Struts Validator Framework Error ...Depends String is not Found in validator-rules.

[Rahul Nair]

Hi,

I am using struts validation framework for validating my fields....I use custom validation class to validation my fields for Number...
when i try to run application it shows following error...

" java.lang.NullPointerException: Depends string "cNumber" was not found in validator-rules.xml. "

my validation file entry is...

<field property="phoneNumber"
depends="cNumber">
<arg key="form.Number"/>
</field>

and validation rules.xml entry is ...

<validator name="cNumber"
classname="com.myApp.ContactNumberValidator"
method="validateContactNumber"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
depends=""
msg="errors.contactNumber"/>


I am not getting what is wrong with my code....

Please help me ?

Thanks

It seems OK to me. Just make sure that you are using this validation rules file and that you set its location correctly in the validation plugin definition. I know that it's elementary, but I sometimes do much more stupid things

Thanks Alaa,

But if i remove above validation rule then the rest form filed validation is working fine through same validation files in my application....

And It is says Depends string not found in Validation-rules.xml file.....

I Had correctly mapped the validation rule cNumber in my validation file...

Please help if someone knows about this...

Thanks

hey,

you might want to remove the depends tag in the validator-rules.xml file.
It should ideally look like

<validator name="cNumber"
classname="com.myApp.ContactNumberValidator"
method="validateContactNumber"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
org.apache.commons.validator.Validator,
javax.servlet.http.HttpServletRequest"
msg="errors.contactNumber"/>

try and see if this works.

Thanks,
