Run myBlock in Tomcat fail

[Rice Yeh]

Hi,
  I follow the insturction in http://cocoon.zones.apache.org/daisy/documentation/g1/1159.html to run the 2.2 version. The result is good in jetty. However, when i run the same block with tomcat, I always get the following error messages:

Jul 26, 2006 2:53:41 PM org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
Jul 26, 2006 2:53:41 PM org.apache.catalina.core.StandardContext start
SEVERE: Context [/cocoon] startup failed due to previous errors

Any clue?

Regards,
Rice
