JRE-6u22 Uninstall 250 Machines

Need to script an uninstall of 6u22 and reinstall 6u21 on 250 XP SP3 machines. Machines are used by filed Reps / not connected to Domain. Haven't been able to find the msi. Anyone know what file name / directory will trigger an uninstall?

I use psexec from Microsoft to uninstall Java when things don't go right:
psexec @d:\temp\working.txt MsiExec.exe /X{26A24AE4-039D-4CA4-87B4-2F83216022FF} /q

JRE Setup to Client machine on Intranet by using browser...

Hi everybody,
I have a problem about setting up JRE. If a client on the network wants to execute my client application, if there is no jre on the clent machine, the application try to connect java.sun.com for setting up JRE. If client machine has no internet connection, then the application cannot work. So my aim is to set up jre on the local server. For this, I reserched many times. But I cannot success. Becuase I dont know what is requirements for setting JRE b y using browser.
Thanks for help...

Hi
Part II of the [Java Plugin Developers Guide|http://java.sun.com/j2se/1.5.0/docs/guide/plugin/index.html] describes the deployment using IE.

Java JRE Manual Uninstall???

Java 1.6u7 was installed on my Windows XP machine, but became corrupted. I downloaded the new JRE 1.6u10 (slim vers.) and attempted to install. The install program informed me JRE was already installed, would I like to reinstall? When I click "yes" then I get a message, that that option is only available for installed programs...then the install program loops, asking again if I would like to reinstall...then quits. Same result exactly with the Full install (15mb) version. No matter what I do, I get the same loopy message..."That program is installed [no it is not, anymore] Do you want to reinstall?" [yes] "Operation is only available for installed programs" Loop, loop (twice).
I've spent a lot of time searching for any help on a manual uninstall of Java through google, all to no avail. No one seems to have a definitive method to MANUALLY fully remove the old Java, in order to successfully install the new.
YES, I've uninstalled it through Add/Remove.
YES, I've tried the control panel Java link (it's now gone)
YES I've used the Windows Install cleanup utility (Java is no longer there).
YES I've used regedit and eliminated everything with "Java" in it. Yes, I've repeatedly searched both filenames, and within files and deleted files with JAVA in them. Yet EVERY SINGLE TIME I try to install, the very same loopy message appears, not allowing me to install.
All I'd like to do, is to successfully do a new install--yet the install program will not allow it.

I am the author of the original plea, SIMPLY LOOKING for a MANUAL UNINSTALL procedure for a corrupted Java JRE install. (Sun's system somehow won't allow me to login under my origianal registration, so here I am again.)
Please NOTE: YES, I have already used the Windows install clean-up utility (several times), as described in the original post. Sun and Java products are not found by the Windows install clean-up utility.
The installer is the problem....it will not install, unless Java is uninstalled first, and the uninstall won't work unless it is installed. Loop, loop, loop....
I HAVE CORRUPTED INSTALL FILES SOMEWHERE, AND NO STANDARD/FAQ AUTOMATED METHOD WORKS.
All I need to know is: HOW DO I MANUALLY UNINSTALL JAVA JRE???

Two JREs in the same machine

Hi.,
I had problems with two different version of JRE.I have an applet that works well in JRE1.4. Now I had a different applet that will be working only on 1.2.x.Is it possible to switch the JREs depending on the context through the html(where the applets are embedded).I know through control panel we can change the JRE setting manually.

No - you have to adjust PATH and CLASSPATH, JAVA_HOME, etc environment variables to point to the desired version locations and libraries. If you have any other hard-coded locations/files/directories in your code that is version-specific, they'll also need changing.
This is most easily done by building a script (.bat file, etc) that would be run prior to the applet startup to adjust the machine environment and parameters.

How to find JRE Version on client machine

My client machine does not have any class file, they are running web pages on web Browser.
We have some specific plug-in based on JRE Versions (e.g. JRE 5 or JRE 6).
Also we do not have permission to run an applet on client machine as it�s a security concern.
We have following senerio
Application server on Machine-1
Web Server on Machine-2
Client on Machine-3
We need JRE version of Machine-3.
Please provide me a solution.
Thanks in advanced.

