Java client to connect to SignalR?

Question

I'd like to connect to a SignalR-server from a java client. Is that possible?

Has anybody written a java-client to connect to SignalR?

+1. Thought about that in context of writing an Android native app, but I guess there's no Java client atm. – Geoid

Too bad. Using it to build Android apps would be great! – Stupa

Unfortunately, Java is not my native language. :) Do you know where I can find a description of the protocol used by SignalR? – Stupa

I don't think there is a full description anywhere. It's changing quite frequently, so IMO there won't be a complete one before 1.0 airs. But having a brief description of at least the negotiation process and one of the transport methods would be good enough to have... – Geoid

We'll start documenting the protocol pretty soon. – Dory

As an option you can use the Javascript client and access it from Java through DWR. – Sabah

Another option would be expose .Net client as a SOAP-based webservice and access it from Java (JAX-WS) – Sabah

Have you had a look at github.com/SignalR/SignalR/wiki/SignalR-JS-Client-Hubs or have you found a good solution in the meantime? – Skylar

I didnt find a solution so I started to develop one by myself. See my answer below. – Stupa

Answer 1

I didnt find a SignalR-client for Android so I started to develop one by myself. You can checkit out at https://github.com/erizet/SignalA. Curently it's more like a proof-of-concept than a finnished library. It's now updated to protocol version 1.2 which is used in the 1.0 release of SignalR.

Hey Erik, I am in need of SignalR client for Java and I saw SignalA but the problem is that it does not (yet) support Hubs. Can you advice me what are my options? – Gayden

I'm thinking of implementing Hubs...maybe. Another option is that you implement Hubs and contribute to the project. :) – Stupa

Is there any tutorial available for the implementation of SignalA on Android? – Perennial

Answer 2

Microsoft has just released a java client https://github.com/SignalR/java-client even an Android client.

Thanks for the link! I've written a short tutorial to get started with this client, since the documentation still seems limited. – Twinberry

Great material, Steven! – Efrainefram
