Java won't run

I think I may have got a virus on my computer. My java won't run at all. When I put on the Flashback Checker it said it was clear but I still can't run java or update it. I'm on an OSX so the new updates won't go either. I'd really like to run java programs

I went to about this Mac. Do you know where I can download java?
It came with 10.5.8 and is updated using Software Update.
All you need to do is make certain it's enabled in both Java Preferences (found in /Applications/Utilities/) and in your browser preferences.

Java won't run after latest update

I just installed the latest update for Mountain Lion and now my java won't run. I have tried all of the hints from Java's site and am stumped.
Any ideas?

This explains why. You need to download the latest Java from Oracle's site.

Java won't run on my OSX 10.7.5 can anyone help?

I have done EVERYTHING to get the latest version of Java to run. Java is "running" when I check it in system preferences, I have it enabled in my browser but when I return to Java, it doesn't detect it. I have restarted my computer and still nothing. Help???

Run through the steps listed in HT5559: http://support.apple.com/kb/ht5559
This is take you back to Java SE 6 that Apple developed and has helped me with many of todays Java issues. It is not going to mess anything up and you can always try to re-install the latest version again if you want to try a newer version, but this should get you going on whatever you are trying to do for now.

Java Won't run on AOL browser

AOL has told me that they pull from the internet explorer, however I am unable to run the Java Runtime on AOL, therefore I have to use the internent explorer, which I do not like. I am unable to play games on AOL, it's not letting the Applets load. Does anyone know what is going on. I have reinstalled AOL, made sure my security settings are correct. An AOL does not have an answer either.

http://java.sun.com/j2se/1.3/download.html
After you download the jre file click on it to install it. I'm not sure why AOL isn't registering and the internet explorer is.
Try putting this into your autoexec.bat file (if your running on windows operating system).
set classpath=C:\ProgramFiles\JavaSoft\JRE\1.3.1\bin;%PATH%
Make sure the file path is correct. It's the path to the java.exe file. This ensures programs that use java.exe file to find it.
You have to restart your computer after changing the autoexec file for it to register.
Good Luck!

Java won't run in Safari, FF, or any other browser

I need to use a lot of Java pages for work. They used to function fine with Safari and Firefox, but now, neither browser can access any page with Java content on it. Firefox gives me a dreaded "red X" with the error message that "Java Applet notloaded" and Safari actually hangs on the page that leads to the page with Java.
Any suggestions? I'm desperate!
Mini Mac OS X (10.4.8)

Welcome to Apple Discussions
The cache files for Java may need to be cleared.
Go to your Applications/Utilities/Java and select Java 1.4.2 Plugin Settings.app Double click. Select Cache panel. Then "empty cache".
Also, in the same Java folder double click on J2SE 5.0>Java Preferences.app
The panel ought to look like this:
If it doesn't make corrections as needed. Note the position of J2SE 5.0 and Java 1.4.2. If they are reversed, drag one to the correct position.
Restart the system. See if that helps.
Post back and let me know if that brought Java back on line.

Java won't run / can't find file

i'm new to using java so any help is usefull
the files are in the same directory, they are all named correctly. do i have to compile the java class file first or can i just point to it using a html as i am doing?
this is the error message:
load: class Scribble.class not found.
java.lang.ClassNotFoundException: java.io.FileNotFoundException: C:\JAVA\Scribble\class.class (The system cannot find the path specified)
i see the CLASS.CLASS at the end but thats not the path the file is located in. its making its own path

You're probably giving a class file name where a class name is expected.
So if you say "Scribble.class" (a file name) in a place where a class name is needed, then the JVM will look for the class file, which (given that class name) would be "class.class" in a package named "Scribble".
Try removing the ".class" and try again.

Java applets won't run on Safari???

I have reinstalled Java twice, and it still won't run any Java applets. It just sits there with the cup logo and the arrow on either side. It works fine on Firefox but not Safari. Help?

