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 have two versions of Java installed on my computer:
I have allowed java to run in the browser:
Java is running in command line:
This is the error I get:
I have also enabled scripting in the browser settings. I have restarted the computer and I have also tried uninstalling all Java and reinstalling it. I am not sure what else I can do?
Could you check the below settings(as shown in screenshot) is enables in your java control panel.
I have solved it. Even though I am using a 64 bit machine, if I install a 64 bit version of Java it will not work. I installed a 32 bit of Java and now it works.
I've windows 64 bit system.
In this I have installed java 64 bit version and I've downloaded the eclipse indigo of 64 bit also. I've set the JAVA_HOME path to this 64 bit java installation location. I'm using this for J2EE development. Everything is fine up to this.
Now I've downloaded the 32 bit version of java and installed in my system and also I have downloaded 32 bit version of eclipse. Now I want to use this for android development. So how could I set the class path of this 32 bit version java.
How could I use both on my machine.
I'm looking for your replies.
Thanks
What matters is not what is used for running Eclipse but what is used for compiling your code. You can set this #
windows->preferences-java-installed JREs
The build environment uses different java version based on the configuration. you can install any number of Java version (X86 or X64).
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.
after reading "Google chrome custom JRE/JDK/plugin" I decide to post because I do not get the desired behaviour.
OS : Windows 7 64 Bits.
Browser : Chrome version 20
I want Chrome to use C:\Program Files\Java\jre7\bin\plugin2\npjp2.dll (that is the 64 Bits java plugin).
I launch regedit and go to the wow6432Node/Mozilla ... and change the path attribute of the #java.com/JavaPlugin node to my npjp2.
I quit chrome and restart : Chrome tells me that Java is not installed.
If I put back the previous version C:\Program Files (x86)\Java\jdk1.6.0_10\jre\bin\new_plugin\npjp2.dll, Chrome tells me that my version is obsolete.
This proves that I Hack at the correct place but I cannot make it take the JVM 64 Bits.
After googling some more, I found this http://www.java.com/en/download/manual.jsp#win and this piece of info is interesting :
We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers.
Which means That I need to install the 32Bits version of the JRE just to make Chrome happy:)
I leave the post for future googlers :)
Any ideas ?
I think only Internet Explorer can use 64-bit Java, other browsers can only work with 32-bit Java.
The easiest way to go is to consider Chrome a 32bits app and give it a 32 bits JVM, and so even on a 64 bits Windows OS.
Interestingly, on MAC OS X Snow Leopard latest updates, no issues whatsoever : it works like a charm with the native jvms. I wonder what would happen if I played with the default jvms also...
When I install version 7 of Java on my windows 7 64 bit machine (I install this version 64 bit, windows with SDK) then Java does not launch when entering a website with applet. But when I use version 6 everything works fine.
On the other hand, while compiling (with Netbeans 7.1.1) everything works fine on both of these versions. Java programs also work fine when launched from command line with java command.
What is going on?
EDIT
Now I have tried reinstalling everything with Java 7 update 4 (64bits) but it still does not work. The problem might be somewhere in PATH variable because the java icon does not appear in the tray when I am entering a site with applet but still - I have added C:\Program Files\Java\jre7\bin to PATH and it does not work.
The Java Plugin must be in same hardware specification than the browser.
So if you install Java 64bits, it will run in IE 8 or 9 64bits.
But Firefox is only provided as 32 bits binary for Windows from the standard download channel. You should try with Firefox 64 bits.
Probably your Opera version is 32 bits too...
I invite you to cross-check by installing a 32 bits browser (Firefox standard binaries) and a JDK 32 bits on Windows 7 64 bits. It should work.
Its likely that your Java path environmental variables weren't updated. Check out this link. Make sure its pointing java to the 7 exe.
