which will create a /var/tomcat4 directory, a /etc/init.d/tomcat4 control script and a configuration file /etc/tomcat4/conf/tomcat4.conf.
Unfortunately Tomcat does not set the permissions correctly in the /var/tomcat4 directory. Please change the permissions so that a ls al looks like this:
drwxr-xr-x 10 root root 4096 Feb 4 16:31 .
drwxr-xr-x 17 root root 4096 Feb 5 16:00 ..
drwxr-xr-x 2 root tomcat4 4096 Feb 4 16:31 bin
drwxr-xr-x 4 root tomcat4 4096 Feb 4 16:31 common
drwxr-xr-x 2 root tomcat4 4096 Feb 5 17:36 conf
drwxr-xr-x 2 root tomcat4 4096 Feb 4 16:31 lib
drwxr-xr-x 2 tomcat4 tomcat4 4096 Feb 7 11:40 logs
drwxr-xr-x 4 root tomcat4 4096 Feb 4 16:31 server
drwxr-xr-x 8 tomcat4 tomcat4 4096 Feb 5 17:19 webapps
drwxr-xr-x 4 tomcat4 tomcat4 4096 Feb 5 17:37 work
If the permissions are set differently the automatic extraction of the cocoon.war file will most likely fail.
