Maven Project - Click on Tomcat, but do not run

Question

I have a project from Maven which, although the messages displayed on the Eclipse terminal inform that the Deploy was successfully done. When I type the URL into the browser, I get a 404 error; then when opening the manager of Tomcat, I try to start it, but I also get an error.

Eclipse terminal output, operation of deploy:

Does anyone have any idea what’s wrong with the project?

Answer 1

Well, after further testing, I discovered that the mistake was in one of my classes. One of the attributes of this class was with the wrong type, and so the system could not load this attribute on application startup (the attribute had the Autowired annotation).

I discovered this by running Tomcat from the terminal, and tracking its exit. That’s because I couldn’t find a way to get this output to be displayed on the Eclipse console.
