Spring app works locally but not on Azure

Question

I've got a problem with deploying my Maven application on the Azure web service. Locally everything works alright, the pipeline's working, and app is deployed, however, whenever I try to see page content on azure websites the response is:

:( Application Error
If you are the application administrator, you can access the diagnostic resources.

Of course, I checked azure logs and that's what I've observed:

I had problems with servlets before, but with exclucions I was able to remove error below:

Caused by: java.lang.NoSuchMethodError: 'java.lang.String javax.servlet.ServletContext.getVirtualServerName()'

The occurring of this problem is very confusing to me and honestly, I am out of ideas on how to fix this.

Below, I attach POM.xml and azure.yml:

I've read this page before and I handled servlets, using exclusions, and right now the app is running normally, but only locally. — Piotr Jaśkowiec, May 15 '21 at 16:29

Check application logs like below.

You will find you missing startup command. In logs, it will show you like below:

2021-05-16T16:07:34.95**Z No STARTUP_FILE available.
2021-05-16T16:07:34.95**Z No STARTUP_COMMAND defined.
2021-05-16T16:07:35.01**Z Made a local copy of the app and using APP_JAR_PATH=/local/site/wwwroot/app.jar
2021-05-16T16:07:35.01**Z Running command: java  -Dserver.port=80 -jar /local/site/wwwroot/app.jar

So you can add startup command to slove the issue.

Yes, you located the source of my problem, but the next problem has appeared after that. The azure is unable to access jarfile /local/site/wwwroot/app.jar. Do you have any idea how to fix this one? – Piotr Jaśkowiec May 23 '21 at 17:12
The path should be /home/site/wwwroot/app.jar . – Jason Pan May 24 '21 at 00:08

Spring app works locally but not on Azure
