I had the same problem. can you Read this
This is only the effect of a previous error. Cocoon has the following web.xml configuration: <load-on-startup>1</load-on-startup> This means that Tomcat will load Cocoon at Tomcat start (as opposed to first access of CocoonServlet). If CocoonServlet throws an exception during init, Tomcat will consider the servlet as uninitialized and will try to re-init on first access. Ie one "half-init + break" + another "half-init + break", which gives you troubles with anything loaded statically in the JVM during the part of the init that actually works (eg configuring the Cron block and Quartz scheduler). You should search for the previous error in the Tomcat and/or Cocoon logs and try to get help on the Cocoon user's list (don't focus on the "cannot create a quartz scheduler", during testing it might also be easier to set load-on-startup=0 in Cocoon's web.xml). You can use Tomcat's Manager application [1] to check the init-status and if Tomcat considers the servlet to be loaded.
