Subject RE: C2.0.2: ClassCastException
Date Fri, 29 Mar 2002 01:44:18 GMT
Check your cocoon.roles and cocoon.xconf files. Cocoon 2.0.2 uses
XPathProcessor from the Excalibur instead of old Cocoon's
XPathProcessor. It seems that somehow you are instantiating old
processor instead of new, which is seen from the exception:

> java.lang.ClassCastException:
> org.apache.cocoon.components.xpath.XPathProcessorImpl

You have got org.apache.cocoon.components.xpath.XPathProcessorImpl
instead of org.apache.avalon.excalibur.xml.xpath.XPathProcessorImpl.

Regards,
Vadim
