Dear guy,
to change Apache port you have to edit server.xml and change connector port=xxxx
In our case we have a server.xml of Tomcat 7 in the following directory
C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf
and the line with connector port string:
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
