Safari on Win7 -- Java not detected

I am trying to use Safari on a Win7 box to attend a WebEx meeting.
The WebEx Java client works on IE (so Java in installed on the machine).
However, when I try to launch the WebEx Java app from within Safari, I get an error of "WebEx Client Page tried to load Java content but Java is not available or installed"
I have 'Java enabled' checked in the Safari preferences.
I re-installed Java from Oracle and restarted the browser, but nothing changed.
Anyone know how to get Safari working on Win7 to support using Java apps?
Thanks in advance,
Charlie

The solution was actually very simple - I just needed to enable Java in the Safari Security Preferences!

Java not detected even though installed?

I'm trying to access a web based VPN client. When I go to the necessary website I get 'Java not detected or installed. Cisco Secure Desktop requires Java to be present and configured on your desktop.' I definitely have Java, so how do I make it detectable?

The solution was actually very simple - I just needed to enable Java in the Safari Security Preferences!

What does "java not detected" mean and what should I do about it?

I am a teacher who teaches partly online. While trying to use Screen Recorder in Kaltura Media Space to record my desktop with audio voiceover, I encountered this message in red and was not able to use this device? I am not sure what the message means or how to fix this. I am using MacOS 10.9.1 and Safari. MediaSpace is provided by our school system, so I am not able to use my iPad to do this.

Do you have a Java Preference Pane in System Preferences? if not, Java isn't installed and from your description, it sounds like it may be required. You can also try running this Java Test.

Java not detected in redhat 5 linux firefox

I have installed the latest java 1.6_24 version using rpm on linux redhat machine. "java -version" works OK, I have the link:
libjavaplugin_oji.so -> /usr/java/jre1.6.0_24/plugin/i386/ns7/libjavaplugin_oji.so
Also:
/usr/bin/java -> /etc/alternatives/java
/etc/alternatives/java -> /usr/java/jre1.6.0_24/bin/java
In the past install (java 1.4) there where also some references to "jvm" but these don't exist in 1.6 version.
Must be something else missing..

libjavaplugin_oji.so is the old classic Java plugin. For Firefox 3.6.x you need the Next Generation Java plugin (libnpjp2.so)

Since updating to Firefox 3.6.15, I can no longer print coupons from SmartSource. The error message is that Java is not detected. The check box is longer showing in the Options/Content of this version of Firefox, so I can not enable it.

Satellite M30x + Win7 : DVD's not detected by the CD/DVD drive

Hi,
I'm using a M30x since 2004 with its CD/DVD drive Mat****a DVD-RAM UJ-831 S.
When I was using Windows XP, I never had problems to read or write on CD, CD-R, DVD, DVD-R or DVD-RW. But recently i have installed windows seven, and since this day the drive doesn't want to recognize DVD's. I still can read and burn CD's and CD-R's. I'm trying to burn the same blank DVD-+/R/RW as before but the drive don't want to detect them. The ones I already have burn aren't detected either.
My computer say that the CD/DVD drive work correctly and that the drivers are updated.
I have tried to clean the lens but nothing have changed. And I wanted to reinstall the drivers but I couldn't found them for windows seven.
Thanks for the help.

At first I must say that this old notebook is definitely not designed and not supported for Win7 so if Win7 works well you are really lucky guy. Win7 s not supported and drivers dont exist so dont spent your time searching them on the net.
I dont know if described issue has anything to do with Win7 or not but fact is that lens position for CD medias and DVD medias is different and, generally speaking, when there is problem with reading one of these medias it can be problem with lens calibration what means optical disc drive is defective.
You can test it one more time if you install WXP recovery image and check if this will work again.
Other way I don't think there is anything you can do about it.
BTW: which burning application do you use?

Hi, I got a virus that does not let me use Safari. I downloaded an av from the app.store but it did not detect anything. I am thinking in formatting the HD. How can I do it and will I lose?

CRIO-9073 is not detected in "Measurement & Automation Explorer" on my Win7(64-bit) system. Please help.

When I connect cRIO-9073 with my Win7(64-bit) laptop via ETHERNET cable, it is not detected in "Measurement & Automation Explorer".
I have LabVIEW-2011 installed on my laptop.
Please help..
Thank you....

Is this a new controller? First time connecting? Does the controller have an IP address set?
The Windows firewall may interfere with detecting a cRIO if it's the first time. Make sure your fire wall is off and try MAX again.

"JAVA_HOME" is set.
"Path" contains path to jre & jdk (i was try any varyations also with '\bin' subfolders).
javac run from any location.
The registry has all nessesary mentions jre & jdk.
But, nevertheless, applications does not detect jre.
Please help! Any suggestions are welcome.

Ipad Not Detecting Win7

My new Ipad2 is not detecting inside Itunes, and my Iphone4 does. Have tried multiple usb cords and all same outcome.. This is the first time i've tried connecting the Ipad to my laptop, and again, all my other devices are detected within Itunes (My 2 iphone 4's and 2 Ipod touch devices)
Hope theres an easy fix, thanks!

