Tomcat 4.1.30 on Win2k: New Java SDK/JDK breaks Tomcat running as a Service?
Hi, all.
I've got a collection of very old versions of Windows, Tomcat, and Java. My
working configuration is Windows 2000 Professional, Tomcat 4.1.30, and Java
SDK 1.3.1_09.
When I install a newer version of Java and remove 1.3.1, the three instances
of Tomcat that I use will no longer run as a service. When Windows starts
up, or when I attempt to start the services manually, I get the following
error messages in the NT event viewer:
"Could not load the Java Virtual Machine. "
"The LoadLibrary function failed for the following reason: The specified
module could not be found."
Combing over the documentation, this seems to be caused by an incorrect
configuration of my environment variables. So, I checked (and
double-checked) that they're correct. When Tomcat works, I have a JAVA_HOME
of c:\jdk1.3.1_09 and a PATH entry of c:\jdk1.3.1_09\bin. When it doesn't
work, the JAVA_HOME and PATH entries point to where I've installed whatever
new version of Java I'm trying (1.4x, 5.x, or 6.x), which is just off of the
root directory of c.
Now, when I attempt to start Tomcat using the startup.bat, it works just
fine.
So, here's my two-part question: Is there something else that I need to do
to my environment variables in order to get this to work? Furthermore, is
there a setting in any of the xml properties documents that I can adjust to
"force" Tomcat to look for a jdk/j2sdk in the location of my choosing?
I do have plans to update all of this stuff to much newer versions of both
the OS and the Java components, but right now, I can only update Java; I
have to stick with the current version of Tomcat.
Thank you for the assistance!

You'll need to configure the service to use the new JVM.
Also, you may hit this issue:

Hi, all.
I found what I was looking for. The values that are set when the services
are installed are located in the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<Service
Name>\Parameters
I changed the path to the new jvm.dll for v1.6_05, and my services came
right up.
Thanks for all of the speedy assistance!
Regards,
Eric B

Hi Eric. What do you see when you right-click My Computer, choose Properties/Advanced tab/Environment Variables button. It used to be part of the java install to configure JAVA_HOME from here.

Haw haw haw. I have finally graduated, Chuck (but only to 5.5) ;)
Sorry, Eric, but I was never running Tomcat on Windows. A quick web
search seems to indicate that Tomcat 3.x used registry keys under
HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation for settings like
this. I also found this:
http://www.pauaware.co.nz/tomcatntservice.htm
You should check these registry locations before modifying your service
definitions.
Good luck,

I don't know with that version of Tomcat, since I've never used one that
old. The newer ones come with the previously mentioned utility that
will let you check and modify.
Perhaps Chris S could help? He's still using 4.1, but possibly not on
Windows.

Hi, Chuck.
Thanks; that sounds like exactly the solution I should have thought of,
myself. :-)
In terms of the reinstall, is there a way to see what settings were applied
when the services were installed, originally? Not all of the Tomcats on the
server "belong" to me, some of them came with a third party utility whose
documentation has long since vanished into the ether.
Thanks for the help!

You need to delete and recreate the services. The existing ones are
likely pointing to the old JVM location, rather than the new one. More
recent versions of Tomcat come with a utility to let you update the
service settings (tomcat{5|6}w.exe), but I don't know if that's
available with 4.1.

Services do not use environment variables.
