Subject Re: Binary Dist. tomcat 4.01 Win32 can't find jdk on installation

It seems very likely that your environment variables exceed the maximum 
allowed bytes. I am not sure but I think it is 4 or 8 KB. Since changing 
the environment variables (such as path, classpath etc) requires a reboot 
for system variables, many software vendors do not properly uninstall 
software and after a while you have a lot of crap in your path variable. 
Clean it up manually (in Control Panel, System Icon, Advanced Tab, 
Environment Variables Button),  reboot your box and it is most likely that 
your JDK is recognised by TOMCAT.
