Hi all,
I really need a big help in validation with Struts, I dont know why but
I just cant validate a very simple form I have, with 2 simple fields
(login and password), I have follown all tutorials I got but til now no
success.
I am not able to validate either in server side or client side.
I am using Struts 1.2.7 - Is there any big difference in validating with
this version and the previous ones?
Here are the stpeds I did:
1) created the DynaValidatorForm in struts-config and mapped the Actions
it there too.
//-------------------------------------------------------------------------------------
....
<form-beans>
<form-bean name="loginForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="login" type="java.lang.String" />
<form-property name="senha" type="java.lang.String" />
<form-property name="senha2" type="java.lang.String" />
</form-bean>
</form-beans>
....
<!-- this one is called to show the page with the fields -->
<action path="/prepararLogin"
type="br.com.gerente.SuccessAction">
<forward name="success" path="/paginas/login.jsp"/>
</action>
<!-- this one is processed when the submit button is pressed -->
<action path="/Login"
type="br.com.gerente.ProcessaLoginDynaAction"
name="loginForm"
scope="request"
input="input"
validate="true">
<forward name="success" path="/paginas/clienteCadastro.jsp"/>
<forward name="input" path="/prepararLogin.do" />
</action>
...
<message-resources parameter="br/com/gerente/Resources"/> ...
<!-- ========================= Validator plugin
================================= -->
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property
property="pathnames"
value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/>
<set-property property="stopOnFirstError" value="true" />
</plug-in>
2) create the action to call the login.jsp (and others): SuccessAction.java
//-------------------------------------------------------------------------------------
package br.com.gerente;
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 SuccessAction extends Action {
/** Creates a new instance of SuccessAction */
public SuccessAction() {
super();
}
/**
* Returns the <code>ActionForward</code> named "success" if one is
* configured or <code>null</code>if it cannot be found.
*
* Searches first for a local forward, then a global forward.
*
* @param mapping The ActionMapping used to select this instance
* @param form The optional ActionForm bean for this request (if any)
* @param request The HTTP request we are processing
* @param response The HTTP response we are creating
*
* @exception Exception if mapping.findForward throws an Exception
*
* @return the "success" ActionForward, or null if it cannot be found
*/
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
return mapping.findForward("success");
}
}
3) created the action: ProcessaLoginDynaAction.java
package br.com.gerente;
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;
import org.apache.struts.validator.DynaValidatorForm;
public class ProcessaLoginDynaAction extends Action {
/** Creates a new instance of ProcessaLoginDynaAction */
public ProcessaLoginDynaAction() {
super();
}
/**
* Process the request and return an <code>ActionForward</code> instance
* describing where and how control should be forwarded, or
* <code>null</code>if the response has already been completed.
*
* @param mapping The ActionMapping used to select this instance
* @param form The optional ActionForm bean for this request (if any)
* @param request The HTTP request we are processing
* @param response The HTTP response we are creating
*
* @exception Exception if the application logic throws an exception
*
* @return the ActionForward for the next view
*/
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
// Se o usuario pressionar o botao 'Cancelar' volta para o
inicio
if (isCancelled(request)) {
return mapping.findForward("inicio");
}
DynaValidatorForm dynaForm = (DynaValidatorForm)form;
//dynaForm.set("login","nome do login");
//System.out.println("Login: "+dynaForm.get("login") );
// Forward to result page
return mapping.findForward("success");
} }
4) created login.jsp:
//-------------------------------------------------------------------------------------
<%@ taglib uri="http://jakarta.apache.org/struts/tags-bean";
prefix="bean" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-html";
prefix="html" %>
<%@ taglib uri="http://jakarta.apache.org/struts/tags-logic";
prefix="logic" %>
<html:html locale="true">
<head>
<title><bean:message key="login.titulo"/></title>
<html:base/>
<link rel="stylesheet" type="text/css" href="estilo.css" />
</head>
<body>
<center>
<h1><bean:message key="login.titulo"/></h1>
<html:errors property="login"/>
<table border="0" width="50%">
<html:form action="/Login.do" focus="login" method="post"
onsubmit="return validateformLogin(this)">
<thead>
<tr>
<th></th>
<th></th>
</tr>
</thead>
<tbody>
<tr>
<td class="into"><bean:message
key="login.nome"/></td>
<td>
<html:text property="login" size="20"
maxlength="20" />
</td>
</tr>
<tr>
<td><bean:message key="login.senha"/></td>
<td><html:password property="senha" size="20"
maxlength="10"/></td>
</tr>
<tr>
<td></td>
<td>
<html:submit>
<bean:message key="botao.enviar" />
</html:submit>
<html:cancel>
<bean:message key="botao.cancelar" />
</html:cancel>
</td>
</tr>
</tbody>
</html:form>
</table> </center> </body>
<html:javascript formName="loginForm" dynamicJavascript="true"
staticJavascript="false"/>
</html:html>
5) The resources file: Resources.properties
//-------------------------------------------------------------------------------------

6) the validation.xml:
//-------------------------------------------------------------------------------------
<formset language="pt" country="BR" >
<constant>
<constant-name>postalCode</constant-name>
<constant-value>^[0-9a-zA-Z]*$</constant-value>
</constant>
<form name="loginForm">
<field property="login" depends="required">
<arg key="login.nome"/>
</field>
<field property="senha" depends="required">
<arg key="login.senha"/>
</field>
</form>
</formset>
//-------------------------------------------------------------------------------------
So, according to the mapping action when I press the submit button with
the fileds empty it should show me 2 messages in the page, right? But it
does not show anything, just call the next page.
What am I doing wrong?
I really would appreciate any help from you guys.
Thanks in advance.
Francisco.
