MS java virtual machine

[odidio]

I looked into this a while back but put it on hold, the MS version (JVM) will be supported until Dec./07 I guess, but what is the best way to upgrade to Sun's JRE 5.0 ?

The removal tool for JVM is still available from MajorGeeks and others but I was reading about problems users had due to removal of the MS version. I also heard of problems with having both versions installed.

Officially MS Java' virtual machine' is supported til whenever, but the fact is its been abandoned for quite some time. It hasn't been updated in forever, and never will be again. Its probly not even that secure to use it anymore. I personally prefered it over Sun Java too, but its just not an option anymore.

You don't have to worry about 'upgrading' to Sun java, as the two are separate instances of java and will not conflict. At least they never have for me, I still have MS java on my system, nothing has used it even once in forever, but its still there, and has given me no problems.

How about getting it as a Firefox plugin (https://pfs.mozilla.org/plugins/) ?

Or do I realy need it at all ?

[xpgeek]

If you have Sun Java installed on the system, then no you won't need to install anything extra for Firefox.

One last one for you, I know that when I download a program it usually takes up a little more disc space than what they claim the size of the program is. With Firefox it was supposed to be 4.9 Mb but it's showing up in add/remove as 17.5 Mb. No plugins, extensions or extra skins.

Just curious.

If you updated Firefox and didn't remove any previous version, or there is a plugins folder that contains any addons that you have not installed, will register in Add/Remove Prograns along with the original size.

Firefox 1.5, cleanly installed, is 15.5 megs in add/remove programs for me.

But all programs do that. Notice when you install Firefox, the first thing you see is 'extracting files', downloaded installers are compressed, the .exe is kind of like a zip file.

OK, I've uninstalled and reinstalled the latest, it's now 15.59 Mbs.
That explains things xpgeek, I thought it was a regular .exe.

Thanks.

J2SE 5.0 Update 6 - 119 MB, does that sound about right ?

[Micron]

I updated after a format, was a big file.

[xpgeek]

Its like 30 or something, if I remember right, to download, but yea J2SE 5.0 Update 6 - 119 MB is exactly what I got in add/remove programs too.

You can download a tool Here (http://www.microsoft.com/downloads/details.aspx?FamilyID=4e38f4f9-ce7e-4271-8836-a7d7293a992f&DisplayLang=en) to find out if/what version of Microsoft VM is on your computer.

To remove VM manually simply do this:

To do this go to Start > Run and paste the following into the run box RunDll32 advpack.dll,LaunchINFSection java.inf,UnInstall
If you are running an older version of the JVM you may need to upgrade to version 3809 or 3810 (windows update) before the above command will work.

You will then be asked if you really want to remove the virtual machine and then reboot. At this point if a message is displayed to the effect of 'removing the jvm will prevent you being able to download files' this refers to files downloaded through java applets rather than regular file downloads. Although the VM has now been removed it has not removed all remnants of the VM's existence from your machine, if you wish you can remove the following without adverse effect.

Registry Keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Java VM
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\AdvancedOptions\JAVA_VM (Key used for VM entry in IE Advanced Options)

System Folders and Files
C:\WINDOWS\System32\jview.exe
C:\WINDOWS\System32\wjview.exe
C:\WINDOWS\inf\java.pnf
C:\WINDOWS\java
(C:\Windows represents the drive and path of your windows install, %windir%)

You can download Sun java as a manual download from Here (http://java.sun.com/javase/downloads/index.html) click on J2SE5.0->JRE 5.0 Update 7 includes the JVM technology->Accept->Windows Offline Installation, Multi-language 18.23MB. :wink:

Another easy way to tell if Java is installed and which vendor and version is this site.

I didn't bother taking off the MS version before installing Sun's and there doesn't seem to be any conflicts.
