That would certainly be the place to start.  I don't know anything about web sockets in tomcat, do you have to configure tomcat to turn on the support?  Geronimo rewrote the tomcat configuration mechanism so most likely the method of configuration would have to be added to the geronimo config code.

hi,David. Tomcat support WebSocket from 7.0.27. The Tomcat in Geronimo 3.0.1 is 7.0.39. So it means geronimo can support WebSocket. Just there are some work in geronimo side to do, such as geronimo-tomcat7 module. Right?

Thanks David,

Can you please provide some guide on how to go about doing the integration? Excuse my apparent ignorance, but this area is completely new to me.

1. where/which/what are the integration points for tomcat?
E.g any initialization/routines/library calls aside the vanila tomcat itself?
2. Gotchas to be aware of
3. Tips to ensure standards compliance

Many thanks

I don't think anyone is actively working on the geronimo server at the moment (happy to be
proven wrong….). Options I can think of are:

- integrate a more recent tomcat yourself, hopefully providing patches.

- use karaf with jetty

We are doing osgi development on geronimo 3.01 currently and we need to be able to use websocket. We understand the current tomcat bundled with geronimo does not have websocket implementation. So we'd like to know what the plans are to make websocket available in geronimo.
If it's not any time soon, could you please advise what alternatives we can consider.

Many thanks
