hi I am going through my first lessons with spring 3.I created a dynamic web app in eclipse with the following structure.
spring3mvc \src\my.spring.HelloWorldController.java
\WebContent
|
|-----WEB-INF\jsp\hello.jsp
|-----index.jsp
|-----web.xml
|-----WEB-INF\spring-servlet.xml
|-----WEB-INF\lib\...*.jar files
I created the spring-servlet.xml as below
<context:component-scan base-package="my.spring" />
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
and coded the controller
package my.spring;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloWorldController {
@RequestMapping("/hello")
public ModelAndView helloWorld() {
String message = "Hello World, Spring 3.0!";
return new ModelAndView("hello", "message", message);
}
}
index.jsp has a link to hello view
<html>
<body>
<a href="hello.html">Say Hello</a>
</body>
</html>
finally in hello.jsp I have put
<html>
<body>
${message}
</body>
</html>
My web.xml has
<display-name>Spring3MVC</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
When I run the app on Tomcat6 server( thru eclipse),I can see the index page at http://localhost:8080/Spring3MVC/ .It displays the link to hello page.When I click on it(http://localhost:8080/Spring3MVC/hello.html),I get a 404 error.
message /Spring3MVC/hello.html
description The requested resource (/Spring3MVC/hello.html) is not available.
Any idea how I can solve this?
thanks
mark.
