I don't know this framework, so just throwing suggestions:

For tracing your methods, use the [public API](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html).

For tracing library methods, use the [`trace_methods`](https://www.elastic.co/guide/en/apm/agent/java/current/config-core.html#config-trace-methods) configuration, but please try to be very specific and explicit in what you want to trace with it.

In order to utilize [Elastic APM's Distributed Tracing](https://www.elastic.co/guide/en/apm/get-started/current/distributed-tracing.html) capabilities, you would have to add a trace context on the client side and read it at the server side. You will need to find interceptors for both client and server, and assuming you can add arbitrary context to requests as metadata, you need to set the trace context at the client interceptor through [`injectTraceHeaders`](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-transaction-inject-trace-headers) and extract it at the server interceptor through [`startTransactionWithRemoteParent`](https://www.elastic.co/guide/en/apm/agent/java/current/public-api.html#api-start-transaction-with-remote-parent-header).

I hope this helps,  
Eyal.

Please don't use multiple topics for the same question, this is causing a non-required overhead.
