Error using Struts Validator

[Marcos Gomes]

Hi guys,

I'm trying to use validator, but Tomcat throws the following exception:

18/04/2008 10:15:24 org.apache.struts.validator.ValidatorForm validate

SEVERE: No such validation method: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, javax.servlet.http.HttpServletRequest)

org.apache.commons.validator.ValidatorException: No such validation method: org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object, org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages, javax.servlet.http.HttpServletRequest)

at org.apache.commons.validator.ValidatorAction.loadValidationMethod(Val
idatorAction.java:604)

...


*************************************************
The file validator-rules.xml seems to be correct:
*************************************************

<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">

<form-validation>

<global>

<validator name="required"
classname="org.apache.struts.validator.FieldChecks"
method="validateRequired"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest"
msg="errors.required"/>

// other definitions

</global>

</form-validation>

*************************************************
And this is my validation.xml file:
*************************************************

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE form-validation PUBLIC
"-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1.3//EN"
"http://jakarta.apache.org/commons/dtds/validator_1_1_3.dtd">

<form-validation>
<formset>
<form name="ContactForm">
<field property="contact.company" depends="required">
<msg name="required" key="lilldep.error.company"/>
</field>
<field property="contact.name" depends="required">
<msg name="required" key="lilldep.error.name"/>
</field>
<field property="contact.email" depends="required">
<msg name="required" key="lilldep.error.email"/>
</field>
</form>
</formset>
</form-validation>

*************************************************

Please,

Somebody has already had this kind of problem and would help me to solve it ??

Thanks,

Marcos

This looks like a problem that might occur if you have jar files from one Struts version and TLDs from another. Make sure that all the artifacts you reference in your project come from the same Struts download.
