Would like to know if Sending remote notification payload to Apple’s new HTTP/2 API service can be supported with Java 1.6. If yes, how to support the same?
Thanks

I'm trying to analyse what information an app is sending so I setup Charles but to my surprise nothing was logged out.
After decompiling the app I see that it doesn't use simple REST calls but rather a library called gRPC.
Is there a good tool out there that will allow me too see what is send out from the app?
The Mediator is a Cross-platform GUI gRPC debugging proxy like Charles but design for gRPC.
You can dump all gRPC requests without any configuration.
Mediator can render the binary message into a JSON tree, when you have the API schema.
It support decode gRPC/TLS, but you should download and install the Mediator Root Certificate to your device.
gRPC uses HTTP/2 as a transport protocol. Any proxy which supports HTTP/2 for both the front-end and back-end connections should be able to be used to inspect the packets a gRPC connection. Note, some proxies only support HTTP/2 for the front-end or back-end connections and those are incompatible with gRPC.
Envoy Proxy (https://www.envoyproxy.io/) supports proxying gRPC connections and can be configured to log out request information.
Some other example proxies include:

If you are asking for android there is a app called HttpCanry. It can log request/ respond.
I am developing an Android video streaming application using the OkHttp library and HTTP/2. I am investigating the possibility of using the server push functionality of the HTTP/2 protocol, but I am not sure whether OkHttp supports it or not.
I have a basic server implementation to test HTTP/2 push, which works without problems on the chrome browser (i.e., pushed content is stored in the cache and retrieved from the cache by the browser). When I use the Android application with the OkHttp library, content is not pushed anymore to the client's cache (which is initialized and working properly, by the way). Particularly, the client sends a reset stream to the server for each content the server would like to push.
Do you have any idea if OkHttp supports push streams? And in case it does support server push, are there any best practices to make it work? Thanks in advance for your answers.
Nothing currently. We’re rewriting the cache persistence and that’s a big effort. If you want to read the internals there’s callbacks for it, but they currently just cancel the pushed streams.
I noticed that WSO2 5.0 released new functionality - websockets. I have familiarized a little bit with these tutorials:
WebSocket Support
I see that it is possible to send messages from client to WSO2/Backend via WebSockets, but I did not understand if revers communication is available - from WSO2 to client via WebSockets.
I would like to read the message from RabbitMQ in WSO2 ESB and send that message to the JavaScript client connected to the WSO2 via WebSocket.
I will appreciate any code examples.
Thank you in advance!
By assuming your jvascript as a web socket endpoint, you can merely use web socket sender [1] to send the message there.

I am trying to find out if Ibm ISAM/Webseal supports the websocket protocol. I've tried to google for it, but with no success. Does anyone of you know if it does and if it needs any configuration to support it?
ISAM 9.0.2.0 supports the WebSocket protocol. ISAM 9.0.2.0 should be released in November 2016.
ISAM will happily take and deal with most packets that are HTTP formatted. WebSockets however are not supported.
Microsoft describes a method to create a push notification service in C#.
But I rather want to run a Java service for this is that possible at all?
Absolutely. It's just a matter of making an HTTP/HTTPS request to Microsoft. MSDN shows the headers and payloads to be sent.
