With the current implementation? No. Writes are always blocking. They should time out at which point you can drop the connection. But that isn't going to be pretty. > Can I detect if a sending buffer is full? No. > Can I set its size? Yes. > Can I register a notification to be notified when there is space in the > sending buffer? No. The in-progress WebSocket JSR has an API that uses non-blocking IO throughout so the answers to all of the above questions will become yes. As the Tomcat implementation of this develops, it will almost certainly be back-ported from Tomcat 8 to Tomcat 7.
