Solution: the reason why my JSP files couldn’t be found was that I started the project entirely from scratch. However, if you want to deploy to Openshift you require Openshift’s .openshift folder that contains the default configuration for the Tomcat cartridge. The problem had nothing to do with my web.xml and servlet definitions.
I am currently building a new webapp from scratch using Spring Web MVC. Spring, Spring Web MVC and a few Java concepts like annotations are new to me.
The fact that my app’s codebase is currently based on a non-standard example I plucked from the web is not making it any easier.
Right now the app deploys and runs correctly on a Tomcat 7 fired up from within IDEA, the JSPs can’t be found after deploying to Openshift.
It’s very likely related to following strange web.xml and servlet definitions:
web.xml
...
<servlet>
<servlet-name>analyzer</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet-mapping>
<servlet-name>analyzer</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
...analyzer.xml
...
