who's can help me with struts2 and hibernate to solve a particular exception: HTTP 404 - There is no Action mapped for namespace

I'm learning how to use struts2 and hibernate, but i can´t resolve this exception "There is no Action mapped for namespace [/] and action name [registrar_barrios] associated with context path [/ConsultarPatente].". I know it's asked many time, but it's common for several case, as well here we go:

The next is built on eclipse.

1.- Project explorer https://www.dropbox.com/s/4gg52h64e4hz64s/package.png?dl=0

2.- Codes (src and WebContent folers). https://www.dropbox.com/s/x3q9qtq050a8anv/Files.rar?dl=0

3.- I thinks AgregarBarrioAction and registrar_barrios are not working.

4.- Database.

CREATE TABLE `barrio_table` (
  `barrioId` int(11) NOT NULL auto_increment,
  `Nombre` varchar(24) collate utf8_bin NOT NULL,
  PRIMARY KEY  (`barrioId`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=4 ;

        barrioDAO.saveBarrio(barrio);
        return SUCCESS;
    }

    @Action
    (
        value="consultarBarrio",
        results={@Result(location="/registrar_barrios.jsp")}
    )
    public String list()
    {
        setBarrioList(barrioDAO.listBarrio());
        return SUCCESS;

    public void setBarrio(Barrio barrio)

    public void setBarrioList(List<Barrio> barrioList)

Give me a help, i appreciate to you. Good luck!!!

Solution

  • The error

    There is no Action mapped for namespace [/] and action name [registrar_barrios] associated with context path [/ConsultarPatente].

    is telling you that your action is not accessible. And it is not a surprise, since you don't have any @Action(name="registrar_barrios").

    Your actions are instead agregarBarrio and consultarBarrio:

    @Action(value="agregarBarrio", 
    results={@Result(location="/registrar_barrios.jsp", type="redirect")}   
)


@Action(value="consultarBarrio",
    results={@Result(location="/registrar_barrios.jsp")}
)

    The first result is also using redirect out of turn. Remove it.
