Hi
I have to make a check for the Date in a certain format(dd/MM/yyyy) on the JSP form. I am using struts framework for validation.
The problem is although i have used the validation function "date" for the date field of the form bean but still on submitt the validator is not checking for right input i.e. in the format in which i want: dd/MM/yyyy

the code for "Validation.xml" is:
<form-validation>
<formset>
<form name="/AddUpdateEmployee">
// "AddUpdateEmployee" is the name of the action mapping in Struts-config.xml
...
...
<field
property="empJoinDate"
depends="required,date">
<arg0
key="errors.date" resource="true"/>
<var>
<var-name>datePattern</var-name>
<var-value>dd/MM/yyyy</var-value>
</var>

</field>

and the code for validator-rules.xml is:
<validator name="date"
classname="org.apache.struts.util.StrutsValidator"
method="validateDate"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest"
depends="required"
msg="errors.date"
jsFunctionName="DateValidations">
<javascript>

Just to be sure: Did you configure your action-mapping in struts-config.xml to use the validation with validate="true"?

Does the "required" validation work?

Oh, and it might be a good idea to use datePatternStrict.

hey i got the error....
actually there was a mismatch of "datePattern" and "datePatternStrict" in validation.xml and validator-rules.xml...
in validation.xml i used "datePattern" and in validator-rules.xml i used "datePatternStrict"...
now it is prompting for the correct pattern of date...
thx guys
