Billamama

    With a Sun JDK or JRE, you can use java -version:
    $ java -version
    java version "1.6.0"
    Java(TM) SE Runtime Environment (build 1.6.0-b105)
    Java HotSpot(TM) Server VM (build 1.6.0-b105, mixed mode)
    ... switch to the 64-bit JDK ...
    $ java -version
    java version "1.6.0"
    Java(TM) SE Runtime Environment (build 1.6.0-b105)
    Java HotSpot(TM) 64-Bit Server VM (build 1.6.0-b105, mixed mode)
    The last line says "64-Bit."

  • Can't use Java 64-bit install for mozilla?

    Firefox is disabling the Java installation Java 7 u4, so I uninstalled it and I am trying to either get Firefox to recognize the 64-bit Java 7 u17 already installed or install 32-bit Java 7 u17. But when I try to install jre-7u17-windows-i586.exe it fails. Can either of these problems be solved so I can use Java in-browser?
    I just uninstalled then immediately reinstalled the latest Mozilla Firefox and went into the appdata\Mozilla and install directory to clear everything in-between installs.

    Firefox is a 32-bit application, so it can't use the 64-bit plugin.
    Are you getting the download through the automatic detection here?

  • Just got a new IPOD Touch and it wont connect to our Wifi home network with a Belken N Router. Our router uses WEP 64 bit security, but had a "blank" password field, which the IPOD did not like. Changing to a 6 char numeric PW didnt help either.

    OS is whatever OS ships with current IPOD Touch
    I cannot understand why the APPLE engineers have designed this product so that it has SO MANY WIFI problems.  This is supposed to be an easy-to-use product.  We've had no problems connecting our new laptop, our ROKU box, etc, but it seems impossible to get the IPOD touch to work.  NOTHING LIKE SPENDING XMAS MORNING DOING APPLE TECH SUPPORT TROUBLESHOOTING TO LEAVE YOU IN THE CHRISTMAS SPIRIT!!!  Argh!
    In fact, the only way we have been able to get this expensive brand new IPOD to work on our home network is to DISABLE SECURITY in the router settings.  THIS IS ANYTHING BUT A GOOD IDEA.
    DON"T KNOW WHY BUT MANY OTHER USERS ARE REPORTING THE SAME KIND OF PROBLEM SO APPLE ENGINEERING NEEDS TO GET BUSY AND FIX THIS PROBLEM SO THAT NEW USERS CAN CONNECT TO THE INTERNET WITHOUT HAVING TO BE TRAINED ROUTER ENGINEERS TO DO IT!!!!
    Ok, sorry for the rant, but surely those of you who are experiencing this share my frustration.  This is not why I bought an APPLE product.
    IS THERE ANY POSSIBILITY THAT APPLE WILL NOT ALLOW A WIFI PASSWORD with more than one identical alphanumeric character?  Any ideas?  We also tried eliminating the 40 MHZ setting under Bandwidth settings in the router settings for our router, but it made no difference.  The router has the latest firmware, too.  Running out of ideas, and am ready to box this unit up and send it back!

    Thanks, Bob!  You are correct.  And, we learned this as we spoke with APPLE TECH SUPPORT by phone on Christmas day (800-APL-CARE).  One of their reps spent the time to help us troubleshoot this, but the boiled down conclusion is your answer, and to repeat for the benefit of others, here is what worked:
    1. With our Belkin router set to "out-of-the-box" WEP 64 bit security, we could not get wireless access of any kind.  Only with the Security Mode set to DISABLED, could we gain access.
    2. Changing the router's security mode setting to "WPA/WPA-2...." and entering a new min. 8 char passphrase, and then entering that same passphrase into the IPOD Touch, and restarting the router, did the trick!
    Based on this, and some info found in another posting, I can only conclude that the IPODs and IPHONES do not support WEP security mode in many generic routers used by thousands of consumers.  Hopefully, those same consumers can figure out how to change their wireless router setttings to WPA/WPA-2 security mode and ALSO get all their other wireless devices (PCs, laptops, WII boxes, ROKU boxes) all reconfigured to WPA mode, too.
    I THINK THE BOTTOM LINE HERE IS THAT THERE IS AN ISSUE THAT APPLE NEEDS TO ADDRESS WITH WEP COMPATIBILITY and it may also be the case that MOST CONSUMERS ARE USING WEP 64 BIT security on their home wireless routers?
    In any case, it's working now, so anyone who is having problems should try changing to WPA mode and post back here if it worked for them!

