Using OpenTelemetry and JaegerUI with SpringBoot 2.5 - spring-boot

Question

I'm trying to build a monitoring system for a Springboot application. I need to send some metrics to an OpenTelemetry collector and then to Jaeger.
I'm setting up Jaeger and OpenTelemetry via docker compose, these are my docker-compose.yml and otel-collector-config.yml
version: "3.3"
services:
otel-collector:
image: otel/opentelemetry-collector:latest
command: [ "--config=/etc/otel-collector-config.yaml" ]
volumes:
- ./otel-collector-config.yaml:/etc/otel-collector-config.yaml:Z
ports:
- "13133:13133" # Health_check extension
- "4317:4317" # OTLP gRPC receiver
depends_on:
- jaeger-all-in-one
jaeger-all-in-one:
image: jaegertracing/all-in-one:latest
container_name: jaeger-all-in-one
ports:
- "16686:16686"
- "14268:14268"
- "14250:14250"
receivers:
otlp:
protocols:
grpc:
endpoint: otel-collector:4317
exporters:
jaeger:
endpoint: jaeger-all-in-one:14250
tls:
insecure: true
processors:
batch:
extensions:
health_check:
service:
extensions: [health_check]
pipelines:
traces:
receivers: [otlp]
processors: [batch]
exporters: [jaeger]
Also, these are my pom.xml dependecies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-sleuth</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-brave</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-sleuth-otel-autoconfigure</artifactId>
</dependency>
<dependency>
<groupId>io.opentelemetry</groupId>
<artifactId>opentelemetry-exporter-otlp-trace</artifactId>
</dependency>
<dependency>
<groupId>io.grpc</groupId>
<artifactId>grpc-okhttp</artifactId>
<version>1.42.1</version>
</dependency>
And i put in application.properties:
spring.application.name = myName
sleuth.enabled= true
sleuth.otel.exporter.otlp.endpoint= http://localhost:4317
If I try to start the application I see that tracing is active and traceId and span are logged, but Jaeger does not receive anything, and the service is not even displayed.
I'm running out of ideas...
