Java & firefox 64 bit

Hello,
I`m using ArchLinux 64 bit and I want to use java. In detail I want to use www.topcoder.com(Competitions -> Algorithm) properly, but I can`t find how. I`ve already tried installing jre or openjdk6, but it didn`t work. How to do it?

How to set Java 64-bit as the default?

Hey everyone, I need to use Java 64-bit in Mac OS X Lion and I thought it defaulted to using the 64-bit JDK until I ran Minecraft which stated I was running the 32-bit JDK and if I deselect the 32-bit entry in Java Preferences it deselects the 64-bit entry as well. Does anyone know of a way to make OS X default to the 64-bit version, I also make use of the 64-bit JDK on Windows to ensure my Java applications in NetBeans run correctly on either flavour.
I did try using the OpenJDK 7 and downloaded the 64-bit runtime and installed it correctly and confirmed it was running but when running the Minecraft.app I was greeted with a message saying no compatible JDK 1.5+ was installed and when using the Terminal, it was failing to logon correctly, but was working fine in the standard JDK but like I said, I'm stuck with 32-bit in that case.
Regards, Wobby.

Does minecraft support 64-bit Java?
There isn't really a default java, but you can set the order for your preferred java. Go to the Java Preferences (/Applications/Utilities/Java Preferences) and on the General tab just make sure the 64-bit java is first (you can click and drag them to change the order).
You might also try disabling the 32-bit java by unchecking the "ON" check box next to it and see if Minecraft will run and with which Java (if shouldn't be able to launch the 32-bit one if it is off).
Good luck!

Sorry but Firefox is not available for your phone. Firefox mobile requires a phone that runs the Android operating system and a ARM CPU that supports the ARMv7 instruction set.

IE 10 on Windows 7 - 64bit: Pointing to Java 32-bit or 64-bit

Hello,
I have a Windows 7 64-bit machine with IE10 currently installed. I also have Java 32-bit and Java 64-bit installed on the machine, as both are necessary for an array of applications.
I have an application that must be invoked with Java 32-bit. When trying to open the application I am receiving a "cannot load 32bit dll on..."
I realize this exception is because the application is trying to be opened using the Java 64-bit version and this will not work.
Is there a way to set IE10 so it uses the 32-bit version of Java when trying to open this specific application, other than editing the registry settings on the machine?

Hi,
File>Properties
what IE security zone does your page map to?
Tools>Internet Options>Security tab, security zone... by default Enhanced Protected mode is turned off for the Trusted and Intranet zones...
If your java rt app requires the 32bit environment... (viz will not run within a x64 browser process)..
then you need to add a feature test to your page.
If(navigator.platform.indexOf('32')>-1){// show message that browser is using an incompatible platform)
Usually IE will show a warning asking to remove a site from EPM (64bit mode), if it detects that no x64 bit version of the Java RT is available (installed/enabled).
Post questions about html, css and scripting for website development to the IE Web Development forum... include with your questions a link to your website or a mashup.

Java 32 bit runtime under 64 bit firefox ?

I want to use 32 bit java runtime on my 64 bit Ubuntu 12.04 system. jre installation includes configuration of the java plugin for the firefox. is there any compatibility issues I should know about?

Firefox doesn't see the java plugin! This is what I did:
0. //ubuntu amd64: install g++-multilib
1. # cp jdk-6u35-linux-i586.bin /opt/java/
2. # cd /opt/java/
3. # ./jdk-6u35-linux-i586.bin
4. # update-alternatives --install /usr/bin/java java /opt/java/jdk1.6.0_35/bin/java 100
5. # update-alternatives --install /usr/bin/javaws javaws /opt/java/jdk1.6.0_35/bin/javaws 100
6. # update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so libjavaplugin.so /opt/java/jdk1.6.0_35/jre/lib/i386/libnpjp2.so 100
7. # update-alternatives --config java
8. # java -version
9. $ JAVA_HOME=/opt/java/jdk1.6.0_35/
10. $ export JAVA_HOME
11. $ PATH=$PATH:/opt/java/jdk1.6.0_35/bin
12. $ export PATH
13. $ javac
In addition to the fact, that Firefox actually doesn't see the java, there's also a problem with JAVA_HOME and PATH variables - they only save their values for the current session.

