error and problem in Quickstart: Create a Java app on Azure App Service

Question

I am trying run this sample in web apps by portal azure.

link of quickstart:

https://learn.microsoft.com/en-us/azure/app-service/quickstart-java?tabs=javase&pivots=platform-linux-development-en

The deploy is successful, but the home returns that "Hey, Java developers! Your app service is up and running. Time to take the next step and deploy your code."
Any clue ?

I restart the service many times.

I redeploy many times.

But this sample just runs in Azure Spring Apps (but this servide is deployed in a longer URL (not practical) and without database.

Any clue to run this Quickstart in App Service, instead Azure Spring Apps ????

here is the log....

@Rogerio Tadeu de Oliveira Lacerda Thanks for reaching here! If I am understanding right you are when deploying java app from Azure portal the deploy was successful but returning homepage only-

"Hey, Java developers! Your app service is up and running. Time to take the next step and deploy your code."

could you try to add as below to the azure-webapp-maven- plugin configuration in your POM file.

<appSettings>
    <property>
        <name>JAVA_OPTS</name>
        <value>-Dserver.port=80 -Dsite.root=/usr/local/appservice/parkingpage/ROOT</value>
    </property>
</appSettings>

Additionally,

Suggest you to inspect the log files in a browser at https://<app-name>.scm.azurewebsites.net/api/logs/docker.
