SemiSpace has a module which allows JavaScript to communicate to an cometd-enabled webserver. The javascript interface mimics the Java interface as closely as possible.
We are presently using Cometd-2.x.
The semispace-comet module of SemiSpace consists of the following parts:
| semispace-comet-server | The webapp which will answer the JavaScript queries |
| semispace-comet-client | An emulation of the JavaScript client behaviour. Can be used for emulating a client for test purposes, or for bridging two server implementations |
| semispace-comet-common | Transport objects and functionality shared between the client and server implementation |
| semispace-comet-webapp | An example webapp, which gives you inspiration of how to configure your own |
| semispace-comet-app | A standalone jetty server which you can easily run on the command line |
| JavaScript | The web client functionality resides in JavaScript which you simply downloaded and add to your webapp |
When using semispace-comet, you need to install / prepare the server side and the JavaScript side. On the server side is a matter of setting up the webapp with dependencies in a manner similar to semispace-comet-webapp (which indeed is an example). On the client side, you need to copy down the JavaScript files, and put them in the correct directories.
A good starting point is to examine the projects in semispace-comet, and semispace-comet-webapp in particular. That sub project contains examples of use.