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?

Java 64-bit Windows 7 - Error with Tomcat Install

Downloaded and ran jre-6u20-windows-i586-s.exe on a Win host (Dell PowerEdge R610 with 16 Core 2.27 GHz Intel Xeon) running Windows 7 64-bit. The website said if you're running a 64-bit Windows OS then download that file.
When I run the command "java -version" it says,
"C:\Users\plozanci>java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)"
I'm trying to install Apache Tomcat 6.0.26. Getting the error: "[206 javajni.c] [error] %1 is not a valid Win32 application."
After searching the web, it looks like the Tomcat is looking for a 64-bit JRE but encountering a 32-bit version. I thought that the jre-6u20-windows-i586-s.exe file had the 32-bit & 64-bit versions. If this is true, how do I get Tomcat to use the right version?
If its false, where is the 64-bit version for Windows 7?

No. They are separate installers. The 32bit will run on a 64bit OS, but it is not 64bit. If you need the 64bit, you will need to download the 64bit installer.
You will need: jre-6u20-windows-x64.exe
Go: http://java.sun.com/javase/downloads/index.jsp
select: Download JRE
select: Windows x64
Happy downloading!

JAVA + 32 bit Borland DLL + gpib-32.dll

Hello,
I develop a Java application, which - thanks to the Java Native
Interface - communicates with a 32 bit DLL (I called gpib-jni.dll)
I wrote this DLL with Borland C++ under Windows 98.
This DLL contains .cpp and .h files that make a link between Java
classes and another library for GPIB use: borland_gpib-32.obj
Actually, National Instruments (manufacturer of GPIB products) delivers
a gpib-32.dll file to control GPIB boards.
I installed my GPIB board and the gpib-32.dll file has been installed in
C:\WINDOWS\SYSTEM directory.
When I run my program, the Send() and Get() commands of the GPIB driver
don't work.
Perhaps there is something to do, in order gpib-32.dll understand
borland_gpib-32.obj content ?
I trie
d to include gpib-32.dll directly in my 32 bit DLL (gpib-jni.dll)
, but gpib-jni failed when linking operation.
Thanks for help.

After updating Firefox and Java, Firefox gets stuck loading,will not work, and I have to use End Now to exit it.

I started to have problems after I updated Firefox and then I did a Java update, hoping this would help. Firefox will not finish loading, it gets stuck, I cannot go to websites with it, it is stuck. Then when I try to close it down, I get the message that it is not responding and I have to use" End Now". I am having to use Internet Explorer as my browser, which works fine. My computer is a six year old quite feeble PC with a 37GB hard drive with only about 5GB of available space left.

Yes, you will lose all your data stored on the sync server if you reset the sync (recovery) key.
If you do not keep changes after a restart then see:
*http://kb.mozillazine.org/Preferences_not_saved
*https://support.mozilla.org/kb/Preferences+are+not+saved
Is the password manager working properly?
You can find the sync password and the sync key in the password manager on the computer where you originally created that sync account (email).
*Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"
Look for:
* chrome://weave (Mozilla Services Password)

I have a Mac os x 10.7.4 which has Java 32 and 64 bit installed. Am unable to deposit to bank online getting a message stating I need Java 32 bit for Mac, confused???

I just got a MAC OS X 10.7.4 which has Java 32 and 64 bit installed. Am unable to make deposits on line. I get a msg stating it appears I am using 64 bit java and I need 32 bit java for MAC. I have changed order of java in preferences but it does not make a difference. Suggestions?

WHEN I OPEN ANYTHNG THAT USES JAVA FIREFOX CRASHES

I use Firefox mainly for Tazareo.com. I have 2 screens so I have Taza open for information and adding data into that system. My problem is that I cannot download anything to taza and when I try it crashes and takes firefox with it. I have contacted Taza and they said it was not on their end. My IT guy has no clue and I really need to download and upload from my computer. My work load is increasing and I need to get this problem corrected. I know nothing about computers ( I was born about the time they were being invented) So if you could give me a step by step instructions on what might be the problem, I could hopefully fix this problem. I even went into a site that was suggested on Firefox to see if Java could troubleshoot and it crashed on that site.