Hello
I'm piggy backing on this thread because I too have had problems with Java and Safari
Java runs fine for me in Firefox, however.
I went to a federal website
https://blrscr3.egs-seg.gc.ca/gol-ged/gov/browserdetection/BrowserCheck.html
that uses java and received this message
" Java applet unable to load
To use this service, you must either install a recent version of the Sun JVM or enable "Scripting of Java applets" if it has been disabled."
so i looked for an update and have downloaded and installed release 6, (at least, it said that it was installed, but have never been able to figure out where)
when I check Java preferences, the choices are J2SE 1.4.2 or J2SE 5, and when I've switched to 1.4.2 I still have no luck.
When i run firefox, i get the java console opening, but it doesn't open with safari, and I can't find the option for this to turn on in safari
i have restarted both safari and my computer and no luck. I have repaired permissions and no changes have taken place.
Any more suggestions?
(thank you, by the way)

My accounts program won't run without legacy Java SE6 runtime since I upgraded to OS x Yosemite but I can't download it

My "Solar" accounts program won't run without "legacy Java SE6 runtime" since I upgraded my iMac desktop to OS x Yosemite but I can't download it, nothing happens when you click on the link to apple support

Okay, I'm not a Genius, but, I'm smarter than the one I spoke to at the Apple Store.They told me that they couldn't help me with Legacy Java SE6 Runtime. Adobe has the worst support in the industry so don't call them.
If you have a Time Machine backup, go to one that pre dates your install of Yosemite. Go to the System/Library/Java and drag copy the folder to your internal hard disk. Now you will need the Administrator password. Once copied, drag the old Java folder into your System/Library folder and when asked to replace, click OK. Restart your Mac and you will have use of your software that requires Legacy Java SE6 Runtime.
I'm totally done with Apple since they are trying to box me into a corner. Have fun kids.

Java JDK 7 u17 won't install and Eclipse won't run past boot logo.

Java JDK 7 u17 won't install and Eclipse won't run past boot logo. Eclipse Classic used to work fine for awhile. I haven't used it for a month or two and tried to boot it, Eclipse won't run past boot logo. It looks like JDK is not even there anymore. JDK won't install successfully. I have Mac OS X 10.8.3.
I tried removing Java, re-download JDK multiple times.. same results.

Paul Adare is correct in saying that you cannot "upgrade" from 32-bit to 64-bit. You can, however, backup your files and reload them onto your PC.
Given that you are able to boot Windows 7 after the failure to install Windows 10 Technical Preview, it is apparent that you are not formatting the drive during your clean installation. There are a number of potential issues an existing configuration can
cause, such as preventing Windows Setup from registering boot files, modifying partitions, or moving an existing installation and data to the windows.old folder. I would recommend removing the partitions from your drive (note: this will erase any data remaining
on the hard disk) during installation to ensure that Windows Setup has a fresh hard drive to install to. If you continue to experience errors, two other factors to take into consideration are:
Does your system use a storage controller that requires loading a driver during Windows Setup?
Is the hardware malfunctioning? Do the hard disk and memory pass testing software like Windows Memory Diagnostic or chkdsk?

Java runtime environement won't run

I have a Lenovo T430 Thinkpad. I have Java (7u67) installed. The applet will run through the browser (firefox), but JRE won't run through the command line. I have a program that uses Java, but that program won't run because JRE won't run. I have uninstalled and reinstalled with no luck. I'm running Windows 7 enterprise. Any help would be appreciated.

ic, thanks for the clarification.
In my classpath, I didn't include the path to java's core classes/packages (java.awt, javax.swing, etc.), how would it know?
The above questions arise when I get an error running the jar executable. In this jar files, I included all the classes (but not the nttp and the core java packages). It complains that nttp is not found. I guess it knows where the core java classes but beside those, I need to include any other packages/classes within the jar file itself?

Java FX apps won't run on the browser with Linux

This is my current system configuration:
Opensuse 12.3 x64
Nvidia Gefore 9600gt with Proprietary drivers
Tried both the Oracle Java 7u45 and 7u51 (Installed according to: SDB:Installing Java - openSUSE)
Google Chrome and Firefox (Latest versions for both)
I am not able to run any Java FX browser app. When the app starts loading, i just get a gray box inside the browser screen. I've reproduced this with the JavaFX Ensemble sample app as well as my own apps. This is the exception i get on the Java Console when trying to load the Ensemble app:

After you download the jre file click on it to install it. I'm not sure why AOL isn't registering and the internet explorer is.
Try putting this into your autoexec.bat file (if your running on windows operating system).
set classpath=C:\ProgramFiles\JavaSoft\JRE\1.3.1\bin;%PATH%
Make sure the file path is correct. It's the path to the java.exe file. This ensures programs that use java.exe file to find it.
You have to restart your computer after changing the autoexec file for it to register.
Good Luck!
