How to change IP address on Oracle 10g xe

[Nenad Bulatovic]

Hi everyone,
a month ago I installed Oracle XE (following some book about SOA Suite 11g), and finally almost completed project, but at the end when I try to implement ADF Mobile solution as well, I got an error which is caused by Oracle XE listening on localhost, while mobile app tries to access it thought my PC external IP address. How should I change or add Oracle XE listener addresses, so that it listens on external IP as well?. I guess there must be some config file, where I can add binding address? I am using windows 7.
