the problem when try call servlet @ http://localhost:8080/mahlzeitserver/helloworld/hello getting response tomcat:
http status 404 - /mahlzeitserver/web-inf/helloworld.jsp type: status report message: /mahlzeitserver/web-inf/helloworld.jsp description: requested resource not available. i'm note sure why case. if go localhost:8080/mahlzeitserver site gets displayed ${msg} not replaced. here index.jsp file:
<html> <body> <h2>hello world2!</h2> <h3>your message : ${msg}</h3> </body> </html> helloworldcontroller.java
package com.mahlzeit.server; import org.springframework.stereotype.controller; import org.springframework.ui.modelmap; import org.springframework.web.bind.annotation.pathvariable; import org.springframework.web.bind.annotation.requestmapping; import org.springframework.web.bind.annotation.requestmethod; @controller @requestmapping("/helloworld") public class helloworldcontroller { @requestmapping(value = "/hello", method = requestmethod.get) public string hello(modelmap model) { model.addattribute("msg", "jcg hello world!"); return "helloworld"; } @requestmapping(value = "/displaymessage/{msg}", method = requestmethod.get) public string displaymessage(@pathvariable string msg, modelmap model) { model.addattribute("msg", msg); return "helloworld"; } } mvc-dispatcher-servlet.xml

looks case issue. try
@controller @requestmapping("/helloworld") public class helloworldcontroller { ... instead of
@controller @requestmapping("/helloworld") public class helloworldcontroller { or try hitting
http://localhost:8080/mahlzeitserver/helloworld/hello instead of
http://localhost:8080/mahlzeitserver/helloworld/hello
