Web Socket Issue

[umar farooq]

Hi All,
       I am trying to use Chat example of WebSocket given in  Tomcat version
 7.0.27. Problem I faced are here.

1) After opening the web socket it closes the socket automatically after 20
sec. I want connection open until Guest (i.e. user) explicitly closes it.
2) Second thing is that It broad casts the message to all users but what i
want is to send message to a specific group of people.
Is there any method to send message to specific group.?? I checked API for
WebSocket but there is no method for multicast.

Kindly help me I have very short time to implement it.

Thanks..

Have the client send a ping message every 10 seconds

But it is not requirement. I want to send ping once to open the socket
after that it should depend on user when he wants to close the connection.
Cannot I explicitly call some method to set timeout forever on client or
server side. Or any other mechanism..??

While the API call to set timeout is missing (it is present in Tomcat's
Comet implementation) a "forever" setting would not do you any good
Your application has to learn how to deal with disconnects, as they are very
common over WAN.
I expect that a future version will have that call, but it wont completely
solve your problem
