Hi all,
I just *built* a websocket sample [3], using java-6. Build was successful.
However as Kasun has mentioned, if we *run* using java-6, tomcat-websocket
features (i.e. Tomcat JSR-356 Java WebSocket 1.0 implementation) don't
work.
This is also being mentioned in [4]
> "The JSR-356 Java WebSocket 1.0 implementation is only available when
> Tomcat is *running* on Java 7 or later."
Accordingly, I get this message at CEP server startup, when using java-6.
[2014-07-08 14:10:15,948] INFO - {WsSci} JSR 356 WebSocket (Java
> WebSocket 1.0) support is not available when running on Java 6. To suppress

Thanks Kasun & Mohan for helping to try out websocket samples.

Dilini
