Dynamic Validation

[Navi Lock]

Friends, need some help on the below..

Idea is to learn Dynamic validation using Struts Validation framework.
I am using "org.apache.struts.validator.DynaValidatorForm" for validating a form as below :

Struts-Config.xml:-
<form-beans>
<form-bean name="dummy" type="org.apache.struts.validator.DynaValidatorActionForm">
<
form-property name="tn" type="java.lang.String" />
</form-beans>
<action path="/myController" type="abc.efg.controller" name="dummy" validate="true" scope="request">
<forward name="RESULT_PAGE" path="/Response.jsp" />
<forward name="TECH_DIFFICULTY" path="/TechDifficulty.jsp" /> <forward name="VALIDATION_FAILURE" path="/Request.jsp" /> </action>

Validation.xml:-
<form-validation> <formset> <form name="dummy"> <field property="tn" depends="required"> <arg0 key="prompt.TN" /> </field> </form> </formset> </form-validation>

Request.jsp page :-

<html:errors/> <html:form action="myController"> <TABLE border="1"> <TBODY> <TR> <TD width="364">Form</TD> </TR> </TBODY> </TABLE> <TABLE border="10"> <TBODY> <TR> <TD> Telephone Number</TD> <TD width="184"><INPUT name=<%=SimpleConstants.TN %> type="text" value="" size="21"></TD> </TR> </TBODY> </TABLE> .. ..

I am not entering any value for TN field. My understanding is that, if you use Dynamic Forms then the flow should not reach the Action (myController) ..
but it does and does not throw any validation exceptions on the page..

Please let me know what i am missing..

Thanks in advance -Navi

Are you? Your code snippet is using DynaValidatorActionForm. The "action" versions of these forms differ in that they look for a validator rule where the name matches the name of action. Try switching over to use DynaValidatorForm and see if that fixes your problem.

Hi Brent,
Thanks for responding..
Yes i am using 'DynaValidatorActionForm'..apologies for the wrong info..

But if i try using the 'DynaValidatorForm' i get the follwoing message
'No input attribute for mapping path /myController'


I am open to either one.. just dont want to create Static forms if possible...

Also i changed the Validation.XMl file as below ('DynaValidatorActionForm') but no changes

<form name="myController">
<field property="tn" depends="required">
<arg0 key="prompt.TN" />
</field>
</form>


Thanks,
-Navi.

My apologies..
I had named the validation.xml file as 'Validation.xml'{upper case} and that was causing to miss the validation.

Thanks again for the responses
