Install Tomcat 7 / 8

Is configuring Tomcat7 for the old Tomcat5.5 classloader dir structure still required for Sakai2.9 installs, or is this just to get Sakai2.7 working with Tomcat7?

It's still required at the moment for 2.9. We discussed on some of the lists changing the deployment scripts either dumping it into the same lib, or everything into a different lib (like /sakai/lib, which would still require modification). Neither of these are done and ready for 2.10 though.

What's the difference between step 2 and step 3, seems just the same.

And Step 9-iii is not needed. Sakai doesn't use server.loader
