i've just inherited a server ubuntu 10.04 running already tomcat on port 80.so apache 2 /etc/apache2/ports.conf has Listen 8858.
i pointed my subdomain let's say admin.domain.com to the ip of that box so xx.xx.xx.xx:8858 and admin.domain.com:8858 both sends me to the root file "it works" 
so i did create under /var/www/vhots/admin.domain.com/htdocs and /var/www/vhots/admin.domain.com/log my first config looks is below and that basically after reloading and restarting the apache2 gives me this error
VirtualHost *:8858 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results httpd (pid 7466?) not running
###/etc/apache2/apache2.cong NameVirtualHost * #NameVirtualHost *:8858 <VirtualHost *> ServerAdmin webmaster@localhost DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

NameVirtualHost *:8858 has no VirtualHosts httpd (pid 27536?) not running [warn] NameVirtualHost *:8858 has no VirtualHosts [fail]
How can i get it up? Thanks for reading this
