Title Body

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 maven. For instance, some provide the addServlet() method and some do not. Here is my config class: public class MyWebAppInitializer implements WebApplicationInitializer { @Override public void onStartup(ServletContext container) throws ServletException { AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); rootContext.register(JpaSandboxConf.class); ServletRegistration.Dynamic registration = container.addServlet("dispatcher", new DispatcherServlet()); registration.setLoadOnStartup(1); registration.addMapping("/myapp/*"); } } Which seems rather uncontroversial. In order to get the container.addServlet() method, I included this in my pom: <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-servlet-api</artifactId> <version>7.0.30</version> </dependency> I tried this, but the ServletContext class from the entry below DID NOT WORK (in that it didnot provide the addServlet() method): <dependency> <groupId>javax.servlet</groupId> <artifactId>com.springsource.javax.servlet</artifactId> <version>2.5.0</version> <scope>provided</scope> </dependency> When I attempt to run this using mvn clean tomcat7:run I unhappily obtain SEVERE: A child container failed during start java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Tomcat].StandardHost[localhost].StandardContext[/]] at java.
