I made a model from a controller and return to dispatcherservlet. It looks like there is no problem
in model since I double checked output by system.out.println. for viewname string, I double checked
an actual directory name which is “WEB-INF/views/hello.jsp”.
but I believe dispatcher servlet does not adapt model to a view since browser does not displayed
a model value which should be displayed. It would be easier to understand what I am going through
if I put my code here. so… here is my code.
web.xml
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/spring/appServlet/spring-servlet.xml
</param-value>
</context-param>
spring-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>

<context:annotation-config/>
<bean name="/hello" class="com.spring.toby.HelloController"/>
<bean id="HelloSpring" class="com.spring.toby.HelloSpring"></bean>
</beans>
and controller java file
public class HelloController implements Controller{
@Autowired HelloSpring helloSpring;
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
// TODO Auto-generated method stub
String name = request.getParameter("name");
String msg = this.helloSpring.sayHello(name);
System.out.println(msg);
Map<String, Object> model = new HashMap<String, Object>();
model.put("msg", msg);
return new ModelAndView("WEB-INF/views/hello.jsp", model);
}
}
and bean file
public class HelloSpring {
public String sayHello(String name){
return "Hello " + name;
}
}
and jsp file
</head>
<body>
<div><h1>Testing</h1></div>
${message}
</body>
can anybody tell me what am I doing wrong? thanks in advance.
Its just a silly mistake.
Please replace ${message} in your jsp with ${msg} and you will get the message printed in your jsp.
Hope this helps you.
Cheers.
