Exception: Cannot resolve reference to bean

Hello,

first of all, sorry about my english

I have create two *.jsp files.
In the first .jsp file (index.jsp) you can enter your name.

HTML Code:

...

<html>
	<head>
		<title>index.jsp</title>
	</head>
	<body>
		<form action="/spring/index.html" method="POST">
			insert your name<br />
			<input type="text" name="username"></input>
			<input type="submit" value="send" />
		</form>
	</body>
</html>

The second .jsp file (output.jsp) should display the entered name.

HTML Code:

...

<html>
	<head>
		<title>title</title>
	</head>
	<body>
		Hello <c:out value="${Person.name}"></c:out> !
	</body>
</html>

After pressing the submit button, i get the following error message.

org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name '/index.html' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: Cannot resolve reference to bean 'person' while setting bean property 'person'; nested exception is org.springframework.beans.factory.NoSuchBeanDefini tionException: No bean named 'person' is defined

spring-servlet.xml

Code:

...       
	<bean name="/index.html" class="org.spring.FrontController" >	
		<property name="formView" value="index" />
		<property name="successView" value="output" />

		<property name="person" ref="person" />

	</bean>
	
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/jsp/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>
...

FrontController.java

Code:

package org.spring;

import javax.servlet.ServletException;
import javax.servlet.h..p.H..pServletRequest;
import javax.servlet.h..p.H..pServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;

public class FrontController extends SimpleFormController {
	
	public FrontController() {		
		setCommandClass(PersonBean.class);
		setCommandName("person");
	}
	
	protected Object formBackingObject(HttpServletRequest request) throws ServletException {
		Object formBackingObject = null;
		try {
			formBackingObject = super.formBackingObject(request);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return formBackingObject;
	}
	
	protected Object referenceData(HttpServletResponse response) throws ServletException {
		return logger;		
	}

	protected ModelAndView onSubmit(Object command, BindException bindException) throws Exception {
		
		PersonBean person = (PersonBean) command;
		System.out.println("username: " + person.getUsername());
		
		// return new ModelAndView("output", "person", person);
		System.out.println("view: " + getSuccessView());		

		return new ModelAndView(getSuccessView());		
	}

}

PersonBean.java

Code:

package org.spring;

public class PersonBean {
	
	private String username;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}	
}

How can i fix the bug ?

Thanks
Angelika

remove the following from your spring configuration

Code:

<property name="person" ref="person" />

the xml should look like the following

Code:

<bean name="/index.html" class="org.spring.FrontController" >	
		<property name="formView" value="index" />
		<property name="successView" value="output" />


	</bean>
