Try to do what Mark suggested :) The shared class loader has been
"replaced by/merged with" the common loader. The common loader holds all
classes and libs, that are common (shared) across all webapps.
Copy everything (watch out for jars with same/similar names) that you
found in your extracted shared folder into the lib folder. (If there
really is a folder called Classes, that contains the class structures,
copy the files/folders from inside Classes into the top level lib/ folder.)
It might help, if you post the elements of your shared folder, so that
others can have a better guess on where to copy those.
If you want to get fancy, you can edit conf/catalina.properties and edit
the property "comon.loader" to include your shared folder. Be sure to
both entries for the classes and the jar files.
You might want to have a look at RUNNING.txt. There is a description on
how to setup tomcat for multiple installations. Those setups are - in my
opinion - easier to play with, as you are not messing with the original
installation but a minimal shallow copy.