Old post but replying anyways so that the solution can be used for later
For Firefox/Mozilla/Netscape this can be done through javascript like below
     for (i=0; i<navigator.plugins.length; i++) {
     document.write(navigator.plugins.name);
     document.write("::::");
     document.write(navigator.plugins[i].filename);
     document.write("::::");
     document.write(navigator.plugins[i].description);
     document.write("<p>");
It prints out "Java Plug-in::::NPJava12.dll::::Java Plug-in 1.4.1_02 for Netscape Navigator (DLL Helper)"
from which the plug-in version can be found out
For IE :
     try{
          var obj= new ActiveXObject("WScript.Shell");
          if (obj!= null) {
//Version for the installed JRE
var ver = shell.regRead("HKEY_LOCAL_MACHINE\\Software\\JavaSoft\\Java\ Runtime\ Environment\\CurrentVersion");
          alert(ver);
     }catch(e){}

HT3275 how do you uninstall time machine on an external hard drive?

I am using a seagate hard drive and discovered that since using it my space on my macbook is depleting. Don't know where it went so i want to start over and regain my hard drive space and use the back up only to store music and Logic pro data! PLEASE HELP!!!

Well, this is not easily answered. You can shrink existing partitions in order to add additional ones. But in order to add space from one partition to another that can only be done by first removing the lower partition first. If that partition has data, then it will be lost. Unfortunately, Disk Utility cannot manipulate partitions in place. You need a third-party utility for that, iPartition 3.4.1.
Now with that said I'll pass on a bit of advice. Do not us your Time Machine backup drive for extra storage. External storage and backups should be kept on separate drives. I suggest you get a separate drive for your storage or Time Machine backups.
If you use Disk Utility you can shrink your Time Machine partition, but the only way to put that space in another partition is to first delete the storage partition, then recreate it with a larger capacity.

Jre-6u22 and greater breaks java webstart 1.4.2_11 application

I have a java web start application that actually worked in jre-6u18, but but definitely breaks with the jre-6u24 and I suspect any other jre greater than jre-6u21. The reason I suspect this is because a buddy of mine also experienced a similar issue and determined the breakage for him was between jre-6u21 and jre6-u22. I have tested in pristine environments and found breakage between jre-6u18 and jre-6u24 only because I do not presently have any of the versions in between to test.
Here are the details:
The JNLP file is configured to autodownload <j2se version="1.4.2_11*" href="http://java.sun.com/products/autodl/j2se" initial-heap-size="64m" max-heap-size="256m"/>
The launch attempt successfully downloads and installs this JRE in both 6u21 and 6u24.
It has been re-written from spec="1.0" to spec="1.5" and when I try to run it directly with the 1.4.2/javaws/javaws.exe it breaks with error stating that it is incompatible with spec="1.5" and to use a more up to date JVM.
When launched with jre-6u18 it installed the j2re1.4.2 and continued to fail to launch the application initially, but succeeded to launch it on a second attempt.
When launched with jre-6u24 it installed the j2re1.4.2 and ultimately failed on any consecutive attempt as well as the initial attempt usually with the following console output:
Java Web Start 1.6.0_24

     at java.util.ResourceBundle.getBundle(Unknown Source)
I compared the differences between the properties of the shortcuts that got created for the successful one and the unsuccessful one and they seem identical except for a minor cache difference as follows:
C:\WINDOWS\system32\javaws.exe -localfile "C:\Documents and Settings\smithj\Application Data\Sun\Java\Deployment\cache\6.0\39\3a08ece7-75d85e43"

Has anybody else experienced this type of breakage? Does anybody else have an answer, solution, or suggestion other than "upgrade your 1.4.2 app"?
thanks in advance.

Multiple JREs on the same machine

Hi all,
I face a problem with JREs on my compter. I had a java 6 so when I typed Java -version it shows everything is fine. Then I installed Java 4 as I needed to test a class, when I type java -version it shows java 4. I downloaded multiple java 6, but my computer still feels that it is still java4.
I don't know how to make my computer feels my new jre to run the new version of eclipse for example?
I tried from java under the control panel but this doesn't make any deffernece.
Any help, Thanks a lot,
amm

Assuming Windows.
When you install Java's JRE it places files in the directory Windows\system32 named java.exe, javvaw.exe, and javaws.exe. These files cause a certain Java version to be executed. The last version installed will overwrite the files placed there by earlier installs. Because the default system path of the computer lists this directory first in the pathlist, these files determine what Java version will be executed when you type a "naked " java command - ie, when you type "java <someClassName>."
To execute a different Java version, you need to type the full path to that version's java.exe, ie, "directory1\directory2\etc\java <someClassName>."
Each application (like Eclipse) has it's own rules and settings that will determine which version will be executed. You need to refer to the app's Help for that information.