I play zynga games and flash with Firefox has slowed pc way down

Jave 32 Bit or 64 bit version

Please be patient with my posting as I am going to ask questions that may sound stupid but since I don't know much about Java technology, it would help me understand some things.
1) Does Java has a 32 bit and 64 bit versions or Java can be installed on 32 or 64 bit server platforms?
2) Trying to figure out what version I have installed. If I go to command prompt and type "java -version", i get the following:
java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)
If I go to Control panel, and click on Java and "About", i see the following:
Version 1.5.0 (build 1.5.0_04-b05)
If i go to System properties, and go to "Environment Variables" and look under system variables, i see that Java is installed in the following directory:
Java Name: JAVA_HOME
Variable Value: D:\j2sdk1.4.2_07
So as you can see that I am looking at different versions (builds) and not really sure which one is actually installed on the server. Any help in regard would be greatly appreciated.
Thanks,
Feddie

1) Does Java has a 32 bit and 64 bit versions or Java can be installed on 32 or 64 bit server platforms?This is not an "or" issue. Java does have both a 32 and 64 bit version. If you OS is 64 bit, you can use the 64 bit version. If your OS supports 32 bit emulation, you can also use 32 bit.
The 64 bit version currently does not have a plugin or hotspot compiler.
I don't know what a "server platform" is, but I have both on my computer.
2) Trying to figure out what version I have installed. If I go to command prompt and type "java -version", i get the following:You definately have 1.3.1_01 because it runs and tells you its version.
You definately have 1.5.0_04-b05 because it runs and tells you its version.
You may have j2sdk1.4.2_07 - why not look in the location to make sure?
So as you can see that I am looking at different versions (builds) and not really sure which one is actually installed on the serverSure, I currently have about 10 different VMs installed. The key is understanding how to use them - i.e. understanding your OS.

Forcing java 32 bit execution

Is there a definitive way to determine all the JVMs (both 64 bit and 32 bit) installed on a system (windows) programatically? I know i can do it from java control panel but I am more looking how to find it from a script.
I have a 32 bit application for which I am trying to write an installer for. I want to install 32 bit java if it's not already installed and also force 32 bit java to launch my application if both 64 bit and 32 bit are installed. On Macs I know that there is a -d32 options, is there something similar on windows.
Somehow the whole 64 bit and 32 bit java execution is very confusing :(

I apologize if I hurt anyone's feelings. I didnt mean to get into an argument at all. I take back my statements and I am still looking for an answer to my question.
I made some progress though, to detect 64-bit and 32-bit versions of java on a windows box -
64-Bit JVMs: List reg keys HKLM/Software/JavaSoft/Java Runtime Environment
32-Bit JVMs: List reg keys HKLM/Software/Wow6432node/JavaSoft/Java Runtime Environment
Now, coming to why is it important: Without getting into the real importance of JNI for a process intensive application, let's just say I am bound to use some third-party API which have 32 bit native libraries (I can't compile them now into 64 bit and neither do I want to maintain two sets of dlls). Now, this application can't be run on a 64 bit java VM. This is where it gets into a confusing design, I don't have to run a special version of windows / linux to run a 32 bit application - 64 bit versions can handle the 32 bit applications in their own "compatibility mode". So I don't understand why can't a 64 bit java have a compatibility mode to load up 32 bit native libraries. Again, I dont want to start a debate here -- I am looking for answers.

Java 32 bit 1.6

Hi,
I must have on my Air under Mavericks, java 1.6_0.35 32 bits (application support only this version), is-it possible ?

terry,
I've been trying to fix the same "internet check deposit" problem since getting my iMac last month.
I verified all my MAc and Scanner software is up to date.
I changed to 32 bit Java. Tried running US Bank app with the Chrome browser.
I contacted Apple, HP (envy100), and US Bank tech support.
HP doesn't want to talk to me because my scanner is over a year old.
Apple says since my iMac works with the scanner (true I can scan docs) the problem is not Apples.
US Bank tech support eventually said something to the effect that internet check deposits don't work with iMac at this time. It's not clear what they are doing about it, if anything.
Which bank are you using?
