Struts Date Validation

Asked by: sunray_2003

HI,
I am having a problem in Struts Date Validation. My question , how to validate date fields in Struts

This is my form bean
        <form-bean name="orderForm" type="org.apache.struts.validator.DynaValidatorForm">
                      <form-property name="dateStart" type="java.util.Date" initial=""></form-property>
                      <form-property name="notes" type="java.lang.String" initial=""></form-property>                                                  
             </form-bean>                    
       
and my validator .xml is like
           <form name="orderForm" >
               <field property="dateStart" depends="required,date">
                   <arg0 key="certDetails.add.field.startDate"/>
                <var>
                    <var-name>datePattern</var-name>
                    <var-value>MM/dd/yyyy</var-value>
                </var>                  
               </field>              
           </form>

I keep getting this error
2005-10-28 03:36:41 StandardWrapperValve[action]: Servlet.service() for servlet action threw exception
org.apache.commons.beanutils.ConversionException: Cannot assign value of type 'java.lang.String' to property 'dateStart' of type 'java.util.Date'

1./change <form-property name="dateStart" type="java.util.Date" initial=""></form-property>
to <form-property name="dateStart" type="java.util.Date" ></form-property>

2./Comparing dates can be done like this http://www.javaalmanac.com/egs/java.util/CompDates.html

>>Cannot assign value of type 'java.lang.String' to property 'dateStart' of type 'java.util.Date'

     This is because by default there is no converter for java.util.Date ONLY for java.sql.Date. So no conversion will be used for your "" to proper java.util.Date value. So you could :
     (1) do as bloodredsun mentioned, no initial
or  (2) write your own convertor for java.util.Date
or  (3) use java.sql.Date instead but you have to use value as "2001-12-12" (default format) to initiate it.
