Java 8 JSE+JDK : Install 32 or 64 bit?

Hi. A "noddy" installation question...
With Java 7 it was advised to install Java 32 bit even on a Windows 7 64 bit machine to give 32 bit web browser compatibility.
Is this still the case for Java 8 JSE and JDK (and Netbeans)? Or have they fixed the browser incompatibilities so that a JSE 64 bit install works ok?
The Oracle Java 8 installation instructions are unclear on this. They talk only of installing JSE 64 bit on 64 bit Windows and the old 32 bit .v. 64 bit advisory only covers Java 6 and 7 (perhaps because its not been updated for 8) - but it does advise using JSE 32 bit for 32 bit browsers on a Windows 64 bit machine.
Many thanks.

Unfortunately my "Answer" (to use the version that suits the browser) is contradicted by a Warning when I tried to install the 32 bit JDK+Netbeans Cobundle
JDK and Netbeans are NOT your browser. Install whatever you want for Netbeans and general JDK use.
The JRE used with the browser should, as the advice told you, match the browser (32/64 bit) you are using.
Use the Java Control Panel to configure the JRE installations that you want the browser to work with.
The runtime versions you configure AND enable in that panel determine what Java versions are 'active' as far as windows is concerned.
Go to Control Panel -> Java to open the Java Control Panel.
Then select the Java tab and 'view' to see the JREs that are configured.

Java ME SDK 3.0 on Vista 64bit (JDK/JRE1.6U13 32-bit installed right before

I really would like to test the recently promoted release of Java ME SDK 3.0 on my Windows Vista Ultimate 64-bit.
First I tried to install it using my previously installed JDK 1.6 64-bit. Installer failed to properly integrate with Vista's UAC. Then equipped with proper permissions installation succeeded. So I tried to start the app. Got a splash screen telling me to start modules. Next I saw a apparently neverending list of exceptions appearing once every 10 seconds. So I told my task manager to drop that process.
I tried to uninstall the application and had to see uninstaller failing due to not support 64-bit Windows. Great. Java=Portability???? And why didn't installer tell me about it?
Lacking opportunity to uninstall the ME SDK I decided to drop every update of JRE and my existing JDK, then ask regedit to drop any registry information on any sort of Java-related stuff. Next I dropped all left-over folders related to installations of Java or Java-bundled software. Completing this I got a fresh JDK/JRE 1.6 Update 13 32-bit and installed it to my computer without any trouble.
Next I decided to have another test of installing and running Java ME SDK 3.0 ... interesting: installer detected an existing installation (where from? all folders as well as lots of registry keys had been dropped before, even Windows' application manager didn't consider to have an existing installation anymore). The installer found new JDK installed before and finally succeeded to reinstall the app.
Well, I tried to start it after that expecting something tested and thus working now. Instead of that I got the same sequence of exceptions requiring me to ask Task Manager for help after two bothering minutes of cancelling exceptions on splash screen not showing any kind of progression anymore.
Here's my question (aside from: Who on earth started to falsely proclaim Java being platform-independent?):
How can I get rid of these problems and have that super-app running on my two and a half years old operating system?
Any support is welcome!
Thomas
(PS: I admit to have very bad view on Java as a technology due to stepping from trouble to trouble for years now and so I guess no one's ever able to convince me of the contrary, so please ignore any dismissive statement on it above. And yes I'd like to see this app running so I can start developing apps for mobile phones or at least test its capabilities in comparison to the competition.)
EDIT: A few months ago I was testing some ME SDK with success. I can't remember version or included IDE. Is there any (basic) difference in using "Java ME SDK 3.0" as currently promoted on SDN from using Netbeans 6.5 supporting Java ME as well?

