Answer 1

"java.lang.Error: Unresolved compilation problems: "

says that application is not compiled properly. Please put the servlet-api.jar in classpath, not just in lib folder of project, but also attach that to classpath.

Please make sure that same jar also available in tomcat/common/lib folder.
