Is jre 1.7 (32 bit) compatible with windows 7 64 bit OS ?
I am using jre 1.7 update 9. When I login into the application, it is not opening. This is a jre issue but I wanted to know if 64 bit OS supports 32 bit jre. Application works fine with a 64 bit jre. But I want to make it 32 bit compliant.
The Windows 32bit JRE can run on Windows 64bit.
You are saying that you're trying to "log into" your application. Is that an Applet?
If so, then you have to ensure that your browser runs in 32bit mode:
If you install the 32bit JRE, then the Java Plugin (allowing you to run Applets) will only work under 32bit browsers.
If you install the 64bit JRE, then the Java plugin will only work under 64bit browsers.
To support both 32bit and 64bit browsers, you have to install both JRE's.

I can't find anyone else running into this issue so I keep feeling like I must be missing something here. Our framework has been working fine on Win7 and we are now trying to test our scripts to make sure they work in Windows 10 as well.
We are using the 32bit IEDriverServer.exe, but in Windows 10, it's starting up the 64bit version of IE instead of the 32bit version. If you read the documentation on IEDriverServer.exe, it says the 32bit version will open 32bit version of IE, and vice versa for the 64bit IEDriverserver.exe.
Does anyone know why on Windows 10, we are seeing the 64bit version of IE opening? (Not edge but IE11 on Windows 10).
I have installed jre7 and jdk 7 on a windows server multiple times.
I have configured java home and jre home variables.
Java for browsers is set in the control panel.
However, java plug-in is nowhere in firefox add on's , and acts like java is not installed : you need java plug in to run this applet.
Any ideas?
Which version of Firefox are you using, 32 or 64 bits? The new version of Firefox for Windows, 64 bits, does not recognize the Java Plugin, see it in :
https://support.mozilla.org/en-US/kb/use-java-plugin-to-view-interactive-content
Firefox 32 bits recognizes the Java Plugin.
I downloaded Solaris 5.10 VM (ova) for VMWare (win7 pro) and I am trying to update the pre-installed java6 x64 to java 7_79 x64 JDK from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
It seems I have 64bit support (isainfo returns amd64) and I am trying to determine which is the correct java64 download. I am confused.
I tried Solaris x64 16.38 MB jdk-7u79-solaris-x64.tar.gz but when I run java -version I get
Error occurred during initialization of VM
A fatal exception has occurred. program will exit.
I also tried another download
Solaris x86 96.66 MB jdk-7u79-solaris-i586.tar.gz
but that as I suspected, turns out to be 32bit only.
I did not try the Sparc ones as I suspect they are for Sparc arch.
Help appreciated.
You need to install both the 32 bit and 64 bit packages. The latter is not, as its size shows, a complete JDK but only an add-on including the 64 bit binaries/libraries.
Sorry for the delay. First, uninstall all versions of java. Seconds, I noticed that the link you provided is out of date. Java 8 came out recently so you should use that unless you have compatibility issues.
Java 8
Choose: Solaris x64
Finally, if this does not work, uninstall and just try again with a different download from the page I provided.
i have downloaded and installed jdk 1.7.0_71 on my windows 7 home basic 64 bit lenovo laptop.
Now i need to download IDE.
I was recommended to install eclipse Galileo( as i will be using the same in future) IDE for Java EE Developers but i cant find 64 bit version on eclipse website.
Only 32 bit windows version is available.
Will the 32 bit version works for 64 bit and will it be compatible the jdk i have installed?
There is no 64 bit version because 64 bit Windows was not very popular at the time Galileo was released. You need 32 bit JDK to use 32 bit Eclipse. It should work on 64 bit Windows though. Are you sure you are supposed to use 6 years old Eclipse?
JDK and Eclipse are both different they are not dependent on each other, but if your system is 64bit then use JDK and eclipse 64 bit. you can download eclipse from here you can go for eclipse Luna it is latest release.
I'm looking for a 1.7 JRE which I can distribute with my Java application on OS X. Oracle only offers a 64-bit version of the JRE for OS X, which means that I cannot support older 32-bit Macs. Is there a 32-bit version somewhere?
Apparently there isn't. At least the only definitive thing I could find was this:
Mac OS X System Requirements
Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.*
Administrator privileges for installation 64-bit browser Note that
installing Java on a Mac is performed on a system wide basis, for all
users, and administrator privileges are required. You cannot install
Java on a single-user basis.
A 64-bit browser (Safari, Firefox or Chrome, for example) is required
to run Oracle Java on Mac OS X. 32-bit browsers do not support Java 7
and later versions on the Mac platform.
Users with Mac OS X versions 10.6 and below should go to Software Update under the Apple menu to look for updates.
And there isn't anything for 32-bit Mac OS X on Oracle JDK8 download page either.
It safe to assume that there is no Java 7 or newer for 32-bit Mac.
