Please follow the steps mentioned below to enable auto instrumentation for Java.

1. Download opentelemetry-javaagent.jar from Release and place the JAR in your preferred directory.

2. Add -javaagent:path/to/opentelemetry-javaagent.jar and other params as mentioned below to your JVM startup arguments and launch your app:

   java -javaagent:path/to/opentelemetry-javaagent.jar -Dotel.metrics.exporter=none -Dotel.exporter.otel.traces.endpoint=your-otel-collector-endpoint -jar myapp.jar

3. Please add the following environment variable OTEL_RESOURCE_ATTRIBUTES="service.name=your-service-name,service.namespace=your-service-namespace"
