apache > cocoon

Cocoon still won't start, this time I get javax.xml.transform.TransformerConfigurationException: Namespace not supported by SAXParser in the Cocoon log file.

This is a classloader issue with Tomcat and some other servlet engines. Basically it means that the Xerces library included with Cocoon is not being found. The solution is to place the Xerces library first in the classpath.
