PersistenceManagerFactory not initialized while accessing wookie in tomcat

I am trying wookie inside tomcat. Whenever I try to run wookie through (http://localhost:8080/wookie) I get the following log.

org.apache.catalina.core.StandardWrapperValve invoke  
SEVERE: Servlet.service() for servlet jsp threw exception

I have followed the instructions at wookie docs (incubator.apache.org/wookie/downloading-and-installing-wookie.html)

and this is my build.properties file and uploading.com/files/6cb5582d/build.xml file

What could be the possible causes of above problem?

From serverfault vivek.m

• servletEngine.context.conf.dir=CATALINA_HOME/conf/Catalina/localhost
  

  DO NOT MISS Catalina/localhost after conf. otherwise above mentioned problems will occur. I still do not know why it wants Catalina/localhost path instead if just conf dir path!!
