I have simple application on Spring MVC which runned on tomcat 7.0.72 in IDEA. How can I run this application on Heroku (if it's possible). I have Heroku account and I did create app on it. I use Maven for deploy and Git for push it in Heroku. Files of app will be below. So, when I run it on localhost by tomcat it works. But when I push it on heroku I get it:

Application Error:

An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.

There are (at least) two deployment styles for Java web applications:

The first is detailed here:

https://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat

The second is detailed here:

https://devcenter.heroku.com/articles/java-webapp-runner

You seem to have mixed elements of both mechanisms in your POM: for example the webapp-runner is only required in the second style.

Remove these conflicts and check the configuration.

So, I can't create app which can be run in IDEA by tomcat and on heroku?
I try to do it in second way.
You can deploy from IDEA : devcenter.heroku.com/articles/… OR read spring boot in action chapter 8
I want to buid app with Spring and mapping but not on servlets
