Problems changing the SSL port number on Tomcat in Windows

I tried changing the SSL port number on my Tomcat server in my Windows Server 2008 machine and I kept getting the following error when going to the https version of my webapp:

Socket bind failed: [730048] Only one usage of each socket address (protocol/network address/port) is normally permitted.

To solve the problem I did the following:

1. Re-installed apache using the Windows service installer and specifying the JDK’s JRE as the JRE to use.
2. Set the keystoreFile attribute in the SSL connector tag in the server.xml file to a relative path. The path is based in Tomcat’s installation folder, so if you intalled it in c:\apache and specify ./mykey.bin in the  keystoreFile attribute, Tomcat will try to find the c:\apache\mykey.bin file.