Is there any way to detect if there 's an JRE installed on customer machine

I want to know if the customer has the JRE installed to make sure that my program can run.So the problem come,how can I know that.Someone told me to use
a command like "java -version",which seemed reasonable.In that way,i should write a bat file do that.This file will detect if there is an JRE installed,if there is get the version of the JRE and compare with the available JRE of my program,but if not,connect to the offical site to download.It is really hard for me to do that bat file.I am just a new programer without any experience.So I really appreciate if someone give me some advice.Sorry,my english is so bad.I am waithing for the help.

          catch ( IOException e )

Yes, of course that does, when Java is already installed, of course. The question here was how to determine if it is installed, at all. And, that will also only give you the version of the Java currently being used, of course, and not, as I pointed out in that quoted post, not necessarily the highest version installed on the system.
Please make your posts applicable.

With 250+ machines on our school network, is there a way to turn on "clear history when firefox closes" (cache setting only) by modifying a registry key or file?

I need a way to turn ON the clearing of the cache programatically within a logon script. Kids are not clearing the cache and the roaming profiles on the Windows XP and Windows 7 machines are getting way too big to be moved across the network on every logon and logoff. Otherwise we will have to remove Firefox, which I do not want to do, nor do most of the people in the school :)

There have been some threads here about large-scale deployment, but I don't know whether they would help after Firefox has been installed.
Random thought:
I suspect (but haven't checked) that changing the "Clear Recent History" options would add corresponding entries to prefs.js in the user's profile folder. (These usually are added during Firefox shut-down.) That's just a plain text file and you could append to it by a variety of means.
It might be possible to use a VBScript during logon to update that file before the user starts Firefox. The script would have to detect the random folder name(s) in order to make the update.

Can I deregister the JRE- without uninstalling

Dear List,
I was wondering if there was a elegant and quick way of deregistering the JRE, so that
browsers like my IE and NETSCAPE will be in affect without java.

Open the Java Plug-in and unselect the browser.

How can I install a jre on client machines with no Internet Access

Hi
I have a lot of client machines located throughout the country which are connected to a central network (Oracle) application server. The client machines do not have internet access. The application now uses an applet which is accessible from the network. I would like to use the <jsp:plugin> tag to automatically download and install a jre on the client browsers that don't have a jre installed, when they access the jsp page. Unfortunately, even using iepluginurl="http://server-address/jinstall-1_4_2-windows-i586.cab, the client machines still need to access the internet to install the JRE as the cab file needs to access files at the Sun site.
Is there any online jre installer, that can be used on a network where the client machines do not have internet access? Or do I need to install the JRE manually on each machine? The browsers are all Microsoft Internet Explorer.
Thanks
David

Thanks for your reply ChuckBing.
Unfortunately I had already copied the instructions I found in the Sun documentaion to the letter and it still needed access to the internet. In the end I solved the problem by pointing the iepluginurl to a non existent file and putting a URL, pointing to an offline JRE executable on the server, as the message that appears when the applet cannot be loaded. The clients then have the choice of downloading the JRE or installing it online by clicking on the URL.
Thanks anyway.
David

JRE version with Forms 10.1.2.3

I just finished installing the patch set 3 for Forms Services 10.1.2.0.2 to update to version 10.1.2.3. The purpose was for our users with Windows 7 IE 8 to be able to continue to use Forms.
I understand that this requires JRE 1.6.0_20. However, most machines still have 1.4.2_XX. I am able to use the updated version on my machine that is XP and IE 7 w/ the 1.4.2 JRE version. One of our users with IE 8 gets this message in the Java Console:
Java Plug-in 1.6.0_20
Using JRE version 1.4.2_12-b03 Java HotSpot(TM) Client VM
He has the new one installed but it forces use of the old one.
Does anyone have a suggestion in configuration with working around this issue for users that will use either version of JRE w/ this Forms update?
I think an answer would be to uninstall JRE 1.4.2 for users w/ IE 8 but we don't have admin control on our machines.
Not a critical issue but your advice/help is appreciated.

