I am using Tomcat 4.1.12 on a Win2000 server box. It has been running well
until 2 weeks ago. The log files starting reporting the following (I
removed lines where ".... edited ...." appears but I can easily send the
full text):

Hi, it looks like something has been rearranged on your server and
tomcat can't find the class scroll. Maybe no help but I've had similar
issues where I had just moved a file.

Maybe make sure scroll is there ... go to the INVOKER directory
org.apache.catalina.INVOKER.scroll

There is no Invoker directory or .jar. I found Catalina.jar, but there is
no package or class for Invoker or Scroll - I looked on my test copy of
Tomcat 4.1.12 which does not have the problem. This is frustrating - looks
like there's a reinstall in my future.
Thanks
Tom
