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.

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.

Stenbeeke: I replaced "tomcat7-maven-plugin" with "tomcat8-maven-plugin". Again, I was able to build using Eclipse as well as using Command Prompt : mvn compile, mvn package. I'm also getting WicketFirst-1.0-SNAPSHOT.war file in target folder of my project "WicketFirst". But don't know, how to run it. How to see the output in browser. I also installed tomcat 8 separately, ran it and tried to launch "localhost:8080/WicketFirst" OR "localhost:8080/WicketApplication". But with no avail.

When you package the application it ends up in your target folder, but not your Tomcat install. Have you tried mvn tomcat8:deploy? This should deploy the application on your local Tomcat instance (some additional config may be required). Alternatively, you can run mvn tomcat8:run-war to run an embedded Tomcat server. Disclaimer: I generally use Jetty or Wildfly so I'm not an expert on Tomcat
