In response to:

<ul id="quote">Well, I need both version of VM. Sun's for javascript enabled sites
and Microsoft's for some sites (like : www.money.net) that run Micosoft's java applets. </ul>

The JVM has nothing to do with JavaScript. Java applets and JavaScript are completely unrelated. Most websites use JavaScript to some degree and this simply requires an appropriate engine in the browser; just about all modern browsers can handle JavaScript, although they differ slightly in how much they adhere to the DOM and W3C standards.

Java applets, on the other hand, require a JVM to run. As already stated, most applets will work with either JVM, although I have personally found the Sun JVM to be more reliable.

MS JAVA VM Removal / REINSTALL
The W2K server SP2 was IE 5.5 SP2 was upgraded to Internet Explorer 6.0 SP1
Now there where some problem's, !!! not suprised !! Microsoft Java didn't work anymore, and sun java was not a solution because the intranet was build on M$ Java. So The server was upgraded to SP4 ?. Did not bring the solution.

I am running Windows 2000 Server SP 4 with citrix and did the following:

- deinstalled all sun java's,
You will have to check if java is installed, you can do this : START -> RUN -> CMD (enter) -> jview , if you get an aswer it is installed. The following commando wil do an uninstall. The deinstall did not work at first on my server because the java.inf file was missing. you can steal this from an other machine and put it in %systemroot%inf .

- RunDll32 advpack.dll,LaunchINFSection java.inf,UnInstall (manual removal of ms java vm)

After you did the deinstall you need to do a reboot, because some files are locked.

remove the %systemroot%java folder
java.pnf from the %systemroot%inf folder
jview.exe and wjview.exe from the %systemroot%system32 folder
The HKEY_LOCAL_MACHINESOFTWAREMicrosoftJava VM registry subkey
The HKEY_LOCAL_MACHINESOFTWAREMicrosoftInternet ExplorerAdvancedOptionsJAVA_VM registry subkey (to remove the Microsoft Internet Explorer (IE) options)

Microsoft Java is now deinstalled.

Because I Run SP4 on my W2K machine The java installation package could not install telling me that I needed to downgrade or whatever? So I needed to do a force install with no check.

Go to START --> RUN , and run the following command (probebly you have a different Directory for c:downloads and you'll have to include the quotes.)

"C:downloadsmsjavx86.exe" "/c:javatrig.exe /L /exe_install /nowincheck"
I think you can do this also on other machines.

After this you need to upgrade to MS JAVA VM 3810

Well, I need both version of VM. Sun's for javascript enabled sites
and Microsoft's for some sites (like : www.money.net) that run Micosoft's java applets.
Usually, when installing Sun's J2RE the installation -uninstalls- Microsoft's
VM, which has to be re-installed and wich is hard to find as Microsoft doesn't support the program anymore.

Any solutions ?

Be aware that in order to install Sun Java you may have to switch off the XP firewall!
