validating user entered values
in strutsconfig.xml the form bean attribute has
<form-property name="newBalance" type="java.lang.String"/>
Prepare jsp action
Form1.set("newBalance", "100000");
In jsp I have
<fmt:formatNumber value="${Form1.map.newBalance}" type="currency"
currencySymbol="" var="newBal"/>
<html:text name="Form1" property="newBalance" value="${newBal}" />
Validator.xml has
<field property="newBalance" depends="double">
<msg name="double" key="notvalid"/>
</field>
The Dispatch action has
DynaValidatorForm frm = (DynaValidatorForm)form;
ActionMessages messages = (ActionMessages)frm.validate( mapping,
request );
when I try to submit the page/jsp getting Exception
javax.servlet.ServletException: javax.servlet.jsp.JspException: In
<formatNumber>, value attribute can not be parsed into
java.lang.Number: "100,000.00"
I understand that the String is entered i.e formbean has String value but
validating if it's double value.
How to handle such data? user entering in String but have to validate if
it's double?
Thanks.

The problem seems to be that your using NumberFormat to try and format
a property thats a String (rather than a Number). Its not even getting
to do any sort of validation - just blowing up trying to display your
page.
If your form property is a String then you need to handle the
formatting before you populate the value to your form.
