In Eclipse you may get more info on errors in a Problems view tab. Windows -> Show View -> Problems. You'll see a list of actual errors. I used to get the same message "INFO: No Spring WebApplicationInitializer types detected on classpath" when importing the existing Spring project into STS IDE. In my case there were the hibernate-3.2.1.ga.jar corrupted in lib folder. Replacing it have solved all compile problems.
Seems strange to me that URL http://localhost:8080/appRoot/page.jsp
produces Directory Listing. Can you try your Tomcat server with another application which is working. The Spring WebApplicationInitializer should deal with web.xml file, where Spring is not initialized properly.
I added WebROOT file directory to the default directory, problems solved.
