I am facing issue to install 32 JVM on mac osx 10.10.5. When i run the command java -version -d32. It shows me this error.
Error: This Java instance does not support a 32-bit JVM.
Please install the desired version.
How can i resolve this error and install 32 JVM on my machine.
I have checked the Java official websites but i have not found the jdk version 32 bit version. Can anybody point me to the documentation. Also, i have searched the net but have not found any direct answer.
So, you have HUGE problem here. Oracle provides JDK in 64bit flavor only. You can always try to install JVM from Apple (1.6). As far as I recall, it was supporting 32/64 bit (to be checked):
https://download.developer.apple.com/Java/java_for_mac_os_x_10.6_update_3_developer_package/javadeveloper_10.6_10m3326.dmg
Another thing you can do is to look for OpenJDK binary with 32bit support:

i was trying to install openfire in my windows 64 bit OS, but server was not starting , and giving below error message.
which says JAVA_HOME doesn't point to 32 bit JRE,
where as in openfire site, nothing was said about 32 or 64 bit jdk version.
upon clicking ok i am getting serious of error messages,
do i need to point openfire to 32 bit jdk and jre to make it workable?
It is possible to start openfire from command line:
java -jar startup.jar
Assuming it is executed from ./lib of openfire installation dir, and you have binaries of your preferred java in system path.
The error means exactly what it said. You have either installed the wrong architecture flavor of Java / the JDK or haven't installed Java at all. If you haven't installed the 32-bit JDK yet, grab it at http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and install it. If you already have the 32 Bit JDK, change the environment variables of your system to let JAVA_HOME point to the correct installation. Refer to https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/ for further instructions. If that doesn't help, deinstall every JDK inst install the 32-bit JDK from scratch.
i have downloaded zip version of openfire , which is having this issue, i have downloaded .exe version with jre bundled, which is working fine.
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 keep getting the following message when I try to open Eclipse Juno on my Macbook Pro:
Incompatible JVM Version 1.6.0_65 of the JVM is not suitable for this product. Version:
1.7 or greater is required.
Every answer to this question suggests to download and install a 64-bit version of Eclipse. But I already have the 64 bit version and so that's not the solution I'm expecting.
This is the name of the file that I downloaded from eclipse site:
eclipse-standard-luna-R-macosx-cocoa-x86_64.tar.gz
You can see that it is the 64 bit version only. Correct me if I'm wrong.
java -version command returns this:
java version "1.6.0_65"
javac -version command returns this:
javac 1.6.0_65
But the Java control panel shows the following message:
Your system has the recommended version of Java.
Java 7 Update 67
So I have both version 6 and 7 on my machine. How do I force eclipse to use that version 7?
Make sure you set Java 7 in path and since you have both Java 6 & 7 installed, in order to avoid conflict, set it first thing in the Path variable before everything else.
Something like:
PATH=Path_to_java_7;everything else here
The most probable problem is the version of your eclipse. If you install the 32-bit version, that should work. Java Runtime is 32-bit, so 64-bit eclipse doesn't work with it!
The java library I need (jpcap) only works on Java 6, it won't work with Java 7. Is it still possible to install Java 6 on Ubuntu? According to the Ubuntu Help:
Oracle (Sun) Java 6 is no longer available to be distributed by Ubuntu, because of license issues
I've tried to use the instructions on the same site but they don't seem to work...
./jre-6u34-linux-i586.bin doesn't seem to do anything!
Check out these instructions on how to install Sun JDK 6. In older versions of the repositories the desired package is included.
If you're not obliged to, try using jNetPcap instead. It's another wrapper around pcap, it just works on more recent JVMs and is not restricted to 32 bit architecture.
I would try the OpenJDK 6 which AFAIK is fine on Ubuntu and check you have the right version 32-bit vs 64-bit for your machine. i586 is 32-bit and won't work with a 64-bit build of jpcap.
We've been using the 32bit linux version of the JavaServiceWrapper for quite a while now and it's working perfectly. We are now considering also using it on 64bit linux systems. There are downloads for 64bit binaries on the website, but looking into Makefile for the 64bit version I found the following comment, though:
# This makefile is in progess. It builds, but the resulting libwrapper.so does not yet work.
# If you know how to fix it then please help out.
Can anyone confirm, that this comment is just outdated and the resulting wrapper will work without flaws?
I've had it running in production on 64-bit red hat without any trouble for the last year or so.
From http://wrapper.tanukisoftware.org/doc/english/introduction.html :
Binary distributions are provided for
the following list of platforms and
are available on the download page.
Only OS versions which are known to
work have been listed.
(snip...)
linux - Linux kernels; 2.2.x 2.4.x, 2.6.x. Known to work with Debian and Red Hat, but should work with any
distribution. Currently supported on
both 32 and 64-bit x86, and 64-bit ppc
systems.
Take a look at http://yajsw.sourceforge.net/.
It's free and rather compatible reimplementation of TanukiSoftware Java Service Wrapper featuring free 64-bit support.
