Draft Methods

[richardwei6]

Will Draft methods such as RADIO/DISH ever be implemented into JeroMQ? I originally wanted to use JZMQ but had problems installing it. If it won't be implemented, how would I start adding it to JeroMQ? Thanks.

hi,

RADIO/DISH sockets are already available in zmq package, in the latest SNAPSHOT. I just made a PR to include them in org.zeromq as well.

[richardwei6]

Thanks for letting me know! Here's the pull request for reference: #868

Ok, so I have a new issue with the draft implmentations. When using the udp protocol, I'm getting the Protocol not supported exception being thrown when trying to connect to this address: udp://224.0.0.1:28650. Is it possible that this is not implmented? If so, how would one go about implementing it? @fredoboulo

I wonder if that try could help: https://github.com/fbacchella/jeromq/commits/networkprotocolserviceprovider
It allows to provide protocol as Services: https://www.baeldung.com/java-spi

Ok, I've merged your branch with the main branch of this repo to create this repo: https://github.com/richardwei6/jeromq. This repo contains your "networkprotocolserviceprovider" branch.

On my android studio project, I'm using jitpack to use external Github libraries from here: https://stackoverflow.com/a/34963958.

However, when trying to compile the repository mentioned above, it's getting a build error found at the end of these logs: https://jitpack.io/com/github/richardwei6/jeromq/master-v0.5.2-g3a23566-182/build.log.

Specifically, here is the small section that describes it:

I'm assuming that the reason is that these sockets aren't implemented yet in jeromq?

[richardwei6]

Ok so I tried manually merging it and I managed to get it to compile without any errors. The version is now v0.5.8. You can find it here: https://jitpack.io/#richardwei6/jeromq and https://github.com/richardwei6/jeromq

The issue is, I'm now still getting Protocol not supported when trying to bind the address.

[fbacchella]

yes, it does not implement protocol, but it reduce the amount of code to written, it's juste a simple class, that can even be added at runtime. So different implementation can be used for Android or server. It also allows to easily add unix sockets for people running on Java 16.

I'm still a little confused, what is this class you're talking about? I've looked up how to implement UDP in Java and found this: https://www.geeksforgeeks.org/working-udp-datagramsockets-java/. Is this the class you're talking about? If so, how would I go about implementing this?

[somdoron]

@richardwei6 UDP is not yet implemented in JeroMQ, what @fbacchella suggests an easier way to add UDP support.

If you want I can try to give you guidelines (and support) on how to port it to JeroMQ (I added the UDP protocol to libzmq)

Yea that would definitely be helpful!
