Java WebSocket API availability in Tomcat 7

+1 vote

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.

I'm trying to figure out how to get access to the cookies and headers passed up in the Websocket handshake request on Tomcat 8.

In Tomcat 7 the whole HttpServletRequest was passed into the WebSocketServlet. createWebSocketInbound method so it was easy to grab from the request headers. In Tomcat 8 the querystring and URI are both exposed by the javax.websocket.Session passed to ServerEndPoint.onOpen, but I don't see a mechanism for getting the cookies or headers.

We are integrating Websocket connections into an existing web app and want to use the cookies set by our web app in the Websocket connection process.

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?

As we start load testing our jsr-356 applications, I'd like to find out if there are any websocket-specific connector settings we should be aware of for tuning the underlying websocket connection processing. Since this is a tcp socket at the end of the day, I'm assuming all the socket.* options still apply if needed.

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'm receiving the following exception:

java.net.SocketException: "Permission denied": connect

when instantiating a Socket from a servlet:

final Socket smtpSocket = new Socket(mailTransportHost, mailTransportPort);

This application was running as a service under Windows Server 3003 R2 32-bits. After migrating it to Windows Server 2008 R2 64-bit, I cannot longer establish connection with the smtp server.

This only happen when running Tomcat as a service. Running as a standalone (starting it up using startup.bat) works fine. No exception instantiating Socket, emails are sent.

Environment:

 - Windows Server 2008 R2 64-bit
 - Tomcat 7.0.39
 - jdk1.6.0_33-x64
