esse eh meu bean

package br.com.seguradora.form;

public class loginForm {

	private String usuario;
	private String senha;

	public String getUsuario() {
		return usuario;
	}

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

	public String getSenha() {
		return senha;
	}

	public void setSenha(String senha) {
		this.senha = senha;
	}

}

esse é meu action

package br.com.seguradora.action;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class loginAction extends Action {
	
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm action,
			ServletRequest request, ServletResponse response) throws Exception {

		return mapping.findForward("valid");
	}
	
}

essa aqui eh meu strut-config.xml

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC

	    <forward name="valid" path="/index.jsp" />
	</action>
  </action-mappings>

</struts-config

aqui está meu web.xml

igson_mendes_da_silv 14 de mar. de 2008

Se postar o codigo fica melhor

igson_mendes_da_silv 14 de mar. de 2008

Você tem que mapear na Action o ActionForm que ela vai utilizar .

igson_mendes_da_silv 14 de mar. de 2008

Da uma olhada no site do Struts la tem um exemplo pq neste momento nao estou com o exemplo aki

igson_mendes_da_silv 17 de mar. de 2008

<form-beans>
    	 <form-bean name="login" type="pkg.form"/>
</form-beans>

<action  path="/ExibirLogin" type="pacote_onde_esta_sua_action" name="login(nome do fom-bean identificado aí em cima)" scope="request" validate="false" >
</action>

espero que ajude