Same situation. My Ipad2 is undetected in last iTunes version (10.6.0.40) in my desktop (Windows XP SP 3 32 bits). Same cable get to detect my iPhone 4S. I have tried everything (drivers, reboot, iPad reboot) that was posted in many forums. Many services shoud be active (Bonjour, ...), but nothing works. I've got connect iPad using my laptop Windows 7 64 bits with a fresh iTunes setup.
I advise you to do the same. It's easy transfer your movie, apps and songs, because you can have until 5 authorized computers with same songs, movies and apps.

Windows 7 Pro x64 does not detect HP Mobile Data Protection Sensor (accelerometer)

Hello there.
I installed win7pro x64 yesterday and already came across a serious problem that makes my way of using the notebook a bit dangerous for my precious data.
When I was working on HP-branded Vista 32bit (from recovery partition etc), there was a device called HP Mobile Data Protection Sensor together with HP ProtectSmart (or Protect Smart) software. In other words, the HDD accelerometer that parks HDD's heads when it "feels" it's falling or something, and software for it. It worked brilliantly.
Until I decided to install Win7... Then, surprisingly after a driver-install failure and taking a look at the Device Manager I noticed that there's no such device! I checked it three times, looked at every device's property, even reinstalled Vista 32bit back - it showed again - and installed Win7 - not detected again. There's nothing that has Device ID's HPQ004! I remember people saying that after fresh Windows install, there were 6 unknown devices or more. I had only 5. [Fingerprint device, 3x MemCard reader and IR receiver]. There was no accelerometer... Also, when I try to install the drivers/software, the windows pops up:
ProtectSmart Hard Drive Protection: with text Property.AccelerometerNotPresent
and then another one saying something like Features were not installed because of installation error or unsupported feature.
So now I'm stuck with a notebook that is unsafe to travel with, because the disk is no longer protected
I already installed all the drivers available from HP page, even downloaded newest ones from Intel (chipset) etc.
Is there a solution to this? Has anyone else encountered this problem?
Windows 7 is officially out and available as RTM version, not beta, so I think HP should open support for it and release new drivers for win7! And most importantly, fix this issue ...
This question was solved.
View Solution.

Well, thanks to myself, I fixed it. After some thinking I remembered that ACPI = BIOS-related. It appears that there is a problem with the newest (F16) BIOS.
F.16 changelog is below:
Version: F.16 A (26 May 2009) Fixes
Updates the Intel MRC Code to version 2.7.
Updates the Intel AHCI OP ROM to version iSrc 1.20_E.0012 11252008.
Updates the BIOS to support Microsoft Windows Vista Operating Systems with Service Pack 2 (SP2).
I went back to version F.14 and... boom! New (unknown) device found And guess what, it's ACPI/HPQ0004... So now my HDD is protected again ^^ yay!
I don't know which of these changes cause that, but it looks that that can be fixed.
I'll go back to F.16 again to see if the device will disappear and then contact HP support on that case.
EDIT: Well, F.16 breaks things again, so it's definetely a BIOS problem. Thanks for... umm... well... at least spread the word, guys I hope this helps if someone has the same problem.

VideoFormat vidformat = new VideoFormat(VideoFormat.YUV);
Vector devices = CaptureDeviceManager.getDeviceList(vidformat);
CaptureDeviceInfo di = null;
if (devices.size() > 0) di = (CaptureDeviceInfo) devices.elementAt(0);
else {
/* I got exception here */
JOptionPane.showMessageDialog(parent,
"Your camera is not connected", "No webcam found", JOptionPane.WARNING_MESSAGE);
return;
try {
ml = di.getLocator();
setMainCamSource(Manager.createDataSource(ml));

Mouse clicks not detected on JTabbedPane

Hi all,
I have a JPanel placed inside a JTabbedPane. I want to double-click on the JPanel and bring up a JDialog. This works fine if the JPanel is not in a JTabbedPane, but if it is on a JTabbedPane, then the mouse clicks are not detected. I'd greatly appreciate any help you can give me.

Here is a sample program that seems to work:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
public class TestInternalFrame extends JFrame
     public TestInternalFrame()
          JDesktopPane desktop = new JDesktopPane();
          setContentPane( desktop );
          JInternalFrame internal = new JInternalFrame( "Internal Frame" );
          desktop.add( internal );
          internal.setLocation( 50, 50 );
          internal.setSize( 300, 300 );
          internal.setVisible( true );
          JTabbedPane tabbedPane = new JTabbedPane();
          internal.getContentPane().add(tabbedPane);
          tabbedPane.setPreferredSize( new Dimension(300, 200) );
          JPanel panel = new JPanel();

Safari 5.1.2 not updating on SUS (Software Update Server) (Lion Server 10.7)

If you see the screenshot attached, you can see that the Software Update Server has downloaded Safari 5.1.2
However, the clients connecting to this software update server have Safari 5.1.1 and when I check for udpates it does not detect that the update for 5.1.2 is available.
When I click on Choose Version, it shows two versions of 5.1.2, but I'm unable to choose the other version of 5.1.2 to see if it works. (see 2nd screenshot)
Any ideas what I'm doing wrong and how to fix?
Thanks in advance for any advice.
