Several versions of java installed

hello all,
i have several versions of Java installed on my PC and its fast becoming a mess.
how can i completely remove all of them and only then install the latest jsdk?
thank you

Version conflicts are a rarity in Java. The latest JRE is usually utilised unless otherwise specified.
Only one JRE can be used at any one time by one program on Windows anyway. It does get crowded sometimes however - just uninstall as you would any other program with the Control Panel::Add/Remove Programs.
Personally I keep all of my JREs on my machine for several reasons and I recommend keeping it this way.

I've 2 versions of Java installed! How can I uninstall Apple's Java 6?

This is where I'm at
* Updated from Snow Leopard to Mountain Lion
* Installed Oracle Java 7 update 7 dmg
* Misread an out of date OS X Daily blog where I got this Terminal command java -version. It lead me to think Java 7 wasn't installed
* Installed Apple Java 6 via the Java Prefs app. Thought this would somehow lead to a Java 7 upgrade along the way.
* Realised that Oracle Java 7 was installed fine the first time, but java -version doesn't work with it !!
* Now I have 2 versions of Java installed!
* I reinstalled Java 7 (this time using 7 update 10) hoping it would remove Apple's Java 6 but it didn't remove it.
*For some reason too the old Java Prefs app has been automatically deleted too, so I can't switch Apple Java 6 off.
Confirmation that I have 2 Java versions installed
If I type the terminal command java -version it says I have Apple Java 6 installed.
If I open LibreOffice/Preferences/Java it says I have Apple Java 6 installed.
If I open Play Station 3 Media Server it says it's using Apple Java 6.
If I open some other Java .jar apps like JOSM it says it's using Oracle Java 7
Oracle has a FAQ that recomnds deleteing old versions of Java, but very helpfully only gives instructions for Windows.
How can I uninstall Apple's Java 6?
Thanks

Reinstall the OS … meaning reinstall OS X?! Is that not a bit over the top?
>"BTW, do note that all you're really doing is changing the Java Runtime Environment component and not Java."
At this stage I don't have a clue what I doing !!
In the past week and a half I have had a belly-full of Java name permutations. What kind of sick, twisted mind came up with Java naming scheme: Just take the word Java and append two or three letters to it using every permutation possible, throw in a few numbers for good measure, and then when discussing it just use the generic term Java… that'll really catch 'em out.
…Java SE, Jave RE, Java JDK,Java Platform, Apple Java 6, Oracle Java 7, Java 1.6.0_27, Java 1.7.0_10, Java 6, Java 7, ….. not to mention Java FX, Java DB, Java ME, Java EE, Java DST…

Java applets won't load, have latest version of java installed, have removed all old versions from the hard drive, java console not working in firefox, any suggestions please ?

java applets will not load,
i have run the java test page & i have the latest version installed.
have removed all old versions of java from my hard drive & restarted the computer.
i have checked that java is enabled in the plug-ins and it is with version se 6 u22, also something called java development toolkit 6.0.220.4 np runtime script plug-in library for java (tm) deploy.
if i click on java console in tolls nothing happens

Hi,
You might want to look in your control panel for 'Java' icon. It should give you an option to enable java plugin into your browser. Let me know if you still face the issue.
Thanks!

How do i fix the message to update java deployment kit when I already have the lastest version of java installed?

I keep getting a message that "An important update is available for Java Deployment Toolkit 7.0.400.43". I click on "Update Now" and I get taken to the Mozilla Plug-in check page. A brief message shows at the top of the page that tells me some plugins are out of date and then disappears. The plugin checks show all plugins are up to date. I have uninstalled/reinstalled Java more than once and run a registry cleaner, but once I install Java the same messages appear. I am on a Windows XP machine and I am running an older version of Firefox (9.0) because addons for some of my other software don't work with newer versions of firefox. Can I get rid of the message or do I have to live with it because I use an older version of firefox?

Please update to Firefox 23.0.1 IMMEDIATELY. Old versions are extremely vulnerable to security issues, and all your add-ons should work if they work in Firefox 10 anyway.

More than one version on java installed?

I am having difficulty running a simple 'hello world' program on my machine. I have installed jdk1.3 and I can compile a .java file with no errors but when I try to run it I get the following error: Exception in thread "main" java.lang.NoClassDefFoundError: FileName
This seems to imply that I am using the wrong file name (as I get the same error if I deliberately misspell the filename), but I'm not. I think that there may have been an earlier version of the java sdk (122) on this machine previously - there is an empty jdk122\bin folder. Could this trace of an earlier installation be giving me problems?

No, your classpath is not correct. Search the forums for NoClassDefFoundError, this question is asked very frequently.

HT5045 Is there a way to install older versions of Java, like Java 6 Update 26 on Mac OS X 10.7 ?

We have an application that worked fine on Java 6 Update 26. Update 29 broke the application. Even though we have fixed the problem, for people using older versions of the application, there is no recourse, if they have upgraded their OS to 10.7. So, is there a way to install Java 6 Update 26 on Mac OS X 10.7 ?