Hi, I also used the 64 bit sdk with Java ME SDK 3.0 and I am now unable to unistall it. I tried the suggestion of editing the 2 Java files which as suggested allowed the program to work correctly however I was unable to uninstall the program. So I tried the other suggestion of removing the files and then reinstalling linking to the 32 bit SDK which again it works OK but I am unable to uninstall.
On trying to uninstall I get the error:
Cannot load native library from path: native/jmesdk/windows/windows-x86.dll

Hello everyone,
I am a very newbie I am trying to download and install sun java jse 6 for windows xp pro. I have downloaded jdk-6u1-windows-amd 64 and jre-6u1-windows-amd 64. I am not sure what java i need i am not a developer i just need sun java jse to enable me to install certain software. first of all when i search download for sun java jse 6 i ended up with jdk-6u1-windows-amd 64 and jre-6u1-windows-amd 64.
when i try to run and install jdk-6u1-windows-amd 64 i get
This installation package is not supported by this processor type. Contact your product vendor.
I have window xp pro x64 bit
I am at a loss any help would be much appreciated.

well you probably do not have an AMD processor but an intel processor. I suggest you go to http://www.java.com and follow the installation procedure there. That will install only what you need.

The JDK installed in directory /usr/java14 does not support the 64 bit data

I'm installing the Java Add-in for the ECC 60 SR1 and suddendly during the instalation of the module for the creation od the db schema I recive the error:
"The JDK installed in directory /usr/java14 does not support the 64 bit data model"
I'm using the JSDK 1.4_2 SR3 for AIX, and till now this JSDK was the rigth JSDK for the installation.
What does it means ? DO I have to download the latest JSDK for AIX ?
The only thing changed at Os level before of that error on the JSDK is the installation of the latest perating system patch, but I should be very surprised if there is a relation with the error I'm reciving now.

Installing Java on a Windows Vista 64 bit OS - amd64 Turion X2

I do hope there is someone who has solved this issue. Spent several hours and multiple loads to no avail. Currently using a HP laptop with Windows 64 bit OS running. The processor is a AMD64 Tution X2. Java loads but no entry in Internet Options advanced settings or an icon in the Control Panel. When I execute the application which requires Java nothing happens.
I am at a loss of what to do next.
userlm

I realize this is an old post so this may no longer have any relavance.
Make sure you have downloaded and installed the 64 bit version. The 32 bit will install on the 64 bit machine and will not appear in the standard control panel. If you look at your control panel, look to the bottom of the list for the icon labeled "View 32-bit Control Panel". If you installed the 32 bit version, the java instance will be there.
You can install both the 32 and 64 bit versions on the same machine. Remember most installs to a 64 bit machine will put DLL's and the like into the system32 folder for 64 bit apps and into the syswow64 folder for 32 bit apps.

Installing Java SE JDK on top of JRE?

Hi List,
this is my first post here and I just have a somewhat general question about best
software installation practices. I want to install the Java SE JDK on my Windows
x86 system and already have the JRE 7 on it.
Now there are two choices I see myself having:
1. deinstall JRE 7 and install a freshly downloaded JDK 7, which includes the JRE.
or
2. simply install JDK 7 over JRE 7.
Are there any differences? Maybe it doesn't even matter how I do it, but this is
something I don't know?
Thanks

This is basics of the basics of windows usage you're asking about. If you want to be lazy just install, if you want to be safe uninstall and then install. Either way, it all depends on how you've treated your software installation what the end result is going to be. If you have a clean system either way will work just fine.

O/s Win XP 64 bit - Java latest version installed but Firefox Nightly 64 bit will not recognise it after re-install 3 times & re-loading FireFox, IE does see it

Although I had Java latest version installed and IE and Chrome recognise it, i can't get Firefox Nightly 64bit to see Java. Websites with Java functionality in Firefox report that i need to install Java.
I re-installed 3 times, I cleaned out older Java versions and did all other steps in Firefox help articles.
If I go to Firefox plugins page, its says the only plugin I have is Shockwave. If I select the Java option, it tells me to download and install Java - which I have done before several times.
I have shut down and re-opened Firefox many times to get it to see Java.
Java is installed to c:/Program Files(x86). Is Firefox looking for Java in c:/Program Files ??
The website in question is the nVidea driver download page at http://www.geforce.co.uk/drivers, where the auto-detect correct driver function is a Java function. In the end I had to use IE to run the Java function.

Does Java 7 run on only x64 bit MAC OS X?

