Localize Friends is a Java-Web-Chat, which uses Java on server side, but no Java on client side. All clients, PC and mobile phones, can use the chat with normal browser without any additional components or plugins.
The LoFi-Chat offers therefore the following advantages against other chat systems:
1. Java on server side has better performance than other technologies like script languages as PHP.
2. A Web-Chat, which does not need any additional client software, could be used from everywhere (also behind Firewalls) and with every communication device which has Browser/Internet.
