java - annotation configuration - how to say spring configuration class location -

spring doesn't see request mapping controller. try use annotation configuration without xml.

project structure:

config.java

package com.dnn.web.config; //imports @configuration @componentscan("com.dnn.spring")    @enablewebmvc public class config {         @bean     public urlbasedviewresolver setupviewresolver() {         urlbasedviewresolver resolver = new urlbasedviewresolver();         resolver.setprefix("/web-inf/views/");         resolver.setsuffix(".jsp");         resolver.setviewclass(jstlview.class);         return resolver;     } } 

webinitializer.java

 package com.dnn.web.config;       //imports         public class webinitializer implements webapplicationinitializer {          public void onstartup(servletcontext servletcontext)                 throws servletexception {              annotationconfigwebapplicationcontext ctx = new annotationconfigwebapplicationcontext();             ctx.register(config.class);              ctx.setservletcontext(servletcontext);              dynamic servlet = servletcontext.addservlet("dispatcher", new dispatcherservlet(ctx));             servlet.addmapping("/");             servlet.setloadonstartup(1);                 }             } 

helloworldcontroller.java

package com.dnn.spring.controller; //imports @controller public class helloworldcontroller {     @requestmapping("/hello")     public string hello( @requestparam(value = "name", required = false, defaultvalue = "world") string name,   model model) {         model.addattribute("name", name);         return "helloworld";     } } 

when invoke application see following result:

localhost:8080/dnn-project/hello

returns same result.

i don't understand made mistake.

p.s. source code of example: source

i suppose spring doesn't see config , webinitializer classes don't understand why , how fix it.

p.s.

p.s.3

if send request url

http://localhost:8080/hello 

then

 мар 22, 2014 1:44:33 pm org.apache.catalina.core.standardwrappervalve invoke severe: servlet.service() servlet [dispatcher] in context path [] threw exception [handler processing failed; nested exception java.lang.noclassdeffounderror: javax/servlet/jsp/jstl/core/config] root cause java.lang.noclassdeffounderror: javax/servlet/jsp/jstl/core/config     @ org.springframework.web.servlet.support.jstlutils.exposelocalizationcontext(jstlutils.java:101)     @ org.springframework.web.servlet.view.jstlview.exposehelpers(jstlview.java:135)  ... 

there fine spring configuration. there part missing jstl dependency:

<dependency>     <groupid>javax.servlet</groupid>     <artifactid>jstl</artifactid>     <version>1.2</version> </dependency> 

tomcat not include jstl has shipped application.
