Hello,
I have an XP pro system with SP1 (MSJVM was there).
I was upgrading to SUN JVM.
I uninstalled the MSJVM using the "unmsjvm.exe" tool that MS had released for a while.
I installed the Sun JVM  j2re-1.4.2_05.
It all looks fine in Java console.
However, My applets simply don't load after these changes.
I never had problems with the sun jvm on other XP SP1a systems so Im thinking it had to do with removing the MS jvm.
IE is enabled in the java console,
Sun Java is enabled in IE|tools|ie options|advanced
any ideas?

try running this tool:
http://www.mvps.org/sramesh2k/IEFIX.htm

if it cannot solve the problem,,,,,, just ry reinsalling MSJAVA >> http://hp.vector.co.jp/authors/VA012735/vm_en.html
to check if it can solve the issue or not ??
and dont worry abt having bot Javas on the machine on the same machine,,,,, it doesn't harm ur system :)

You could also use the Sun Java Virtual Machine (Download J2SE JRE) from this page http://java.sun.com/j2se/1.4.2/download.html

Good luck with it

I had to re-install the msjvm per the suggestion.
He pointed me at a site with tool:  msfavx86.exe
  I had to search web and find a faster site but once I knew that there was such a tool (to reinstall the msjvm) and what its name was, it worked quickly.

conclusion:  dont uninstall the msjvm that came with pre-SP1a windows XP.
   It doesnt hurt anything.  Sun Jvm can be installed with it left on the machine.
   If you do uninstall it, you may not be able to get the sun jvm to work.
   Im betting that the sun jvm is doing different things on pre-SP1A XP OSs
     and interacts with the browser differently.
thanks sheharyaarSaahil for the insight.
