HT4883 java doesn't work

I installed Java manually from the apple web site. however when I open a web page that runs java application the page doesn't work. I had trouble initially intalling java automatically, I got a dialog box saying that I was not connected to the network. How can I get run Java correctly in my computer?

When you use Google Chrome (uses it's own Java), you get this message in a separate window:
The requested resource (/finans/header.jsp) is not available.
Also tried it with Internet Explorer 8 in Windows XP. It doesn't works the same as Safari there:

HT1338 java doesn't work and there is no update (via apple) available.

Now running mountain lion. Unfortunately java doesn't work and there is no update (via apple) available. What do I do?

Open Terminal (Applications/Utilities/Terminal.app) and type
java -version
press 'return' on the keyboard.
Either
1. You get a version number for Java, in which case enable Java in
Applications/Utilities/Java Preferences.app
Or
2. You get an installer window pop up. After clicking through and installing that, enable Java as in 1. above.

Java doesn't work on safari / xp

Downloaded the latest Safari, 5.1.7, for Windows XP
Downloaded the latest Java, JRE as well as tried JDK, 7.04 and configured for IE and Safari.
Java.com test works on IE, but on Safari, refers to
C:\Program Files\Oracle\JavaFX 2.1 Runtime\bin\server\jvm.dll
There is no server directory, nor any jvm.dll anywhere in the Oracle install.
What's wrong??
Help!

Java doesn't work on Firefox

Java works in Internet Explorer but doesn't work in FireFox.
My installed Java-related programs are:

Java doesn't work in mozilla 0.9.3

hello,
I just installed the mozilla 0.9.3 but the java plugin doesn't work. It comes with the Java2. It has the sym-link in the plugins directory but still doesn't work?? I tried looking in the mozilla website but couldn't find an answer to my question.
I also have loaded on the same machine netscape 4.78. I tried loading the JRE 1.3.1_01, but that also doesn't work. I'm sure the sym-links are in the correct places according to the Sun installation instructions......
What is causing this???
thank you,
Oskar

I had the exact same problem with mozilla 0.9.3 and using the blackdown 1.3.1 java plugin on Mandrake Linux 7.2. Then I formatted my hard drive ( not because of this problem...ha ha ) and when i installed mozilla i got the plugin to work. What i did was, create the symbolic link ( as suggested in the installation instructions ), then started mozilla, then shut mozilla down, then started mozilla for a second time ( and the java plugin then showed up in the 'about plugins' page), then i viewed a web page with an applet and moziila crashed.....ha ha....and from then on it has worked perfectly.........i cant remember where i read about this bug..(sorry)...
anyway, to summarise you need to restart mozilla twice after making the symbolic link before viewing a page containing a Java applet. (i dont know whether you will have to reinstall mozilla to get this to work ?..seeing as you have already tried this once? ) Good luck ( sorry if this reply is a bit of a mess !!!)

Java doesn't work at all

I might have screwed something up...
but whenever I try to upload pictures on facebook... doesn't work..
any thing Java doesn't work

Hi... did you do something you should tell us about?
How much Free Space do you have on your Hard Drive?
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.
The usual reason why updates fail or mess things up, or things don't load/run, is if Permissions are not fixed before & after every update, with a reboot... you may get a partial update when the installer finds it doesn't have Permissions to change one obscure little part of the OS, leaving you with a mix of OS versions.
Some people get away without Repairing Permissions for years, some for only days.
If Permissions are wrong before applying an update, you could get mixed OS versions, if Directory is the slightest messed up, who knows!
If many Permission are repaired, or any Directory errors are found, you may need to re-apply some the latest/biggest updates again, or even do an A&I if you have enough free disk space.
The combo update for PowerPC-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateppc.html
The combo update for Intel-based Macs...
http://www.apple.com/support/downloads/macosx10411comboupdateintel.html
Repair Permissions before & after re-install, then reboot again each time.
If all the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.
I only use Software Update to see what is needed, then get them for real via...
http://www.apple.com/support/downloads/
That way I can wait a week or so, check the forums for potential problems, and get Permissions & such in order before installing.
If it appears to be time for An Archive & Install, which gives you a new OS, but can preserve all your files, APPs, pics, music, settings, etc., as long as you have plenty of free disk space...

