I little server administration script would do.  Something with the sed 
command:

echo tomcat*/server.xm | sed s/80/8081/g

If you wish to give a different port for each, use a for loop.  This is 
not correct but the right idea:

#!/bin/bash
port=8080
for var in `find ./ -name server.xml`
do
echo $var | sed s/80/$port/g
port=$((port + 1))
done

This is assuming the script already has port 80 as the default.  Just 
find what it is exactly you need to search for to alter it with 'sed'.
