Java Virtual Machine Launcher - ERROR

[Rob]

I am getting a warning message during initialization of
Windows XP Pro. "Java Virtual Machine Launcher could not
find main class. Program will exit."

Everything works fine for a while then problems start
with Windows on the desktop do not go away when minimized
or exited.

The system eventually stops responding. I have to reboot
to clean up the mess.

Could use some suggestions on how to fix this.

I suggest that you get Sun's Java Virtual Machine (JVM) and install it :

Hi Rob - You might want to re-install the Java VM(s).

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
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 previous have MS Java v. 3805 or 3809
installed.

If your OS is Win2000 SP2, SP3 but NOT SP4 then you can download and install
the 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, you'll need to re-install v.3805, from here:
http://www.download.support.safetec.net/msjavx86/msjavx86.exe
http://www.mvps.org/inetexplorer/msjavx86.exe


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


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 entry for Windows 2000 SP4 (this seems to
be the only Win2k option that has it) and then find 816093 in the list. You
can find directions for using the Windows Update Catalog functions here:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;323166. (I am
informed by Torgeir Bakken, MVP, that if you rename the downloaded file from
here: http://fileforum.betanews.com/detail.php3?fid=1050022631 to
msjavwu.exe it will then also work for SP4.)

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 Michel 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."

i am having the same problem let me know if you find out
anything

I am getting a warning message during initialization of
Windows XP Pro. "Java Virtual Machine Launcher could not
find main class. Program will exit."

or exited.

You have some sort of malware on the machine that in part starts by
running a Java program; it appears that that section has been removed
and has left an attempt to load it at boot. Start - Run - MSconfig.exe
and on the Startup page look for a line containing WJView or jview in
the Command Column. Uncheck it; Exit - do not bother to reboot, but
next time you do there will be a message about 'System Configuration'.
Check the 'Do not show again' box and exit

Then it looks as if you may have other parasites around still, that may
have climbed aboard at the same time. Visit
http://www.aumha.org/a/parasite.htm
read up, and use the tools suggested and linked in the Quickfix section.
Always make sure you have updated data for such programs before using
them
