Sean Owen,
   Thanks for your reply, the hostname I use is one of my server computer,
it is too long, so I use hostname in the email.
I just have "mahout-taste-webapp-0.2-SNAPSHOT.war" in the
"$MACHOUT_HOME/taste-web/target" folder. Do I need install the tomcat at
first?
I follow each step of the "lucene.apache.org/mahout/taste.html#demo"
