I have a 64bit jdk 1.6 installer . Can I install java on centos 5.8 32 bit using a 64 bit installer. If so what would be the command to achieve the same.
TIA.
No you can't because a 32 bits OS doesn't provide 64 bits support. The reverse is true though, you can install a 32 bits program on a 64 bits Linux.
Specifically in the case of Java program though, except for those programs that require huge heaps you should be able to get the to run on both a 32 bits or 64 bits JDK, so it's worth a try to install the 32 bits JDK and try to execute the application.
Simply, no you can't. To run a 64-bit application, you need an OS that supports 64-bit apps, and a 32-bit OS does not do this.

If I install 32 bit Android Studio in 64 bit Windows system, will it work properly?
Yes. This is true in general for almost all programs -- the 32-bit version will work on a 64-bit system. A 64-bit system can be seen as a "more powerful" version of a 32-bit system, which has limitations (e.g., maximum amount of RAM) that a 64-bit system doesn't (at least not to the same degree).
It seems like linux ARM architecture supports only 32 bit java.
my OS architecture is [Linux 3.18.7-v7+ arm] and it is a raspberry pi.
I have tried installing both 64 bit and 32 bit java from below link.
Java 32 bit works but java 64 does not.

after installing 32 bit java if "java -version" command is executed it successfully returns version. like Java version : 1.8.0_77. But after installing 64 bit java if "java -version" command is executed it shows error : "unable to read binary file"
Is it really correct that only 32 bit java is supported for arm architecture
Till RaspberryPi-2 until OS is 32-bit, so a 32-bit OS can not install the 64-bit java.
What does the "IA64_32" option mean in the architecture plugin details. The complete list of options is here, but there is no detailed explanation.
osgi.arch processor architecture x86, x86_64, ia64, ia64_32, ppc,
PA_RISC, sparc
The problem I am facing is that I have 2 implementations of the same interface, one for 32 bit set with x86 and another for 64 bit set with x86_64,ia64, but for some reason neither start when I install the 32 bit version of the application on a windows 2012 server r2 64 bit.
Many thanks in advance.
ia64 and ia64_32 are for Intel Itanium processors (64 bit and 32 bit respectively I think). Eclipse only uses this for HP-UX support. Recent releases of Eclipse only support ia64.
Windows builds normally use x86 (32 bit) or x86_64 (64 bit).
so the questions as in the title, I need to run my server application in Tomcat on a System which is 32 bit Windows XP, I am working and compiling on my 64 bit Windows 7 in Eclipse. How do I compile it to 32 bit, what do I need to do? I assume it won't work on the 32 bit Windows when I'm compiling it on a 64 bit machine?
Java doesn't build 32-bit or 64-bit applications - bytecode is portable across different bit architectures.
The only exception is native libraries that you might be using in your code. If there are any then you will have to manually compile those for the respective platform. Otherwise the java code is totally portable across 32-bit and 64-bit platforms.
The problem is your JNI DLL, which needs to be compiled for 32-bit to match the 32-bit JRE.
Java is independent of the OS.
You can compile with your 64bit machine and run this on a 32bit computer as long as this computer has a 32bit VM.
If you're still searching for some "simple" solution, one would be to install a 32 bit os in a virtual machine and run eclipse from there.. Very ugly I know, but it works.
Another approach is mentioned here. How to launch java swing app which used precompled DLL from cmd?
You could install a 32bits jdk on a 64bits machine. point the JAVA_HOME to this jdk and use it. It
I got eclipse RCP juno 64 bit crashes on Mac OS X, and I posted this question in StackExchange Mac - https://apple.stackexchange.com/questions/67104/eclipse-rcp-juno-64-bit-crashes-on-mac-os-x. And, I guess I have no choice but to use 32 bit version now.
Is it just OK to use 32 bit eclipse on 64 bit OS (Lion), and 64 bit java (java 1.7 sdk)?
How about the code compatibility? Can I open the workspace with 64 bit eclipse created from 32 bit eclipse?
What's the difference between 32bit and 64bit eclipse? Or, what are cons and pros between them? Why do they keep 32bit eclipse in 64 bit world?
You need to 32-bit JVM to use 32-bit Eclipse, and you need 64-bit JVM to use 64-bit Eclipse.
Note that a 32-bit JVM can run on 64-bit OS. I have Windows 7 64-bit with both 32-bit and 64-bit JVMs installed. I do have to sometimes edit eclipse.ini file to make sure that the correct JVM is selected.
There are no workspace compatibility differences between 32-bit/64-bit variants of the same version. The native bits that are 32-bit/64-bit specific are for native UI and file system integration.
If you are running 64-bit OS, you should favor using 64-bit JVM/Eclipse. Doing so will avoid a lot of memory issues that plague 32-bit installs. For instance, it isn't uncommon for a 32-bit JVM/Eclipse to fail to start with -Xmx1024m due to address space fragmentation.
The 32-bit Eclipse builds are still produced because there are still quite a few 32-bit OS installs out there.
