I want to encrypt the http traffic on a tomcat instance via ssl. Therefore I followed the most simplistic approach described on various webpages. But anyway it simply does not work. Here is what I did:

1. "keytool -genkey -alias tomcat -keyalg RSA" and I enterd "changeit" as the password (since this is the defaut chosen by tomcat)

2. Altering $CATALINA_HOME/conf/servers.xml by uncommenting the following line

   Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS"/

3. Restarting tomcat

Entering

https://localhost:8443

does not work. However, I can still access the page via normal http like

http://localhost:8080

The logfile does not contain any suspicious information.

What is going wrong here?
