WS Java API does not support for optional path parameters, you can't
achieve above using one WS endpoint instead you need to write two endpoints
as follows.
@ServerEndpoint(value = "/t/{tdomain}/{topic}")
@ServerEndpoint(value = "/{topic}")
BTW please don't duplicate same logic in both classes instead move logic
into common abstract or util class.
Thanks !
