500 Action does not contain method named

Question

I’m making an action call but I get Exception that the method doesn’t exist in Action:

500 Action[/historicoAction] does not contain method named listar

Would anyone know what’s going on?

Follows files:

struts-config

<form-bean name="historicoForm" type="br.com.liquigas.portal.form.HistoricoForm"/>

<forward name="/historicoAction" path="/historicoAction.do"></forward>

<action path="/historicoAction" type="br.com.liquigas.portal.action.HistoricoAction" name="historicoForm" scope="request" parameter="method">
    <forward name="success" path="/jsp/historico/historicoPedido.jsp"></forward>
    <forward name="failure" path="/jsp/historico/erro.jsp"></forward>
    <forward name="historicoPedido" path="/jsp/historico/historicoPedido.jsp"></forward>
    <forward name="historicoProduto" path="/jsp/historico/historicoProduto.jsp"></forward>
</action>

ACTION

public ActionForward listar(ActionMapping mapping, ActionForm form, 
        HttpServletRequest request, HttpServletResponse response) throws Exception {
    ...
} 

Answer 1

Guys, I managed to solve my problem with a simple change in the parameters of the Actionforward method. The problem was the method:

public Actionforward detail(Actionmapping Mapping, Actionform form, Httpactionrequest request, Actionresponse Response) throws Exception { }

I also tried with the: public Actionforward detail(Actionmapping Mapping, Actionform form, Httprequest request, Actionresponse Response) throws Exception { }

and it didn’t work....

Corrected with the

public Actionforward detail(Actionmapping Mapping, Actionform form, Actionrequest request, Actionresponse Response) throws Exception { }
