Java spring app with javaagent(1.3.0) in istio result in trace break

[sanjaygopinath89]

HI All,

I have create a Java spring boot application and using OTEL java agent to generate trace from application layer . I have deployed this app in a istio service mesh . I am collecting trace from application layer and also from Envoy /Istio proxy to same backend (jaeger) . But the trace is getting break. I can see trace generated from Istio/Envoy separately and the trace generated from OTEL java agent separately, like 2 different traces . There is no link between this 2 spans.

1. How can I link the span generated from Envoy/Istio to the span generated by otel java agent , so that it will be part of a single trace

Thanks and Regards,
Sanjay

I configured "b3bulti " propagator in java application and it fixed the issue.