  • Using two or more JRE's at the same time?

    Our company uses 1.4.2-b08 as default JRE, but some departments still have 1.3.1 as standard since business applications must use this version. We've tried migrating to 1.4.2 and 1.5.0 but they were not backwards compatible (or simply not JRE compliant programmed).
    What I'd like to do is deploy 1.5.0 as 'default JRE' so that every website or intranetsite through IE6/Firefox is secure, and leave old JRE's on every workstation so that non-browser applications can still run.
    Questions:
    -if some applications run through a browser, is there a possibility through commandlines or startup options in a link or batchfile to use the non-default JRE?
    -using a link that refers to the 1.4.2 or 1.3.1 java.exe (plus the other variables for the application to run of course, instead of simply java.exe without path/directory names), seems to work fine - but does it?
    -with starting an old JRE through this commandline, do the libraries of the same the new/default JRE version get called on? I'm not sure whether Windows or the JRE first look in the environment settings of Windows XP, in the current path of java.exe and higher subdirectories or in the registry?

  • Not able to connect to wireless network using WEP 128 bit hex password

    I'm using a 128 bit hex WEP password on a Belkin wireless router.
    My ascii passphrase is 13 characters.
    I tried using the hex password generated by the Belkin router, as well as the hex equivalent of my ascii passphrase. Every time, I am told that either "there was an error connecting to the network" or the "password is incorrect" message.
    I'm using channel 7, but have also tried with channel 11.
    I tried using a $ sign in front of the WEP hex password. The $ does not work with Open Internet Connect or the Airport menubar.
    I can connect if I don't use any encryption on the wireless network, and also through the Ethernet cable.
    I have an iBook which connects fine to the wireless network.
    So why doesn't the iMac work the same way ?

    The security difference between NO encryption and any form of WEP is about 2 minutes or less for somebody looking to get in... besides having WEP enabled makes you look like an easy target since you think it'll stop anything!
    Either leave it off, making Hackers think at least 3 minutes about WHY, or use/setup WPA of one form or another!

  • Have ipod touch vers 4.2.1...using itunes 64-bit vers....error when connecting...Required software not installed...asks me to install 64-bit vers.  Done everything possible

    I am using an older ipod touch with version 4.2.1 software (newest available).  I am using itunes 64-bit version 10.7 (newest).  when trying to connect i get this error message...."This ipod cannot be used because the proper software is not installed.  Install 64-bit itunes software."  As mentioned 64 bit IS installed.  Everything was working just fine a couple weeks ago.....no idea what happened!  I have run all the troubleshooting guides mentioned by apple....uninstall, reinstall, reset ipod, etc.
    No clue what is going on.....any possibility there is a "hidden" file within itunes that is causing this problem?
    Thanks in advance to all who help!!
    Kevin

    Yes...have done this numerous times.....even found some files that normal uninstall does not delete (.itl type).
    This really weird because I have several other computers in the house that all work just fine.  ALL run Windows 7, ALL have iTunes vers 10.7, ALL sync just fine.

  • New iPad asks for WiFi password. There is none. My WiFi uses WEP 128 bit encryption, but there is no "password" to enter.

    Brand new to the iPad. It's asking for a password to the WiFi network in my home. There is no "password" as such associated with this WiFi network. It uses WEP 128 bit encryption where each byte is a hexadecimal number and is called a "key" Typing this lengthy thing in gives me no results. The iPad keeps on asking for a password. I have three computers and a DVD hooked to the network which has been working for a decade, so that's not the issue.
    Basically I'm stuck not being able to get onto the WiFi system.

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • I have a MacBook Pro Late 2011 and I'm wondering if I install Windows 7 Ultimate to this MacBook Pro with this Full Retail Version. And if so, which bit to use either 32-bit or 64-bit since I have both disks.

    I have a MacBook Pro Late 2011 and I'm wondering if I install Windows 7 Ultimate to this MacBook Pro with this Full Retail Version. And if so, which bit to use either 32-bit or 64-bit since I have both disks.

    64 bit.
    32 bit won't use all your computer's ram.
    64 bit allows you to run 32 bit programs
    Your computer is 64 bit
    New programs use 64 bit.
    There is no reason to use the 32 bit version of Windows.

