I have Windows 7 with 64 bit environment.
Configuring gateway,
I run NSS3.12.4 32 bit on 64 bit platform and got this error.
Libnspr4.dll Can't load IA 32 bit .dll on AMD 64 bit platform
Java is 64 bit. How to get NSS 64 bit package?
Is there any way to fix this error if I will work with NSS 32 bit?
Thank you for your help!
I don't know if there is a simpler answer, but you could download the sources and build them to create a shared library for your platform:
JSS information
NSS & PSM Downloads
NSS Build instructions.
As far as I know there's no way to do that on 64bit Windows OS.
In order to use NSS on Java, you need to go through SunPKCS11 provider, which is according to Sun documentation:
The Sun PKCS#11 provider is supported on Solaris (SPARC and x86) and
Linux (x86) in both 32-bit and 64-bit Java processes. It is also
supported on 32-bit Windows (x86) but not currently on 64-bit Windows
platforms due to the lack of suitable PKCS#11 libraries.

I see this in the Java Control Panel
Platform: 1.8
Product: 1.80_131
Location: http://java.sun.com/product/autodl/j2se
path: c:\Program Files\java\jre1.8.0_131\javaw.exe
architecture: x86_64
The Architecture value, x86_64, suggest both 64 and 32 bit but the Java web app that I am trying to access, Oracle Discoverer, part of the Enterprise Business Suite, only works with the 64 bit Internet Explorer, suggesting to me that 32 bit Java is not installed. Is it? Or is there a problem with it?
x86 and x86_64 are both architectures; the first one is 32 bits and the second one is 64 bits. You can install as many java versions as you want side-by-side, you would just point to the one you want your application to use.
The x86_64 means it is a 64 bit architecture (see also x86-64 on Wikipedia), if it had been 32 bit, it would just have been x86 (see x86 on Wikipedia).
In any case, it is perfectly fine to install a 32 bit Java next to a 64 bit Java.
x86_64 means 64 bit java.And the path "c:\Program Files\java\jre1.8.0_131\javaw.exe" also proves that you installed 64 bit java, otherwise, the path should start with "C:\Program Files (x86)".
64 bit Internet Explorer can access both 32 bit and 64 bit java web servers.
Internet Explorer does not need to run on java environment(unless you are developing a Applet application.) which means you can run Internet Explorer without java.
Conclusion:
Your environment has installed 64 bit java, and there is no problem to you!
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 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 been working in Java for past 8 months. Currently I am using JNA to load a third party DLL and it works fine on 32bit WinXP and 32bit Win7 machines.
On a 64bit Win7 machine, this third party dll is present under C:\Program Files(x86), I assume this means its a 32 bit DLL. So, here is the configuration I used so far,
Win7 machine - 64 bit,
Third party dll - 32 bit (as per above mentioned assumption),
JRE - tried with both 32bit and 64bit
But I get the following - "error: java.lang.UnsatisfiedLinkError: Unable to load library 'Wrapper': The specified module could not be found."
Please let me know if JNA supports loading a 32bit DLL, using a 32 bit JRE on a 64bit machine. Also, if this 32bit DLL has dependencies on other 32 & 64 bit DLLs would JNA still support it.
I am going to use procexp to find out if I am missing any dependencies. I will update this post accordingly.
Please provide your expert advise. Thanks in advance !
JNA does support loading 32 bit DLLs on a 64bit machine. But we need a 32 bit JVM to do this.
I was using Platform.is64Bit() to determine the path of the DLL. I learnt that this method returns the configuration of the JVM and not the OS.
So, in my case when I was using 32bit VM on 64bit machine, the path to the DLL was wrong.
I am new to JOGL. I use Eclipse and I imported JOGL jar and dll (yes, Windows OS). But, when I was searching for JOGL libraries, I downloaded 32 bit version. I have 64 bit OS, but since I can run 32 bit apps I thought it will still be more suitable. But compiler is complaining: Can't load IA 32-bit .dll on a AMD 64-bit platform
Well, first, I thought Java itself is NOT separated by architecture. Yes, I know I am using native libraries to link into Windows OpenGL interface (API), but I just want to include these code snippets into java bytecode, so why compiler cant let me use 32 bit ones? Thanks.
Since you have a 64-bit OS, you installed the 64-bit JVM. The 64-bit JVM cannot use the 32-bit DLLs, so you'll need to either download the 64-bit ones, or alternatively, install the 32-bit JVM on your system and set Eclipse to use that JVM instead.
64bit JVM cannot load 32bit libraries. You need to start 32b JVM to make it work (or get 64b dlls).
