Helidon With Pratik

Hi Folks, Today I'm sharing my learning on "Oracle Helidon MP - Basic Authentication". Basic Authentication is a easy concept by which we can authenticate and authorise a user based on his credentials and roles. Step 0: Without Authentication. Step 1: Add maven dependencies.           < dependency >      < groupId > io.helidon.microprofile </ groupId >      < artifactId > helidon-microprofile-security </ artifactId > </ dependency > < dependency >      < groupId > io.helidon.security.providers </ groupId >      < artifactId > helidon-security-providers-http-auth </ artifactId > </ dependency > Step 2: Add Authentication & Authorisation Annotations. import io.helidon.security.annotations.Authenticated ; import jakarta.annotation.security.RolesAllowed ; @Authenticated         ...

  Hello Folks, Today I'm sharing my learning on "Tracing Helidon Application with Zipkin". Tracing is a easy concept where where we can trace our application request-responses. Step 1: Add maven dependencies. < dependency > < groupId > io.helidon.microprofile.tracing </ groupId > < artifactId > helidon-microprofile-tracing </ artifactId > </ dependency > < dependency > < groupId > io.helidon.tracing </ groupId > < artifactId > helidon-tracing-zipkin </ artifactId > </ dependency > Step 2: add one statement in microprofile-config.properties tracing.service = first- app Step 3: Fire a http request on your browser or Postman to get to application registered on zipkin. Step 4: open browser with http://localhost:9411/ select the drop-down "service name" thank you :)

 Hello Folks, Today I'm sharing my learning on "Profiling in Oracle Helidon". Profiling is a easy concept where where we can keep multiple files are per our environment and execute the application accordingly. Here we will see the changes in datax variable in profiling. Profiling can be achieved in two ways i.e. 1. yml file 2. command prompt In both scenarios we need to keep multiple profiling file (microprofile-config) I've kept three files. microprofile-config.properties microprofile-config-uat.properties microprofile-config-prod.properties I'll demonstrate both the scenarios 1. yml file with prod profiling 2. yml with uat profiling to test the application, I've created a demo controller. save the project and perfrom, 1. mvn clean install 2. java -jar name_of_the_application.jar                                                   ...
