QUESTION
I'm developing a web-socket application in play and using actor based websocket implementation according to their official tutorial (https://www.playframework.com/documentation/2.8.x/JavaWebSockets)
In controller
...ANSWER
Answered 2020-Jan-15 at 09:04When there are missing APIs for typed (I think this is the case with the Play ActorFlow) you can adapt the new typed APIs to the classic ones using akka.actor.typed.javadsl.Adapter
, like so: Adapter.toClassic(typedActorRef)
More docs on coexisting typed and classic APIs here: https://doc.akka.io/docs/akka/current/typed/coexisting.html

I have an Play application that handles WebSocket requests. The routes file contains this line:
...ANSWER
Answered 2019-Aug-23 at 08:50The documentation indeed need to be updated, I think some bits were missed in the refactoring of the websockets in #5055.
To get async processing, you should use the acceptOrResult
method that takes a CompletionStage
as return type instead of a flow. This can then return either a Result
or an Akka Flow
, using a functional programming helper (F.Either
). In fact, here's how the accept
method is implemented:
QUESTION
I am trying to implement websockets with actors in java. The place where we accept the websocket connection and create an ActorFlow.actorRef to handle websockets, is there any way to pass parameters to the websocket actor? I am following this example from documentation here .. https://www.playframework.com/documentation/2.6.x/JavaWebSockets#handling-websockets-with-actors
...ANSWER
Answered 2018-Jul-27 at 20:25In general, passing arguments to an actor is the following :
QUESTION
I need to make an application where, while the user is authorized, it keeps the socket connection until it is logged out. For this purpose, a foreground service is created, which starts after the authorization of the user, and stops when it is logged out. It implements connection and reconnection on the socket.
All works well until you press the power button and turn off the charging. After this, the user stops receiving pongs from the server and the SocketTimeoutException is received on the OkHttp, and also stops receiving messages on the socket. On JavaWebsocket The connection was closed because the other endpoint did not respond with a pong in time.
is received, after which you can successfully create a new socket connection, but it will repeat the same problem in the loop.
In the settings, the optimization of the battery for this application was disabled. What can I do to make a stable connection socket work in the background?

ANSWER
Answered 2018-Jul-04 at 15:16After some research and testing on different devices, it was found that for stable operation on the network, it is necessary that the device is charging or has a screen enabled. In the other case, neither PARTIAL_WAKE_LOCK
nor the disabling of battery optimization in the settings itself can solve the problem.
The recommended way to solve this problem is to add this code to your activity:

I'm wondering if specifying the type of messages handled by your websocket would fix the problem, try:

Install JavaWebSocket
You can use JavaWebSocket like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the JavaWebSocket component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
