how can i do this time...
i have no idea ,pls help me
OpenTelemetry uses 16-byte trace IDs and 8 byte span IDs, which is consistent with the w3c trace context format for its default trace context propagation mechanism.
If you are using the OTel java api/sdk and wish to send traces using B3 context propagation, you can leverage the B3Propagator.
The version of Brave you are using is quite ancient (~8 years old, predates the OpenTelemetry project). 😁
