Azure Web-app .WAR File deployed to TOMCAT give 404 ERROR

Question

I have created a Microsoft azure web app and configured java version 8 and tomcat 9 (Auto update). As per their documentation , I have uploaded my WAR file using KUDU in the web-app folder (ROOT.war my file name).

When I created the web-app without the deployment it did render the home page as Java TomCat Ready and as soon as I have deployed the ROOT.War file in my new Resource group it is now giving me 404 error.

The sub-status is 404 -"0" and I am not sure what has gone wrong the same deployment was working yesterday in the same resource group and now if I try to browse the URL of my web-app I get 404 error. I have done all sorts of research and trials but no help. Can someone help me where I can find n fix this one?

Answer 1

Hi 

It looks like the deployment has failed. Can you test the deployment using https://github.com/projectkudu/kudu/wiki/Deploying-WAR-files-using-wardeploy.

Please enable the diagnostics logs so that we can check the catalina log and localhost log. 

It should be under: D:\home\site\LogFiles\Application. 
Catalina log will show it there were any errors during deployment; ideally there shouldn't be any errors here

Thank you Dashleen,

I had deployed using wardeploy (AZ CLI) as well but same thing. Finally something came to my help and that was the CATLENA LOGS under the Logs (using KUDU portal)-->> Application Logs.

Issue was with the DATABASE Connection to my Azure Postgres SQL which had SSL REQUIRED enabled. The Application settings for the WAR File web-app needed the SSL setting in the connection string. Fixing that fixed my issue.

NEEDED the SSL=TRUE

${POSTGRES_URL} =.

jdbc:postgresql://abcd-corp-chatbotpgsql.postgres.database.azure.com:5432/chatbotsqldb?ssl=true&sslfactory=org.postgresql.ssl.NonValidatingFactory

Thanks Ana for the clarification.

Glad to know that Catalina logs helped you find the root cause.
