Today, after so many years working in IT industries as enterprise architect, I decided to start my own project about enterprise integration framework. First, I want to make sure that I can setup a home network and invoke the web services within the my home network. First of all I tested the connection of my home network. I can ping from my MacBook Pro to my laptop which is named as Gary-Work. Secondly, I installed Apache Tomcat 7 and Apache Httpd. I configured https port at 8443. I will add steps on how to do this. Then, I started the Tomcat as windows service. It works fine on the host of Gary-Work. That means I can invoke the default page with https://gary-work:8443 and http://localhost:8080. All work fine. I thought everything is working fine. Then I tried from MacBook Pro. It did not work. After I googled the issue. I found one post mentioned that this could be a firewall issue. After I check my windows firewall configuration, I realized that is the problem. OK, I add a firewall rule with ports 8080 and 8443. Then I can invoke my Tomcat web page from the MacBook Pro.
