Help - I cannot validate a simple form with 2 fields
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
//-------------------------------------------------------------------------------------
#--- erro padrao --

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.

Re: Testing Struts Applicaton

Sorry, I meant a distribution of the current sources rather than sources
for the last release. Try here:
http://svn.apache.org/builds/struts/maven/trunk/nightly/struts-taglib/
I don't know what's in the taglibs project will help you, but it does
use Cactus so it might at least get you started.

hi Laurie,
I am trying to test my struts appplication,
first I tried MockStrutsTestCase but its not working because
my database connections are coming via tomcat(I have placed my
jconnect.jar file in tomcat_home/common/lib and configured my
application's context.xml file)
Therefore I am looking to use In-Container Testing
That's the reason I was asking for some sample CactusStrutsTestCase code
I also downloaded Struts-src from
http://apache.mirrors.redwire.net/struts/source/struts-1.2.7-src.zip
but didn't get any taglibs/test-cactus in it

That's a bit vague; what are you trying to test? One place you could
look is the Cactus test suite for the taglibs subproject in the Struts
source (grab a current source distribution or checkout from subversion,
and look in taglibs/test-cactus).

Alright thanks, you know what? I am giving up Struts,,,,
I dont understand why this stuff has to be so complicated and nobody in
the whole world knows anything about it, I am Swing developer and I
think I will keep that.
Thanks anyway

Re: Help - I cannot validate a simple form with 2 fields
Posted by Laurie Harper <la...@holoweb.net>.
Erm, yes? You were complaining that validator wasn't being invoked after
you switched to sub-classing ActionForm directly / implementing
validate() yourself. I was just pointing out that it's not expected to
be in that case.

Re: Help - I cannot validate a simple form with 2 fields
Posted by Laurie Harper <la...@holoweb.net>.
If you are just using an ActionForm subclass you wrote, Validator isn't
used so the behaviour you're now seeing is correct. If you want to use
Validator, your ActionForm class needs to extend ValidatorForm or
ValidatorActionForm rather than ActionForm; if you want to include a
validate() method in that class, it should call super.validate() to
invoke the Validator-supplied validation.

Re: Help - I cannot validate a simple form with 2 fields
Posted by Francisco Antonio Vieira Souza <av...@yahoo.com.br>.
I really dont get it, I might be being so stupid not figuring out what
is going on wrong here, but I dont.
Clearing a little. I decided not to use DynaForm and go back to the
usual ActionForm and gave up using Client-side validation.
When I implement the validate method of the Bean (as it is now) I get
the error messages as expected, but I had to create a protected method
to check if the field was null or blank, then put the error message in
the ActionMessage.
But I dont see any sense in doing such thing like that, why should I do
this inside validate method if I have already said in validation.xml
that those fields are REQUIRED, at least that message should be shown to
the user. Correct me if I am wrong.
If I comment the validate method nothing happen, it is not able to check
if the field was left blank.
Please be pacience and have a look again:

Re: Help - I cannot validate a simple form with 2 fields
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
On the client side validation it looks like you have spelt the javascript
method name wrong in the form's onsubmit event. You can easily check the
client side by seeing what javascript has been generated for the page by
viewing the source.
For the sever side I can't see anything obviously wrong. Probably the best
approach would be to switch on "debug" level logging for the
RequestProcessor - it will tell you whats happening when it does the
processValidate() method.
The one thing I'm wondering is - do you have a "default" formset (i.e. one
with no language/country specified) in your validation.xml? In case it is
not using the pt_BR locale for some reason it would be a good idea to have a
default formset.
