MS JVM

[Peter]

We are using Windows XP Professional SP2. We would like
to know how to find out whether there is any JVM installed
on the machine ?

Besides, if there is not, which JVM should we use - MS JVM
or Sun JVM ?

Thanks

Hi Peter - You can test whether Java is working on your machine at the
following sites:

http://www.pocoso.de/pocoso052.html
http://www.clan.lib.ri.us/clan/javatest.html (This one may be down)
http://www.fitwise.com/testjava.asp (both 1.0 and 1.1 and what's installed)
http://coglab.wadsworth.com/support/browsercheck.html
http://www.ces.clemson.edu/webct/browser_detect.html

and you can test Javascript here:
http://www.dancespots.net/browsertest.htm


There is good information concerning all aspects of the Java situation here:
http://www.javatester.org/installing.html

Be aware, however, that after Dec 31, 2007, MS will apparently no longer be
distributing Java or providing any support for Java including security
fixes. See here: http://www.microsoft.com/mscorp/java/ so you might want
to start thinking about the future.

You can get the Sun Java J2SE RunTimes or SDK here:
http://java.sun.com/downloads/index.html (all versions - select using the
dropdown)

Sun also offers an automatic download and install of the 1.4 Java plug-in
here: http://java.sun.com/getjava/download.html



For the MS Java VM, you may need to install v.3805 or v.3809 prior to
upgrading to v. 3810 if you didn't previously have MS Java v. 3805 or 3809
installed.

If your OS is Win2000 SP2, SP3 but NOT SP4 then you can download and install
MS Java VM v. 3809 from here:
http://download.windowsupdate.com/m..._510A502BA8F9B6F19230BB2BCCE87D5474AC9DCD.exe
or here:
http://www.biologylab.awlonline.com...icrosoft.Q810030_W2K_SP4_5849/Q810030_W2K.exe

For Win2000 SP4, follow the directions here: Frequently Asked Questions
About the Microsoft VM and Windows 2000 Service Pack 4
http://support.microsoft.com/?id=820101 "Because the Microsoft VM files are
not protected by the Windows File Protection (WFP) feature in Windows 2000
SP4, redistributable versions of the Microsoft VM can be installed on a
Windows 2000 SP4-based computer with or without the Microsoft VM."


For all other OS's:

Download and install the MS Java VM v. 3809 from one of the links here:
http://ftp.idilis.ro/windows/sp/jvm98/msjavwu.exe, or here:
http://secinfo.huji.ac.il/patches/Win-xp/msjavwu.exe or v. 3805 from
here:
http://www.sijet.com/msjavx86.exe


Then upgrade to v. 3810:

For all OS's except Win2kSP4 obtain v. 3810 here:
http://fileforum.betanews.com/detail.php3?fid=1050022631 ,or here:
http://download.windowsupdate.com/m...l/MSJavWU_8073687b82d41db93f4c2a04af2b34d.exe

For Win2k - SP2, SP3 - you can also obtain v. 3810 from Microsoft here:
http://download.microsoft.com/downl...-9b18-423356321682/Q816093_W2K_SP4_X86_EN.exe

For Win2kSP4, to get 3810 from Microsoft you now have to get Q816093 from
Windows Update Catalog - use the procedure given in the Q820101 link given
above for Windows 98 and Windows 98 Second Edition (Yes, Win98x/SE - it's
not a mistake). You can find directions for using the Windows Update
Catalog functions here:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;323166.



Both Java VM's can co-exist on your machine quite nicely. Just select which
one you want to use in Tools|Internet Options|Advanced and restart all IE
browsers. Here, courtesy of Mitch Gallant, MVP Security, is a tiny utility
which allows you to toggle and view status of your current Java VM vendor
associated with IE:
http://www.jensign.com/JavaScience/SelectIEJVM/index.html

A note from Mitch Gallant:

"One note about the JVM Selector utility: If/when you install a new
version of Sun J2SE, you need to manually select to have Sun JVM as default
JVM for IE (in install), or after install via the JavaPlugin control panel.
This generates the necessary win32 registry entries, which must be present
for the utility to know about JavaPlugin. After that, the utility should
work properly."

or Sun JVM ?

The MS JVM is extremely out of date by this time. Use the Sun JVM,
available here: http://java.sun.com/getjava

 

[R. McCarty]

Simple answer - Sun created/maintains Java. Microsoft is now
prohibited from re-working/distributing it's own Java. It's like
getting a modified version of XP from Apple - Stay with the
source.

Microsoft are not permitted under court order to make their VM
available, so it is not in XP original or either available Service Pack
(it was in SP1 and had to be removed to produce SP1a). You can still
find a 3805 or 3809 build on the net and can then update that to 3810 -
the final build.

There are some sites that may require still the extra facilities of the
MS one, I would install Sun and use that until such time (possibly
never) that you run into one of these. You can have both installed and
use Sun's applet to switch - or I have that set to use MS in IE6, Sun in
Firefox
