este dae é o erro…

vou colocar as listagens abaixo:

struts-config.xml:

[code]<?xml version="1.0" encoding="ISO-8859-1" ?>

<action 
	path="/Principal"
	forward="/pages/principal.jsp" >
</action>
	
<action 
	path="/Login" 
  	type="LoginAction"
  	name="loginAction"
  	scope="request"
  	input="/welcome.jsp">
	<forward name="sucesso" path="/Principal" redirect="true" />
</action>

[/code]

welcome.jsp:

[code]<%@ taglib uri="/WEB-INF/struts-html" prefix=“html” %>
<%@ taglib uri="/WEB-INF/struts-bean" prefix=“bean” %>
<%@ taglib uri="/WEB-INF/struts-logic" prefix=“logic” %>
<%@ taglib uri="/WEB-INF/struts-nested" prefix=“nested” %>

html:html

MCTI - Login

Usuário
Senha

[/code]

o Action do login:

[code]import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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 {
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
LoginForm login = (LoginForm )form;

	String username = login.getUsername();
	String passwd = login.getPasswd();
	
	/*if ("admin".equalsIgnoreCase(username) && 
	"admin".equalsIgnoreCase(passwd) ) {
		
	} */	
	return mapping.findForward("sucesso");
}

}[/code]

e o actionForm do login:

[code]import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;

public class LoginForm extends ActionForm {
private String username;
private String passwd;

// gets and sets
public String getPasswd() {
	return passwd;
}
public void setPasswd(String passwd) {
	this.passwd = passwd;
}
public String getUsername() {
	return username;
}
public void setUsername(String username) {
	this.username = username;
}

public void reset(ActionMapping mapping, HttpServletRequest req) {
	this.passwd = null;
	this.username = null;
}

public ActionErrors validate (ActionMapping mapping, HttpServletRequest req) {
	ActionErrors errors = new ActionErrors();
	
	if (username == null || passwd == null) {
		errors.add("errUsuarioSenha", new ActionError("UsuarioSenha.required"));
	}
	
	return errors;
}

}
[/code]

Eu não sei se isso corrigi o erro

Mas o correto seria assim

tem uma barra no inicio.

furutani,

coloquei a barra mas mesmo assim continua dando o mesmo erro…

com barra ou sem barra dá a mesma exception

henriqueor · Janeiro 30, 2007, 1:48pm

o meu action-mappings está correto??

digaoalves · Janeiro 30, 2007, 2:03pm

Tente fazer assim no seu mapeamento de Action:

<action path="/Login" type="LoginAction" name="loginForm" scope="request" input="/welcome.jsp">
