Tomcat – Pentaho : ‘docbase’ did not find a matching property

I’ve been using Pentaho “biserver-ce-3.8.0-stable” run on Tomcat 7. But everytime I start Tomcat, show some message like this:

May 11, 2011 3:02:13 PM org.apache.catalina.startup.SetContextPropertiesRule begin
WARNING: [SetContextPropertiesRule]{Context} Setting property ‘docbase’ to ‘webapps/pentaho/’ did not find a matching property.

So to get rid of this warning message, I delete

docbase=”webapps/pentaho/”

from

<Context path=”/pentaho” docbase=”webapps/pentaho/”>

in “webapps\pentaho\META-INF\context.xml”. Now, I see Tomcat run smoothly (“INFO: Deploying web application directory pentaho”). ^_^
