UNinstalling the Microsoft Java VM? (IE6SP1)

[JohnGray]

Does anyone know:

a) IF the Microsoft JAVA virtual Machine can be uninstalled from Internet Explorer 6?

[img]/forums/images/smilies/cool.gif[/img] WHETHER it's necessary to uninstall it to add, say, the Sun Java VM?

Thanks very much!

John--I'm sure you have it taken care of by now. I ran into this while I was searching for some links on a back IE thread and I was trying to answer a JVM/MVM question.

Essentially, you can uninstall the MVM by running "regsvr32 /u msjava.dll"

Uninstalling Microsoft VM

Whether to install Sun Java largely would depend on why you want it--it certainly can't have a downside for you. Some links on this thread may help you context it. I needed to work with something that demanded it, so I have it. Microsoft is as you probably know pulling all support and updates on January 1, 2004:

Hi, John ~

<hr>WHETHER it's necessary to uninstall it to add, say, the Sun Java VM?<hr>

No, it is not. As a result of using Firebird browser, I have them both installed w/o incident over the last 2 years. I do find the Sun version annoying, though, as it always starts a process that it doesn't want to let go and rears itself in the systray.

[JohnGray]

Thanks, both - I was despairing of an answer from someone who knew what they were doing! I certainly don't!!

LATER...

I now understand the ACTUAL question should have been:

<font color=blue>"Is it possible for the SUN Java Runtime Environment AND the IBM equivalent to co-exist on a Windows XP Pro box, having first removed the Microsoft Java Virtual Machine?"</font color=blue>

I suspect that the number of people/organisations actually knowing the answer to this is approximately zero. Or less... <img src=/S/sad.gif border=0 alt=sad width=15 height=15>

Uh...did you misread Bruce's post? <img src=/S/smile.gif border=0 alt=smile width=15 height=15> Bruce didn't say to uninstall VM; he said it wasn't necessary to uninstall it to install Sun's.

[SMBP]

Absolutely I misread it sorry.

Hi, SMBP ~

<hr>or many, like Bruce, if you never heard of it it won't matter if and only if you don't need it.<hr>

<img src=/S/confused.gif border=0 alt=confused width=15 height=20> Huh? Clearly I have heard of it as I do in fact use both versions. How were my short sentences misread? <img src=/S/confused.gif border=0 alt=confused width=15 height=20> <img src=/S/laugh.gif border=0 alt=laugh width=15 height=15>

[JohnGray]

Hmm. After all that, I suppose my question should <big>really</big> have been:

<font color=blue>Is it possible for
the Sun, the IBM, and the Microsoft,
Java
Virtual Machines/Run Time Environments
to coexist without interaction on XP Pro?</font color=blue>

But it may be quicker to scub the whole idea and go for GWBASIC... <img src=/S/hairout.gif border=0 alt=hairout width=31 height=23>

If you are doing day to day home and office computing, you may run fine without any type VM on your system sure. But if you are running something that needs to interpret compiled java code or byte code for a computer's processor so that it can interpret instructions then you need a virtual machine. The idea was to allow application programs to be built that run on any platform without having to be rewritten or compiled for each separate platform. A JVM makes this possible because it is aware of the specific instruction lengths and peculiarities of the platform. If someone built an application with visual J+++ or the Microsoft SDK for JAVA, they might be looking around for a virtual machine. For many individuals who want to play old games on certain PC's then a virtual machine can come in pretty handy.

You are quite correct. Look up an inch above your picture (Post 7 hours earlier to Phil who was kind enough to point out my oversight) and you'll see I said they were, but the other sentence was meant to read that if some people never heard of JAVA or a virtual machine, they could cruise through life without either of them and still do what they wanted on a computer. Microsoft won't be supporting their VM (one of the ones you have come new years according to all their JAVA sites-- whether that means it will cause any problems if you don't uninstall it by then I'm sure will be discussed all over the place way ahead of that date. Perhaps it won't matter if you have one of Sun's as well.

Sorry for any inconvenience--will reword the post for posterity. Enjoy the Java white papers and your two virtual machines. I wonder which one does the java byte processing because Sun and Microsoft have been pretty contentious over their machines with millions of dollars of Baltimore District Court and 4th Circuit appellate briefs. At least the attorneys for these respective companies are eating well and drinking a lot of Starbucks in Seattle and California thanks to JAVA.

I misread Bruce--sorry for the confusion. They can as Bruce said with no problem--I have them both but only because I was prompted by something I wanted to use to add the Sun, and truth is I added the Microsoft because at the time they hyped it as such an essential download and then (no longer) I was downloading nearly everything Microsoft offered for my OS/browser/and Office as updates.

1) I do wonder if you have them both and some JAVA byte processing is needed, which one of them does the work.

2) Since even if you don't program (and I don't and because of it lose the ability to appreciate JAVA as much as I would if I did) you see everywhere that xml language, xml processing, xml security is going to be more and more widely used, and Microsoft has said in a sense "they're betting the farm on xml "and we're going to hear so much of it as Office 2003 launches with some degree of XML in the different versions--they're debating whether to offer all of it to all versions now according to the newsletters-- I wonder if these java downloads will become more and more important for the everyday user to have in the future just say to run Office and view day to day web pages as the web turns more to xml.

What is JAVA?

A lot of people may understand JAVA and all its spinoffs very well--I still have to grapple with it every time I see the term "java applets" or javascript or java mentioned period.

I appreciate your bringing this up John--it just makes me try harder to understand how much of a part of what I have to do JAVA/XML is going to be with the upsurge of xml applications--and how much it has been.

Hi, John ~

I didn't know there was an IBM version, but my curiosity is piqued. Send me a link and I might try to guinea pig it. <img src=/S/mice.gif border=0 alt=mice width=50 height=25>

[JohnGray]

We're apparently going to standardise on the IBM version, following the withdrawal of support by Microsoft, but we still need the Sun JRE for one wretched application.

Tomorrow I will try to track down the person who's working on it to see where he has obtained it from. Putting "IBM Java Download" into Google might not be sufficient, since it keeps saying stuff about WebSphere...

[SMBP]

Took a quick look. So many years, so many versions, so many types of applications. If you know what you want have at it. Use different Googles, use Teoma or some other SE's and drill IBM's sites and you'll probably come up with what ever version of IBM jvm you're after.
