Spring Boot application runs normally on embedded Tomcat server when I run it from Eclipse, but when I deploy it to external tomcat server (on Linode VPS running Ubuntu) I'm getting HTTP 404 status.
It's currently only backend part of app (if it matters at all), so I don-t have any index.html or anything like that in root folder of app. But in postman, or through links I'm getting responses normally when run locally.
I've tried everything that people recommend and still don't know where the problem is.
- There are no exceptions in tomcat when app is being deployed
- Tomcat manager works normally and shows that the application is up and running
- I'm building this app with Maven with clean install with java version 11. Tomcat is version 10.
- I've done everything from this link When Spring Boot app is deployed on tomcat gives 404 error
On embeded tomcat I can get Json with this url: http://localhost:8888/gallery/autori
On remote tomcat manager works like it should:
http://xx.xx.xxx.xxx:8080/manager/html/
but my application is not working. I've tried different urls
http://xx.xx.xxx.xxx:8080/gallery
http://xx.xx.xxx.xxx:8080/gallery/autori
http://xx.xx.xxx.xxx:8080/gallery/gallery/autori
I've tried those different urls because in application.properties I have server.port and context-path defined (even though it doesn't matter on remote server, it-s only for embeded tomcat, as far as I know). Also I tried without those two defined ofcourse...
server.port=8888
server.servlet.context-path=/gallery

Here is my starter application:
@SpringBootApplication
public class GalleryApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(GalleryApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(GalleryApplication.class);
}
}

I now see that tomcat uses OpenJDK 11 and not OracleJDK 11. COuld that be the source of problem? Please help!
