JSON-RPC server is integrated with Quarkus.

The entry point is the module io.yupiik.uship:jsonrpc-quarkus. Once added you can:

  • implement JSON-RPC methods using beans marked with @JsonRpc and methods with @JsonRpcMethod,

  • configure the base url of the OpenRPC value using jsonrpc.baseUrl (defaults to try to use localhost and the quarkus port) and jsonrpc.binding to configure the servlet binding in microprofile-config (application.properties), it defaults to /jsonrpc.

Here is a sample:

public class MyEndpoints {
    @JsonRpcMethod(name = "reverse")
    public String reverse(@JsonRpcParam(value = "in") final String input) {
        return new StringBuilder(input).reverse().toString();

    @JsonRpcMethod(name = "header")
    public String header(@JsonRpcParam(value = "name") final String name,
                         final HttpServletRequest request /*important: se jakarta one*/) {
        return request.getHeader(name);