  • Should I use the 64 bit or 32 bit Linux distro for Oracle Service Bus

    I'm going to install OSB for the first time on Oracle Linux 5.3 for development use. Does it matter whether I install OSB on the 32 bit or 64 bit version of Oracle Linux?
    I've had better luck with 32 bit Linux distros in the past, but if there's a benefit to using the 64 bit distro I'll use it. My hardware has 4 GB of RAM, which I hope is enough for development use.
    Thanks.

  • Error: This dialog requires using the 32-bit version of Internet Explorer 7.0 or newer

    Since upgrading Internet Explorer to version 11 this error occurs when attempting to navigate a business related website: "This dialog requires using the 32-bit version of Internet Explorer 7.0 or newer".  Using an
    XP machine, there is no issue.  Using any Windows 7 machine and Internet Explorer 11 the error consistently occurs.
    Most solutions reference this: .NET Framework problems with Internet Explorer 11 http://msdn.microsoft.com/en-us/library/dn338133.aspx.  The solution is to create the registry key
    EnableIEHosting, and references an issue with .NET 4
    The problem description and solution fit my current issue, but when I create the new registry key (in both locations), the same issue is happening.  Does anyone have any suggestions?

    Most solutions
    suggest you try Compatibility view (for IE7 Quirks mode emulation) or the Developer Tools, Emulation tab for something else.  (F12, Ctrl-8).  
    The problem is that the site is not designed to handle a modern browser and then its default is, when it can't recognize a User-Agent string, to assume the worst:  No capabilities.

    I am writting this to ask Why there is not been a release of a 64 bit version of flash for those of us that prefer to use the 64 bit browsers. I run Windows 7 Ultimate 64 bit and like using the 64 bit browsers as they run a lot smoother on my system. I am very disappointed that I am unable to get a flash player is 64 bit compatable. I know I am but one person, but I hope that others that also prefer to use the 64bit browsers would also post here voicing their desire to se a 64 bit version of Flash released

  • I am trying to reinstall iTunes 11.1.5 after the update hung. I noticed that the 64 bit installer uses the 32-bit "Programs" folder as the default. Is this correct?

    The update from v11.1.3 to 11.1.5 using the iTunes internal updater hung about 80% through the install. I had to kill it and reboot before I could uninstall the existing version since I did not know what state the program was in. When I started the reinstall using the 64 bit version, it showed a default installation directory of "Program Files (x86)". Is this correct? I know iTunes had something installed in the 64 bit "Program Files" directory.. Before I procede, I want to be sure that it is not going in the wrong place. I have a Win 8 PC.
    Thanks,
       JohnD

    Yes... that is correct.
    On 64-bit machines iTunes installs various components into the following folders (or localized equivalents):
    C:\Program Files\Bonjour
    C:\Program Files\Common Files\Apple
    C:\Program Files\iPod
    C:\Program Files\iTunes
    C:\Program Files (x86)\Apple Software Update

  • My iPad getting very warm when i use it for bit in longer time

    Why my ipad is getting very warm when i use it for bit in longer time, any body has same experience?, Why my ipad is getting very warm when i use it for bit in longer time, any body has same experience?

    The Temperature warning usually appears when the iPad has been set in a place where it gets so hot to the touch that you'd almost burn your hands if you picked it up. The temperature caused by the processor or charging the battery should never reach that level. If you feel your pad is too warm when you are using it Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

  • Use of 64-bit

    Hi,
    I am about to install PS CS5 upgrade on a Quad-Core MacPro with 8 GB. Currently, I am running OS 10.5.8 but am thinking about the upgrade to 10.6.x. I am hoping that using 64-bit will give me a much more efficient PS experience. I am a heavy PS user creating files that usually are in excess of 3.5 GB in size. I rely on filters quite heavily and usually stack 80 plus layers. I would appreciate information about using 64-bit.
    Thank you,  Gabriel

    Biggest advantage is RAM allocation (32-bit is limited to 3GB or so, 64-bit can far exceed that):
    The biggest disadvantage is 32-bit plugins don't work in 64-bit mode (I don't use any 32-bit plugins, tho)...
    +++++
    Best advice is add a lot more ram.
    Also, I recently added a 120gb OWC SSD (solid state drive) in one of my internal bays (using Icy Dock enclosure) and don't have any problems using it as a dedicated scratch disk...
