I have the following error when connecting from tomcat, appears to me:

Err no se puedo cargar el driver en DefinitionConnectionPortal -->
DefinitionConnectionPortal Cannot create PoolableConnectionFactory
org.apache.commons.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory, cause:
Connection refused. Check that the hostname and port is correct, and that
the postmaster is running with the -i flag, which enables TCP/IP
networking.

The error message is pretty clear:

This message is perhaps outdated as the more recommended method of
enabling tcp/ip connections is by enabling tcpip_socket in
postgresql.conf.

This is unrelated to your immediate problem, but if you are using a 7.4
server you should also be using a 7.4 jdbc driver.

Why are you using a 7.1 driver with a 7.4 database ?

that withstanding do you have tcpip=true in the postgresql.conf or the
-i flag in the startup script ?
