Live Chat Engine - java chat open source engine
Live Chat Engine
Open source system for live chats with visitors (customers) in any site. Contains server-side (chats storing, users and billing management), operators cabinet for chatting and chat form for site's visitors.
Two work modes
Software as a Service (SaaS mode)
In SaaS mode clients create accounts for themselves and pay monthly bills. This mode is ready for production usage and enabled by default.
Example of implementation: cheapchat.me
Other popular examples: olark, livezilla, boldchat and others
Tool for Other System (Tool mode)
In Tool Mode admin creates accounts, user can be only a operator, no monthly bills. You can use Tool Mode for single site with own hosting for example.
To enable this mode change:
- before build open file /components/cache-remote/extra/net-props/common.properties
- or after build open file /build/_servers/chat-central-server/net-props/common.properties
- change prop 'toolMode' to true
Requirements
- Java 8
- PostgreSQL or default H2DB (included to the build)
- Windows (tested on Win7) / Linux (tested on Ubuntu)
