Hi, have you solved your 404 error? I meet the same problem. After mvn install the project and deploying the war file in tomcat 7, the 404 error occurs when accessing the web page.

[zAbuQasem]

Yes, i remember i solved it but i don't remember how. it's been almost 2 years

Hi, do you remember where to set username manager@email.com and password 123456?

Hi, i have solved the problem. The 404 error is caused by the failing database lms creation. I create lms in psql shell with the "psql -U postgres lms < app-DB-Script.sql". It fails with not any notification.

Hi, I got the same 404 error, but I believe I am able to create lms database since I can check its content via PostgreSQL. Any idea about how to debug?
