Support for ZMQ.DISH and ZMQ.RADIO Sockets in jeromq

[thstasy]

Hello jeromq Developers,

I am working on a project that requires ZeroMQ's UDP socket types (ZMQ.DISH and ZMQ.RADIO). While I see that these sockets are supported in the C++ version of ZeroMQ (introduced in version 4.2), I am encountering a compilation error in Java when attempting to use ZMQ.DISH.

The error message is as follows:
[ERROR] /path/to/ZmqTmDataLink.java:[19,39] cannot find symbol [ERROR] symbol: variable DISH [ERROR] location: class org.zeromq.ZMQ

I've updated to the latest version of jeromq, but the issue persists, suggesting that jeromq may not yet support these UDP-based socket types.

Could you please confirm whether ZMQ.DISH and ZMQ.RADIO are currently supported in jeromq? If not, is there any plan to include support for these socket types in future releases? Additionally, is there any recommended workaround for using ZeroMQ over UDP in Java?

Thank you for your assistance!

Best regards,
Tsai-Hsuan Stasy Hsieh

Can you show the offending line ? UDP is indeed not supported, but RADIO/DISH is: https://github.com/zeromq/jeromq/tree/master/jeromq-core/src/main/java/zmq/socket/radiodish

Oh sure, I'll reproduce it ASAP on Monday. Thank you!

Hi,

Thank you for your prompt response!

Here is the offending line(underlined in blue), and the error message log screenshots:


And I guess I have already updated jeromq version to the latest ones, correct me if I am wrong:

Screenshoots are not very usefull to search for text.

If you look at the source code: https://github.com/zeromq/jeromq/blob/master/jeromq-core/src/main/java/org/zeromq/ZMQ.java

You can have a look at https://github.com/zeromq/jeromq/blob/master/jeromq-core/src/main/java/org/zeromq/SocketType.java.
