[Building Sakai] Getting toolPlacement in sakia(BeanNotOfRequiredTypeException)

[Aaron Zeckoski]

This is normally caused by getting some jars mixed up in your
installation. Check that you only have one copy of the kernel jars in
shared and that you do not have another copy in your tool war or your
component directory.
Sometimes the easiest way to be sure is to simply delete your tomcat
and put a clean copy in place and then re-deploy sakai into that.