Hello,
I have a client that just started working remotely and needs to do payroll via her Mac OS X 10.7.5 system via a web browser. The payroll system appears to be ADP/Kronos as far as I can tell. We first tried using Safari and it said the plugin was missing so we downloaded the latest Java and installed. When we tried to run it dumped the following error. (see below)
At this point we decided to try Firefox and rather than a dump we found the message Java 1.6.0_07 required.
At this point we went hunting for an older version of Java and did find one only to be told if was specifically for OS X 10.5.x. My client is running OS X 10.7.5.
I have other clients running Windows that have multiple (older) versions of Java installed including 4, 5 and 6 all on one machine so I'm not sure if this is possible on Mac OS X or not.
Note I am not in charge of the payroll system and have no way of updating that side of things. I may recommend that my client contact her internal Help Desk or revert to using a Windows based system as I know for sure that would be capable of handling these requirements.
Thanks, Jason

Sneak Preview sp11 Slim Java install hangs on J2EE Startup

I looked around at the other instances of this type of error, but they seemed to be slightly different issues (or at least, at differenst steps). Tried what helped them anyway, though it didn't really help.
My install hangs at the Start J2EE Engine (step 21 of 24 normally). It seems to retry every 20 seconds, but never gets anywhere and eventually pops up an error. I've retried from there, stopped and restarted, wiped out the whole install and tried again. I've repeated this for several versions of Java, the latest being the 1.4.2_08 version. They all get to the same part and die.
This is the error right before it gets into full swing on the waiting/retrying.

My os is XP, and seems to meet the min system requirements for the slim version.
Any ideas on getting over this hump?
Edit: After talking with someone at the ICC, turns out pretty much that I shouldn't be trying to install the slim version. So, time to go find a machine that can handle the normal Java install.
Message was edited by: Cortney Denver

Looking around at other experiences as well as my own several attempts (just tried an installation on XP several times this evening), none of this stuff works and SAP could not possibly care less. A clearly deeply flawed installation has been sitting around for 5 months now... one is left to wonder what highly specific conditions are required for success.
Good luck to you... I give up.

Java install problem under redhat 9

I download rpm and install it under redhat 9. I can compile program (the class file is generated) but can not run it.
I checked the path and see /usr/java/j2sdk1.4.2_04. WHen I check the version, it tell me version "1.3.1". It soulds like I have 2 different version of java installed. How can I solve this problem?
Thanks

Probably not a mix up. Try to update your path wirh the path to the bin directory of the java version you want to use. Something like :
export PATH=/usr/java/j2sdk1.4.2_04/bin:$PATH

Help!! Two Apps running 2 different versions of Java 1.3 &1.4

I work in the IT dept for a IBM service provider. Recently IBM has changed their web quoting tools. The main config tool runs on Java 1.3.1_08 and their new maintenance quoting tool runs on 1.4.1_2.
I have both versions of java installed and neither program will work. When I try to launch the maintenance tool that runs 1.4.1_2. The web start screen appears and then disappears and my processor performance maxes out at 100%. I have to control alt delete and then end task. When trying to run the main quoting tool , the Java applet never starts. I have tried to get technical support from IBM but they keep pushing it back to me stating that it is Java, or the machine, and they do not support that. The machine has been freshly imaged with Windows XP Professional, the system is a p3, 1.2GhZ with 512MB ram. Is there a way to make these programs work in the same environment? Thanks.

This sounds quite a bit like the problem I've been having. So far the most informative thread I've seen is here: http://forum.java.sun.com/thread.jsp?forum=32&thread=363105&tstart=0&trange=15 , but the fact remains that there are a lot more people with questions than answers on this one.

I am trying to use a website that requires that my computer have the latest version of Java, which I have updated and installed Java 7 Update 51 (64-bit), however Firefox does not recognize that I even have Java on my computer. My computer is 64-bit
When I run "Verify Java Version" it show nothing is installed... but it is, I know that for a fact because it shows in my "Control Panel/Programs/Programs and Features".
When I go back to the Java Download page, the following message is visible:
"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."
My question is this:
Is there a way to change my Firefox browser from 32-bit to 64-bit.... because it appears that this is way Java is not functioning properly?

Firefox needs 32-bit plugins, so you'll need to install 32-bit Java for Firefox.
No, you can't change Firefox from 32-bt to 64-bit. There is a Nightly 64-bit version (alpha) of Firefox, but it is used only to test for regressions until development is resumed.

Can't install Adobe Flashplayer 11. Uninstalled old version. enabled Java. Allowed cookies. Install button grey.

Can anyone help me with this problem of installing Adobe Flashdrive 11, the latest version ? I'm bashing my head against the wall. Started when iPhoto would not load to Facebook and was advised it could be Flashplayer update after troubleshooting other options including deleting extraneous iPhoto files. I uninstalled older version, enabled Java, allowed cookies, downloaded installer but when I try to download it, the install button is grey and won't work. (This is, coindcidentally the same problem that suddenly began today with iPhoto which always worked fine before....grey button for "publish") It is ALWAYS a problem installing Adobe anything, and usually this same problem. All my software updates are current. Now I have NO Flashplayer and can't use YouTube at all, much less iPhoto.

Also, sounds like others are having this problem. Read other posts, didn't find an answer. OBVIOUSLY did not solve my problem. No delete ? First time here, sorry.
