I tried several things now:
In deploy\jbossws.sar\jbossws.beans\META-INF\jboss-benas.xml I set the webServiceHost (i don't want the customer to see the IP) and the webServiceSecurePort.
In the server.xml i configured the port:
| <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" |
| | maxThreads="150" scheme="https" secure="true" |
| | clientAuth="false" sslProtocol="TLS" /> |
At last i added the security-constraint like Jim suggested.
The only change is that instead of the IP i get the URL now, but still as http and not https.
Apart from that i found this Bug Report: https://issues.jboss.org/browse/JBPAPP-4648
Within this bug report I found an article about setting up https as well: http://community.jboss.org/wiki/JBossWS-SecureTransport
But this didn't lead me anywhere as well.
