Tigase should start listening on port 8080 - you can check it using lsof command:
$ lsof -i -P COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME java 18387 tigase 141u IPv6 22185825 0t0 TCP *:8080 (LISTEN)
You can also check console log under logs/tigase-console.log, which should point you directly to the installer.
