Chat Form on a site:

Operators Cabinet:

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)

How to build

• download last version
• check Java version (print "java -version" in a console)
• start build.bat (win) or build.sh (linux)
• on BUILD SUCCESSFUL message see /build/_servers dir
• copy all files from /build/_servers to your work dir
• run all components by single runner: run-all.bat (win) or run-all.sh (linux)
• open browser with url 127.0.0.1:10280 for access to index page
• sign in to cabinet with admin / admin login and password
