[FIXED] Spring app works locally but not on Azure

January 14, 2022 azure-web-app-service, deployment, java, maven, spring

Issue

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:

Solution

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.