C'mon - a stack trace, an error message, a description of what you have versus what you want. Anything than postnig a mess of code, sitting back, and saying "Please kindly try to help me." That passiveness tends to not do well here.

MySQL + Java doesn't work

I've been trying to get a connection using MySQL and Java without luck, I've been messing with every solution I have found in google without luck. It worked the last time I used mysql + java a few months ago (in Ubuntu) but now I can't even get a connection.
MySQL works with PHP, MySQL Administrator and CLI but I just can't get it to work with Java.
Has anybody been able to run Java applications that use JDBC + MySQL in Arch?
The stack trace I get is like the following and it changes a little bit if I use different versions of the Connector
java.sql.SQLException: Server connection failure during transaction.

FTP server in java doesn't work well at win os in some status.Why?

As we know,FTP server in java used to use "BufferedOutputStream(socket.getOutputStream())" to complete data transfer.
socket.getOutputStream() returns SocketOutputStream, and SocketOutputStream use native method:socketWrite0 to transfer data.
I writted a FTP server in java that runs at win XP or win 2003 server. FTP client download file through internet,and when file size is large(for example, 5M),the download is failure. But I changed FTP server in C++,the download is ok. These PCs have multi network card commonly.
In the first instance,I thinked my programm may be written wrong. But I have used CrossFTP and DanoFTP at sourceforge.net, they failed too.
I have compared the source code of these FTP server and they are same in data transfer.
There are another strange phenomenon.FTP server at some PC works well. For example,when I install FTP server at another PC.So I think that it is not link problem,and may be relate with PC's configuration?
Any help appreciate.

Win XP(sp2) and win 2003 server all have happened. Version of JDK is 6u2. I have doubted with version of JDK, and I changed to JDK 6u10 but problem is same.
By the way, FTP server in C++ work well on these problem machine.
I think the problem is related with configuration of machine(hardware or software), but I want to know where and why.
Thanks for any help.

Javac *\*.java doesn't work for me?

D:\Apps\Eclipse\eclipse\Workspace>javac *\*.java
error: cannot read: *\*.java
1 errorI'm probably missing something obvious here, but what is it? Also, dir /s works for me; what does javac work on when doing recursion?

I got the impression that javac was recursive (in fact, I think that I've seen those words precisely) outside of .jars, which I don't use - if I get one, I just extract it. I'll use a third-party compiler if it comes to that, but I think that javac ought to work.
For the record, I don't have a CLASSPATH Environment Variable (though if I did, it would just be a case of making sure that . is on it). I think that having one just overwrites the default one, which is ".".
Does javac *\*.java work on other machines? Do I just have the command wrong?

In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following:
/Library/Little Snitch

/Applications/VirusBarrier X6.app
/Applications/iAntiVirus/iAntiVirus.app
/Applications/avast!.app
/Applications/ClamXav.app
/Applications/HTTPScoop.app
/Applications/Packet Peeper.app
If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot.

Java doesn't work in proxy environment

I assume it's because of the "separate process" approach to running Java taken by Safari 5.1, but when my system is set to use a proxy, Java ceases to function in Java 5.1. If I then return to a non-proxy environment, Java works again. In the proxy environment I tried reinstalling Java and quitting and relaunching Safari, but no luck. Under the same conditions the same Java applets worked in Firefox 5.01 so I know Java was fine with the proxy itself, it's just that Safari 5.1 is somehow interfering with that or failing to set a parameter in the Java environment I would guess.
Tried to find a way to lodge a bug report but this is the best I could do.
Anyone else?
Cheers,
Matthew.

Sorry - I meant "in Safari 5.1" and I now see there have been other reports.

Java doesn't work on safari

Since I've installed the latest java version, my browser stop running Java plugin. I cannot access my bank account etc.
PS.: I already have unistalled the Java an installed again, twice; I shutted down my computer, I restarted the browser... And, YES, java is activated on preferences panel.
I don't know what to do anymore.
Sorry for my poor english!

How do I test whether Java is working on my computer?
You may see the words "Old versions of Java have been detected on your system." In that case, click on the button labeled "Free Java Download" to install or update the Oracle Java plugin. Make sure Java is enabled in your browser settings only when you need it, not all the time. Using Java may expose you to malware attack.
If you see a banner on the test page with the text "Inactive plug-in," click on it.
