I have not put tomcat 7 .jar in libs. I've used plugin for this in pom.xml and ran mvn package and mvn install from command prompt. It has build successfully but when I run it using Maven in Eclipse and try to open http://localhost:8080/WicketFirst , it throws above mentioned error.

Answer 1

Tomcat 7 supports Servlet API 3.0. For Wicket 8 you need to use a container which supports at least Servlet API 3.1, which would be Tomcat 8 or higher.
