WAR containing spring boot app, manual deployment to openshift tomcat not working
I created a Spring Boot Application, then created a War.
On my local server, the app is working correctly.
I added this application to the JBOSSEWS cartridge by renaming it to ROOT.war, placing it in the webapps directory using git, and restarting the server.
But I always have no 404 found.
Tomcat logs:

Make sure your main class app extends SpringBootServletInitializer
Initialize servlet
By converting this to a WAR file without XML files, you need another signal to the servlet container on how to start the application.
import org.springframework.boot.context.web.SpringBootServletInitializer;
public class HelloWebXml extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
HelloWebXml
is a pure Java class that provides an alternative to creationweb.xml
. It extends the classSpringServletInitializer
. This extension offers many configurable options through method overrides.

Make sure you remove the pom.xml file and the src / directory so that it expands your ROOT.war file when you push git. You can check this kb article for more information: https://help.openshift.com/hc/en-us/articles/202399740-How-to-deploy-pre-compiled-java-applications-WAR-and-EAR -files-onto-your-OpenShift-gear-using-the-java-cartridges
I had the same problem and was able to solve it by copying the .openshift directory from the original git-repo to the tar.gz repo folder. Therefore, subsequently, the directory structure looked something like this:
myApp.tar.gz
- dependencies
- - jbossews
- - - - webapps
- - - - - ROOT.war
- repo
- - .openshift
- - - - markers
- - - - - java7
...
I think the problem in my case was that tomcat tried to deploy the application with JDK 1.6, as this seems to fallback when there is no java7 file in the markers directory ...
