pb with beans declaration (newbi)

[Dadooo]

hi every one I m just dong a little sample to learn more about Spring, I made something quite close to the MVC sample, but I have a error with me beans declaration and I really can't find out the trouble. When I lunch tomcat on it I get :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'artistsController' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Can't resolve reference to bean 'art' while setting property 'artistsController'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'art' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Can't resolve reference to bean 'art1' while setting property 'artists[0]'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'art1' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'nom' of bean class [bus.Artist]: Bean property 'nom' is not writable or has an invalid setter method: Does the parameter type of the setter match the return type of the getter?

in my springapp-servlet

   
...
 <bean id="artistsController" class="web.ArtistsController">
        <property name="artistsController">
            <ref local="art"/>
        </property>
    </bean>   
...

   <bean id="art" class="bus.ArtistManager">
        <property name="artists">
            <list>
                <ref bean="art1"/>
                <ref bean="art2"/>
...

they refer to simple class :
the controller

[CODE]package web;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Map;
import java.util.HashMap;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import artists.Product;
import artists.ProductManager;


public class SpringappController implements Controller {
/** Logger for this class and subclasses */
private ProductManager prodMa;
protected final Log logger = LogFactory.getLog(getClass());
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response){
try {
String now = (new java.util.Date()).toString();
logger.info("returning hello view with " + now);

Map myModel = new HashMap();
myModel.put("now", now);
myModel.put("products", getProductManager().getProducts());

return new ModelAndView("main", "model", myModel);}
catch (ServletException e){}
catch (IOException e) {}
}

public void setProductManager(ProductManager pm) {
prodMa = pm;
}

public ProductManager getProductManager() {
return prodMa;
}
}
[CODE]

artistManager

package artists;
import java.io.Serializable;
import java.util.List;
public class ArtistManager implements Serializable {
    private List artists;
    public void setArtists(List a) {
        artists = a;
    }
    public List getArtists() {
         return artists;
    }
}

and artists

package artists;
import java.io.Serializable;
public class Artists implements Serializable {
    private String name
    private String genre
    private String description
    }
    
    public void setName(String n) {
        name = n;
    }
    public String getName() {
        return name;      
    }    
    public void setGenre(String g) {
        genre = g;
    }
    public Double getGenre() {
        return genre;
    }
    
    public void setDescription(String d) {
        description = d;
    }
    public String getDescription() {
        return description;    
    
}

It's maybe quite nothing but I spend hours on it, I really apreciate I somebody can Help. thanks Bye

As the exception states; you are trying to call "setNom" on the Artist class, but there is no such setter

[Dadooo]

Thak you very much I was focusing on something else

No worries.

In general, Spring exceptions are very information and tend to explain exactly what the problem is.
