Do you use the JRPC protocol in your projects?

JRPC (JSON-RPC) is a simple remote procedure call protocol that uses JSON for message encoding. In Java projects, it is used when a lightweight and fast interaction between client and server is needed without complex overhead.

For example, if you have a microservice architecture and need a simple way to invoke methods on another service via HTTP, JSON-RPC can be a convenient choice.

However, in most cases in Java projects, REST or gRPC are more common and supported.

If the project requires a lightweight protocol with minimal setup and JSON format, then JRPC is quite applicable.
