WebSocket enables bidirectional communication in real time over the web.
WebSocket can be run together with a normal HTTP server. You can click a button in a web browser, and enable a GPIO on your Raspberry Pi which turns on a light in your house. All in real time, and with communication going both ways!

I'm trying to use the Tomcat8 jsr client functionality in a standalone java client. I'm trying to use the minimal number of jars, so I gabbed websocket-api.jar ONLY. When I call ContainerProvider.getWebSocketContainer(), it returns null. Do I need another jar to resolve this on the client?

Is it true that current servlet-based websocket implementation will be deprecated due to the implementation of the JSR-356. We are currently implementing a Tomcat 7-based websocket server implementation that we hoped could scale up to at least 50K concurrent connections [or more], but are concerned if there are any known issues and/or limitations with the websocket implementation in Tomcat 7.

We are currently trying to test how high Tomcat 7 will scale with regards to the maximum number of concurrent websocket connections, but have already hit some problems with only 200 concurrent connections. Perhaps it's our multi-threaded client, or Tomcat configuration - not sure at this point. We have the Tomcat Connector configured with maxConnections=50000 and maxThreads=1000, so 200 concurrent connections shouldn't be a problem.

If anyone could elaborate on the Tomcat 7 servlet websocket implementation stability from a highly concurrent aspect that would be great. Additionally, if anyone has achieved 10(s) of 1000(s) of concurrent websocket connections with Tomcat 7, can you share how Tomcat was configured, what OS it was running on, and what client library you used in testing this?

I would like to use the Java API for WebSocket (JSR 356) in Tomcat 7. It is currently available in Tomcat 8 and its implementation is in a very good shape. I have performed some stress and scalability testing to verify that.
