[Building Sakai] Rwiki ClassCastException on Tomcat startup

[Earle Nietzel]

I saw this in your log:

Caused by: java.lang.ClassCastException:
org.apache.xml.dtm.ref.DTMManagerDefault cannot be cast to
org.apache.xml.dtm.DTMManager

I think you have a classpath issue with xalan.

Check your jdk lib and lib/ext dirs for jars that might be getting on the
classpath, I would also make sure you are using a clean tomcat.

I found this while googling:
