How to use Jaeger with Helidon Microprofile

Question

I have created a Helidon Microprofile quickstart project from helidon.io get started while configuring with Jaeger I am unable to find the Trace in Jaeger UI below are the steps which I have followed:

1. Created project using

   mvn archetype:generate -DinteractiveMode=false \
       -DarchetypeGroupId=io.helidon.archetypes \
       -DarchetypeArtifactId=helidon-quickstart-mp \
       -DarchetypeVersion=1.4.4 \
       -DgroupId=io.helidon.examples \
       -DartifactId=helidon-quickstart-mp \
       -Dpackage=io.helidon.examples.quickstart.mp
   

2. Updated pom.xml with Jaeger dependencies

   <dependency>
       <groupId>io.helidon.tracing</groupId>
       <artifactId>helidon-tracing-jaeger</artifactId>
   </dependency>
   <dependency>
       <groupId>io.jaegertracing</groupId>
       <artifactId>jaeger-client</artifactId>
       <version>0.32.0</version>
   </dependency>`
   

3. Updated GreetApplication

   @Traced
   @ApplicationScoped
   @ApplicationPath("/")
   public class GreetApplication extends Application {......}
   

4. Updated /helidon-quickstart-mp/src/main/resources/META-INF/microprofile-config.properties

    #Jaeger properties
   tracing.service=mp
   

5. Executed mvn package and then target>java -jar helidon-quickstart-mp.jar

6. Now in my Jaeger UI I am unable to trace the running Service:

   

So how can I configure Jaeger UI to my helidon Microprofile project?