I want to deliver self-contained application packages on Windows, Linux and Mac so I have build my JavaFX application on all three platforms. I will allow my users to download these native bundles from my application's download web page but I have a confusion regarding MAC users because For Linux and Windows, JDK/JRE 7 comes in two download options
1. for x86
2. for x64.
but for MAC we have only option for x64.
Java Download Page shows Java/Jre is not available for 32 bit MAC OSX to run JavaFX application. Does it mean JavaFX will run on only x64 bit MAC OSX?
If it is so, then my issue has been solved, as I have already bundled my Javafx application as a "Self-Contained Application Packages" after run custom build.xml script on x64 MAC OSX but if it is not so, the user can also run JavaFX application on x86 MAC OSX but in that case my "Self-Contained Application Packages" for mac would not run on x86 MAC OSX.
So I am planning to give an additional zip file that either contains app (without copy of jre) or a plain self executable jar. But I'm bit worried regrading - what exactly I need to bundle into that zip file with self executable JAR so requirements must be met to be able to run my JavaFX application in following conditions?
conditions are : -
1. If user has x86 MAC OSX.
2. If java is already installed on user's system. And he would not like to download the "Self-Contained Application Packages" from our download page.
3. Big download size.
So what among the following two options suits if user have x86 MAC OSX or if he has already installed java on his system or he would not like to download "Self-Contained Application Packages" from download page due to big download size?
Option are -
1. APP ( without inbuilt copy of JRE)
2. Or only a self executable jar.
I am not sure that Mac OS X 10.7.3 (Lion) or later version can run on x86 system.So in case of #1 option the user may have trouble if he is using x86 system. Then he may need to change info plist file and replace the JavaAplicationStub.
In case of #2 option I think is better as the user need to download the JRE only and the JAR should run using "java -jar" command.
Please suggest which option is better in case if JavaFX application can run on x86 bit MAC OS X?

JavaFX will run on only x64 bit MAC OSX?Yes. There is no 32 bit JavaFX 2.x+ build for OS X.

Cannot install sqldeveloper 64 bits on windows 7

I am trying to install SQL Developer on windows 7. I unzipped it under C:\program Files\sqldeveloper ok
I run it as administrator
it asks for the path to java.exe, so I provided it and I get Cannot Find J2SE SDK installed
I searched and found that there are 2 common issues:
1. the JDK is not 64 bits
2. The path is for JRE and not JDK
I installed the following 2 files:
sqldeveloper64-3.1.07.42-no-jre.zip -> 64 bits SQL Developer
jdk-6u31-windows-x64.exe -> 64 JDK
So my question is how can I verify that I have the right files? What file is the SQL Dev looking for so I can search it.
How can I re-validate that my software (both, SQL Dev and JDK ) are 64 bits besides the name of the installation files.
Thanks

Hi,
If you have searched, possibly you came across this post:
Re: Unable to start Oracle SQL Developer
Note that on Windows 7, any installer conforming to Windows rules will install 32-bit software into C:\Program Files (x86)\ and 64-bit software into C:\Program Files\. Since SQL Developer installs via a simple unzip, if you wish to install both versions on a 64-bit Windows OS, it is best to follow that rule also to prevent becoming confused about which one is which.

Gary

Which Java version to install on Windows w/AMD Athlon 4400+?

Hello all,
Until now, I've always run Windows on an Intel Pentium platform. However, I just purchased a new PC with an AMD64 Athlon 4400+ processor (one of those new "dual core" jobs). According to the PC manufacturer, this processor can run at 64-bit or 32-bit, but by default, is set to 32-bit processing.
Here's my question:
Assuming that I'll be running this machine as a 32-bit processor, which version of the JDK should I pick to run on this new system? Windows/Pentium or Windows AMD64?
Thanks for your help.

Be careful here.
I went out and bought a nice new AMD64 cpu and
installed the beta Windows XP 64 bit edition and then
tried to install that 64 bit Java for AMD and never
got past the install. Windows kept killing the
installer insisting it was either a virus or
unauthorized or some such nonsense.
After not being able to install other 32 bits apps
(and I had no problems with other 32 bis apps, mind
you) I finally removed windows 64 and installed
Windows XP Pro and Java 1.4.x without issues.
Conclusion: Install the 32 bit Java if your OS is 32
bit, install the 64 bit version of Java if your OS is
64 bit (if you can). Your hardware makes no
difference if it can operate at both 32 and 64 bits.
Then it depends on the OS that you're running
g because it will tell your CPU which mode to operate
in."Windows XP Professional x64 Edition is designed to meet the demands of customers who require large amounts of memory and floating point performance in areas such as mechanical design and analysis, 3-D animation, video editing and composition, and scientific and high-performance computing applications. "
- Microsoft
"If you use only 32-bit applications and work with data sets not larger than 2 GB, you will find that 32-bit, Windows XP Professional is the best desktop system for your applications."
- Microsoft
Are you even doing anything Windows 64 is designed for? Unless you're running in a 64-bit environment you shouldn't be downloading the 64-bit Java, whether or not your processor can support 64-bit environments is irrelevent. If you're a Windows user, then chances are you shouldn't be using Windows 64 because unless you require massive amounts of processor power and memory for things like animation or engineering it's not for you.

