If you install SSL-Explorer onto an Ubuntu 8 (Hardy Heron) install, there will be an issue after a reboot where the service will start but you will not be able to log on to SSL-Explorer.

 
This is fixed by doing the following:

cd /opt/sslexplorer/conf
sudo gedit wrapper.conf

Find the line starting wrapper.java.additional.1= and add a new line underneath, make this new line read:
wrapper.java.additional.2=-Dfile.encoding=UTF-8

Save the file. Now next time Ubuntu restarts, you will be able to log in ok.
