Shamrock's idea is correct and good. The only difference is, that if you want an absolute list of ports of configured ports (not only those that are currently up and running), you will not get it by checking which processes are there, since it could be, that one of them is down for maintenance or similar.
For the problem of the format the server.xml could be in due to manual editing, I would try to run following via ssh from one box that has hopefully access to all others so you don't have to log in into each of them. For stuff like this I usually do something like the following (of course depending they are in a similar directory - else you have to think about how to find those server.xml in different locations):

Code:
$> cat server.list
server_1
server_2
server_3
$> while read S; do ssh -n -o "ConnectTimeout=3" -o "BatchMode yes" $S "cat ~tomcat/conf/server.xml" | sed -n 's/.*Connector port="\([^"]*\)" .*/\1/p'

On a box where 3 instances of Tomcat are running, I get something like:
Code:
8080
8443
8444
8445
8446
8447
8009

Which are up and running you could get the other way with ps and lsof.

ssh-http-proxy-connect

ssh-http-proxy-connect(1)					   User Commands					 ssh-http-proxy-connect(1)

NAME

       ssh-http-proxy-connect - Secure Shell proxy for HTTP

SYNOPSIS

       /usr/lib/ssh/ssh-http-proxy-connect [-h http_proxy_host]
	    [-p http_proxy_port] connect_host connect_port

DESCRIPTION

       A  proxy command for ssh(1) that uses HTTP CONNECT. Typical use is where connections external to a network are only allowed via a proxy web
       server.

OPTIONS

       The following options are supported:

       -h http_proxy_host    Specifies the proxy web server through which to connect. Overrides the HTTPPROXY and http_proxy environment variables
			     if they are set.

       -p http_proxy_port    Specifies the port on which the proxy web server runs. If not specified, port 80 is assumed. Overrides the HTTPPROXY-
			     PORT and http_proxy environment variables if they are set.

OPERANDS

       The following operands are supported:

       http_proxy_host	  The host name or IP address (IPv4 or IPv6) of the proxy.

       http_proxy_port	  The numeric port number to connect to on http_proxy_host.

       connect_host	  The name of the remote host to which the proxy web server is to connect you.

       connect_port	  The numeric port number of the proxy web server to connect you to on http_proxy_host.

EXAMPLES

       The recommended way to use a proxy connection command is to configure the ProxyCommand in ssh_config(4) (see  Example  1  and  Example  2).
       Example 3 shows how the proxy command can be specified on the command line when running ssh(1).

       Example 1 Setting the proxy from the environment

       The following example uses ssh-http-proxy-connect in ssh_config(4) when the proxy is set from the environment:

	 Host playtime.foo.com
	     ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect 
		 playtime.foo.com 22

       Example 2 Overriding proxy environment variables

       The following example uses ssh-http-proxy-connect in ssh_config(4) to override (or if not set) proxy environment variables:

	 Host playtime.foo.com
	     ProxyCommand /usr/lib/ssh/ssh-http-proxy-connect -h webcache 
		 -p 8080 playtime.foo.com 22

       Example 3 Using the command line

       The following example uses ssh-http-proxy-connect from the ssh(1) command line:

	 example$ ssh -o'ProxyCommand="/usr/lib/ssh/ssh-http-proxy-connect 
	     -h webcache -p 8080 playtime.foo.com 22"' playtime.foo.com

ENVIRONMENT VARIABLES

       HTTPPROXY	Takes the http_proxy_host operand to specify the default proxy host. Overrides http_proxy if both are set.

       HTTPPROXYPORT	Takes the http_proxy_port operand to specify the default proxy port. Ignored if HTTPPROXY is not set.

       http_proxy	URL format for specifying proxy host and port.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       1     An error occurred.
