Ho to setup GlassFish and phpMyAdmin on IIS 7

Question

I have successfully configured IIS 7 in order to display phpMyAdmin correctly on top, so that when I run http://mydomain/phpmyadmin it works. I also have GlassFish running on the same Windows Server 2008 on port 8080 for http and 8181 for https (using temporarily the auto-generated glassfish self certificate). In order to forward the requests to these ports automatically to GlassFish, I have done the following in IIS:

1. Create server farm
2. Given the name GlassFish
3. Server address: localhost
4. Clicked on Advanced settings. Expanded applicationRequestRouting node. Edited the available ports and clicked Finish
5. Clicked Yes to the request of creating the URL rewrite rule

Well, after these steps, I have the following problems:

1. all requests are forwarded to glassfish ports, and I cannot run phpMyAdmin anymore
2. the https sites don't work either, probably because IIS is not aware of GlassFish certificate
