problem with spring-sandbox Validation

[h]

I try this code to validate my form:

--validation.xml--
<form-validation>
<formset>
<form name="smsForm">
<field property="text" depends="required">
<arg0 key="smsForm.text"/>
</field>
</form>
</formset>
</form-validation>

--sms.jsp--<form name="smsForm" method="post" action="<c:url value="/sendsms.form" />">
<table width="75%" border="0">
<tr>
<td></td>
</tr>
<tr>
<td><fmt:message key="smsform.msisdn"/>
<spring:bind path="command.instances">
<input type="text" name="${status.expression}" value="${status.value}">
<FONT color="red">
<B>${status.errorMessage}</B>
</FONT>
</spring:bind>
</td>
</tr>
<tr>
<td><fmt:message key="smsform.text"/>
<spring:bind path="command.text">
<textarea name="${status.expression}">${status.value}</textarea>
<FONT color="red">
<B>${status.errorMessage}</B>
</FONT>
</spring:bind>
</td>
</tr>
<tr>
<td><input type="submit" name="Submit" value="Submit"></td>
</tr>
</table>
</form>

--spring-servlet.xml--<bean id="SendSmsController" class="com.web.SendSmsController">
<property name="validator">
<ref bean="beanValidator"/>
</property>
</bean>

--appicationContext.xml--
<bean id="validatorFactory" class="org.springframework.validation.commons.Vali datorFactory"
init-method="init">
<property name="resources">
<list>
<value>/WEB-INF/validator-rules.xml</value>
<value>/WEB-INF/validation.xml</value>
</list>
</property>
</bean>

<bean id="beanValidator" class="org.springframework.validation.commons.Bean Validator">
<property name="validatorFactory"><ref local="validatorFactory"/></property>
</bean>



So when i deploy the application i have error message :( :

java.lang.IllegalArgumentException: Validator [org.springframework.validation.commons.BeanValidat or@b0f0ae] does not support command class [com.model.Sms]

:?: :?: what is the problem????????

Change this tag:

<form name="smsForm">

to:

 <form name="sms">

Spring's support for Commons Validator uses the class name for the form name.

I am kinda wondering if there is any other way to define validations, for example, if you have more than one set of validations for a particular object. In Struts, you don't have this limitation.

:D
think you!
work successfully!

now i try to validate whith a regular expression,it's work with javascript validation, but the server validation don't work!

my code is:

<form name="sms">
<.......>		
			<field property="instances" depends="required,mask">
		        <msg name="mask" key="errors.maskmsg" />
				<arg0 key="smsform.instances" />
		        <var>
					<var-name>mask</var-name>
					<var-value>&#91;0-9&#93;+</var-value>
				</var>
		    </field>
			
        </form>

i try a simple regular expression, so only "required" validation work on the server!
"mask" validation have no effect on the server

There is a way to do this. Unfortunately, the documentation sucks (I wrote it, I can say that :lol: ). Look at NamedBeanValidator. You can simply configure a different one for each set of validation rules you want to use:

springContext.xml

<bean id="smsValidator1" class="org.springframework.validation.commons.NamedBeanValidator">
  <property name="validatorFactory"><ref local="validatorFactory"/></property>
  <property name="beanName"><value>sms1</value></property>
</bean>

<bean id="smsValidator2" class="org.springframework.validation.commons.NamedBeanValidator">
  <property name="validatorFactory"><ref local="validatorFactory"/></property>
  <property name="beanName"><value>sms2</value></property>
</bean>

validation.xml

<form name="sms1">
  ...
</form>

<form name="sms2">
  ...
</form>

dmiller - thanks, that is what I'm looking for... So the NamedBeanValidator, when used with the Validator interface, will always try to validate any object given to it using the validations specificied by its beanName property?

h - haven't tried regexp myself, will give it a try

[nilesh]

I read in the Struts Validator documentation that you need to begin your mask with ^ and end with $. So for example, I have a mask variable like this which works:

    <var><var-name>mask</var-name><var-value>^&#91;-.-9A-Za-z&#93;*$</var-value></var>

think you nilesh, i anderstand the problem and i have the solution
so , now, i wnat to validate in client by a regular expression and in the server by an other regular expression ,
because in client i have a string like
"22222,33333,22222"
i must validate with this reg exp:
^[0-9]+(( *|,) *[0-9]+)*$
in hte server part i have a property editor whitch parse a String and make a Set .
i must validate evry Instance on this set.
i try this code:
--validation.xml--

field property="instances" depends="required,maskList">
				<msg name="maskList" key="errors.maskListmsg"/>
				<arg0 key="smsform.instances" />
		        <var>
					<var-name>maskList</var-name>
					<var-value>^&#91;0-9&#93;+$</var-value>
				</var>
				
				<var>
					<var-name>mask</var-name>
					<var-value^&#91;0-9&#93;+&#40;&#40; *|,&#41; *&#91;0-9&#93;+&#41;*$</var-value>
				</var>
				<var>
					<var-name>champ</var-name>
					<var-value>destination</var-value>
				</var>
				
            </field>

--validator-rules.xml--

<validator name="maskList"
            classname="com.validation.ListFieldChecks"

--com.validation.ListFieldChecks.java--

public static boolean validateMaskList(Object bean, ValidatorAction va, Field field, Errors errors){
	 	
		String champ = field.getVarValue("champ");
		
		
		Object liste=null;
		
		try {
			liste = PropertyUtils.getProperty(bean,field.getProperty());
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block

	 	Field f1=new Field();
	 	f1.setProperty(champ);
	 	f1.addArg(field.getArg(0));
	 	Var maskList = field.getVar("maskList");
	 	maskList.setName("mask");
	 	f1.addVar(maskList);
	 	Msg msg= new Msg();
	 	msg.setName("maskList");
	 	msg.setKey(field.getKey());

	 	for (Iterator iter = set.iterator(); iter.hasNext();) {
	 		
			Object element = (Object) iter.next();
			if(!FieldChecks.validateMask( element,  va,  f1,  errors)){
								return false;
			}
		}
	 		return true;
	}

now i have a propblem whit initializing the Field.

That's correct.
