SpringServletContainerInitializer cannot be cast to javax.servlet.ServletContainerInitializer

Question

I am attempting to move a xml-based Spring MVC app to a Java Configuration based app. There appears to be a mismatch with the various java.servlet classes available in mave

Answer 1

I had a similar problem without Spring, where mvn tomcat7:run did not work, despite the servlet deploying to OpenShift just fine. As per Biju Kunjummen's answer, the problem for me was which servlet-api I was compiling against.

Broken:

    javax.servlet
    javax.servlet-api
    3.0.1
    provided

Fixed:

    org.mortbay.jetty
    servlet-api
    3.0.20100224
    provided

Not terribly sure why, but it works now.