Phil,
When you upgraded, did you modify the formsweb.cfg to change the JRE requirement? If you didn't that would explain the message your user is getting:
Java Plug-in 1.6.0_20Using JRE version 1.4.2_12-b03 Java HotSpot(TM) Client VM>
As Chidu suggested, change the following lines in the Formsweb.cfg on the app server:
jpi_codebase=http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jre-6u22-windows-i586.exe?BundledLineItemUUID=D.uJ_hCujxcAAAErFOQkgqsv&OrderID=pYCJ_hCuGowAAAErCeQkgqsv&ProductID=mCuJ_hCyot8AAAEri7RGXQzG&FileName=/jre-6u22-windows-i586.exe
jpi_download_page=http://www.oracle.com/technetwork/java/javaee/downloads/index.html
jpi_classid=clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA
jpi_mimetype=application/x-java-applet;jpi-version=1.6.0Note: The above entries are JRE U pdate independent - meaning any version of Sun JRE 1.6 will work; it is not specific to update 21 (current update version).
Hope this helps,

JRE 5.0 and MS Runtime Error!

When I inadvertently let the 5.0 JRE install on my machine, I started getting a "Runtime Error!" in MS Windows Explorer.
The error was like this:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:\WINNT\explorer.exe
This application has requested the Runtime to terminate it in an unusual way.
Please contact the applications support team for more information.
Everytime I opened Windows Explorer, it would poppup this message and then crash the explorer. We tried multiple things to fix it, lots of ideas on the internet, but the only thing that would stop it is removing the JRE. Anyone else getting the problem?
FYI
I did not have google toolbar on my machine
my computer is well protected against virus' and adwares

Yes, I'm having this same issue after the exact same thing...let JRE 5.0 install, over-writing the old JRE. I'm going to uninstall the 5.0 and see if it helps.
I'm running XP on a work machine and I've done everything else...registry cleaning, virus scans (in safe mode), Ad-Aware scan, no Google toolbar. I've cleaned the mcapfbho.dll file, removed all unneeded add-ons in Office, Outlook 2003, and IE 5.5. I've disabled McAffee's spamkiller and Exchange sniffer. I've ran ISPFix.exe and BHO Captor....all this and still get the error.
Hopefully removing the JRE 5.0 works.

Discoverer Plus -- Cannot Load Java Applet after JRE upgrade to 6

Hi,
After our users upgrade Java Runtime Environment to version 6 Update 1, Discoverer Plus stops working, the applet is opened but does not load.
Uninstalling the update solves the problem.
I disabled the automatic upgrade of Sun JRE on a few machines, but we have over 100 users.
Did anyone else face the same issue and is there any patch for the Discoverer installation?
Thanks,
Vlad

Hi George
You can get the 10.1.2.2 patch (4960210) on MetaLink. Be warned though that this not a small patch. It is 1.6 GB in size and is a full upgrade of the 10.1.2.0.2 application server.
I had some interesting problems when I first starting patching up to 10.1.2.2. First of all, if you are using a Windows server, you need to make sure that there are no lowercase characters used in your computer name. I know this sounds crazy but 10.1.2.2 will fail on Windows if you have this. If you've already got lowercase names in your machine you can't simply change the machine name to upper case because your existing application server will stop working as it embeds the machine name into dozens of configuration and setup locations. None of the Microsoft applications care what you call the machine as they don't embed like this but Oracle does. You'll probably end up having to reinstall the application server. However, the good news is that this only affects Windows and only when you have lowercase characters in your machine name.
Secondly, also on Windows, make sure there are no spaces anywhere within any of the folder names from where you will be installing the patch. This is another cause of failure. Thus, don't put the patch on your Desktop as there are spaces in Documents and Settings!
Thirdly, and this can happen on all platforms, if you are using an Infrastructure database and it is at 10.1.0.4 or less you will need to upgrade that database to 10.1.0.5 before you start any of the application server upgrades. If you don't do this your upgrade will fail. The release notes for the patch clearly state this but because they are very large I missed this the first time round and - oops - failed upgrade.
By the way, it seems Oracle have also released a patch (5758865) , available on MetaLink, with the fix for IE7. This is a one-off patch and requires a password which means you will have to raise a service request and tell Oracle you are having trouble drilling in Viewer when using IE7. This patch is applicable whether you are using relational or OLAP modeling. It can only be installed on top of 10.1.2.2.
Best wishes
Michael