How can I run a application on a machine without JDK installed?

Hi all,
I'm new to java,I want to know if there's a way to run a application on a machine without JDK installed, I noticed that some server application such as Domino have CORBA applications running in background,how can I set up such environment without JDK installed?
Thanks.

I believe there are two basic ways you could go about this.
1) Install the JRE (Java Runtime Environment) on the machine in question.
2) Use JSP to make a server side app that interacts via browser on the local machine.

My Applet loads only if java sdk is installed...

I have developed an Applet which reads an image from the server (its serving host) , edits it and then writes a stream back to server, which is captured by servlet that writes the stream to a file.
I have deployed this in a web application (in Tomcat 5 .0) /webApps/Images. The jsp page accessing the applet and the jar file containing the code are placed directly under the root directory.
(I have used jdk1.4_06)
Everything is fine when i run this applet from my own system (using my system ip and port 8080 like http://...:8080/Images/Rapp.jsp ) and on other systems having jre installed (sdk 1.4 ). But when i try to invoke this applet from other machines w/o java it displays Applet not inited or Class not found exception.
This applet is a part of web site and so i can't expect all the users to have jdk installed. I don't even think i need to sign my applet as i need not access the client system.
I have been trying to find the root cause of this problem but in vein.
Please somebody help me out. Thanks in advance.

I do agree with you that the jre could be smaller but you need a jre to run applets.
With the jdk there is a msi (microsoft inistaller) of 10MB
(user.home)\Local Settings\Application Data\Sun\Java\jre1.5.0_04\jre1.5.0_04.msi
The cab file to install the jre from codebase using the object tag with clsid is located here:
http://java.sun.com/update/1.5.0/jinstall-1_5_0_04-windows-i586.cab
Note that you need mozilla to download it because IE can't do it for you.
And it's a verry small cab file executing a program that needs to fetch the rest
of the jre from SUN's website (in other words just pray it is still there when
youre clients run it)

WLS_1032 install on linux64-bit. Where is the .jar installation software

In the wls install document they reference using a .jar file to use when installing wls_1032 on a linux (RH5) 64-bit machine. In the WLS download area I only find wls1032_linux32.bin.
Any help as to where I can find the right .jar file to download would be very helpful. Or I'll have to go ahead and install the 32-bit softweare, which seems kinda' silly in this day and age.

Hi,
You can download the generic.jar from this site and there is a explanation like below.
"This table includes links to WebLogic Server installers that include 32-bit JVMs for the platform in question, and links to WebLogic Server generic installers that can be used on any supported platform. To use WebLogic Server with 64-bit JVM's on Linux and Solaris or to use WLS on other supported platforms, use the WebLogic Server generic installer listed under "Additional Platforms". The generic installers do not include a JVM/JDK. For instructions on using the generic installers, see this document."

Where is "javac" after JDK install?

I am having a problem just getting the first HelloWorldApp to compile the Java\jre1.6.0_06 JDK
I get the "'javac' is not recognized as an internal or external command, operable program or batch file" and followed SUN's troubleshooting directions so I'm sure and I am sure it is not a path issue.
Should there be a "javac" file in Java\jre1.6.0_06\bin where the JDK is installed?
I can't find one and I have reinstalled the jdk 2x and made sure I checked all options to install everything. This was from the latest Java SE JDK from SUN (jdk-6u6-windows-i586-p.exe)
Thanks

You're mistaken. It's a path issue.
Should there be a "javac" file in Java\jre1.6.0_06\bin where the JDK is installed?
No. The JRE is not the JDK. You've got the wrong path.
