Problems with ModelAndView in AbstractCommandController

[carlos_santiago]

Hi, I'm with problems to show my view success in AbstractCommandController.
I insert any value in return new ModelAndView("any value"); and no errors occur and not show the correct view.
My code is:

    protected ModelAndView handle(HttpServletRequest request,  HttpServletResponse response, 
            Object obj,  BindException erros)  throws Exception {
        
        UsuarioBean bean = (UsuarioBean)obj;
        
        usuario.atualizaStatus(new Integer(DominioStatus.ATIVO), bean.getCodigoUsuario());

        return new ModelAndView("Success");
    }

But, any erros occur and no show my JSP !
Why ?
Thank's
Carlos

Can you post the rest of your MVC related configuration?

Hi Rob, thank's for its attention. He would like to say that I am reading its book Pro Spring and has been very good.
He follows my code all.
Not I understood because the ModelAndView is not redirecting for correct jsp. And nor because any inserted URL there not cause errors.

public class ExcluirUsuariosControlador extends AbstractCommandController{
    
    private Usuario usuario;
    
    public ExcluirUsuariosControlador(){
        this.setCommandClass(UsuarioBean.class);
    }
    
    protected ModelAndView handle(HttpServletRequest request,  HttpServletResponse response, 
            Object obj,  BindException erros)  throws Exception {
        
        UsuarioBean bean = (UsuarioBean)obj;
        
        usuario.atualizaStatus(new Integer(DominioStatus.INATIVO), bean.getCodigoUsuario());

        return new ModelAndView("Success");
    }


    public void setUsuario(Usuario usuario) {
        this.usuario = usuario;
    }

}

	<bean id="listaUsuariosControlador" class="br.com.rodobens.web.usuario.ListaUsuariosControlador" >
		<property name="sessionForm" value="true"/>
		<property name="commandName" value="usuario"/>
		<property name="commandClass" value="br.com.rodobens.beans.usuario.UsuarioBean"/>
		<!-- <property name="validator" ref="usuarioValidacao"/> -->
		<property name="formView" value="controleAcesso/ListaUsuarios"/>
		<property name="successView" value="controleAcesso/ListaUsuarios"/>
		<property name="usuario" ref="usuario"/>	
		<property name="grupo" ref="grupo"/>
	</bean>	
	<bean id="excluirUsuariosControlador" class="br.com.rodobens.web.usuario.ExcluirUsuariosControlador">
		<property name="usuario" ref="usuario"/>
	</bean>
        .
        .
        .
	 <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
		<property name="mappings">
			<props>
                <prop key="/controleAcesso/excluirUsuarios.lpw">excluirUsuariosControlador</prop>
                 <prop key="/controleAcesso/listaUsuarios.lpw">listaUsuarios</prop>
			</props>
		</property>
	</bean> 
        .
        .
        .
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"><value>org.springframework.web.servlet.view.JstlView</value></property> 
		<property name="prefix"><value>/WEB-INF/views/</value></property>
		<property name="suffix"><value>.jsp</value></property>
	</bean>

The Success.jsp, for example, is in /WEB-INF/views and any outhers controllers show it's view.
In the truth I would like that this my ModelAndView was for/acontroleacesso/listaUsuarios.lpw

Is the controller actually getting invoked? I can't see anything wrong with the code or configuration for your controller.

this line in your view resolver config:

<prop key="/controleAcesso/listaUsuarios.lpw">listaUsuarios</prop>

shouldn't it be like this?:

<prop key="/controleAcesso/listaUsuarios.lpw">listaUsuariosControlador</prop>

because that's the name you've given the controller bean

Shan, the problem is not this, therefore reverifiquei my file of context and it is same OK. Because if I had indicated one context missed I I would get one exception, what he does not happen.

Rob, my AbstractCommandController is invoked from of one jps that it was renderizing by a SimpleFormController.
I make submit with Javascript of this:

<SCRIPT>
function submitFunction&#40;valor&#41; &#123;
   if &#40;valor==1&#41;
   	document.forms&#91;0&#93;.action="statusUsuarios.lpw?parametro=excluir";
   
   if&#40;valor == 2&#41;
   	document.forms&#91;0&#93;.action="statusUsuarios.lpw?parametro=incluir";

   document.forms&#91;0&#93;.submit&#40;&#41;;
   &#125;
</SCRIPT>

The steps are:
first: it calls view SimpleFormController.
second: form is filled and envoy to the AbstractCommandController through submir of Javascript.
third: it enters in abstractFormController and the data correctly are processed.
4: view indicated in ModelAndView de AbstractCommandController does not go for any (or to quaquer another Controller), also with url's made a mistake and error does not occur some!
fifth: jsp is static in jsp of the SimpleFormController.
I am not it's happen !
Thank's

Carlos,
How do you have your servlet mapping setup?

<servlet-mapping>
        <servlet-name>SERVLETNAME</servlet-name>
        <url-pattern>*.LPW</url-pattern>
</servlet-mapping>

Steve O

[carlos_santiago]

Yes Steve may mapping is:

	<servlet-mapping>
    		<servlet-name>linkPecas</servlet-name>
    		<url-pattern>*.lpw</url-pattern>
  	</servlet-mapping>

[carlos_santiago]

Now I have this exception:

javax.servlet.ServletException: Invalid key [null] in model Map - only Strings allowed as model keys

And may ModelAndView is:

return new ModelAndView("Sucesso").addAllObjects(erros.getModel());

What's happen ?
Thank's
Carlos
