I have an arraylist object as commandclass -JoblessHistories which contains
jobhistory objects. When jsp loop through JoblessHistories, startDateMonth in jobhistory should be validated.

But my validation class seems does not work. Do you know any solutions?
I don't like convert my JoblessHistories into a normal commandclass, since there are dynamic member jobhistory objects will be displayed in jsp

My Bean
<bean id="editUnemploymentHistoryForm" class="com.ameriquest.ea.web.UnemploymentHistoryCo ntroller">
<property name="formView"><value>addUpdateUnemploymentHistor yForm</value></property>
<property name="commandClass"><value>com.ameriquest.ea.domai n.JoblessHistory</value></property>
<property name="successView"><value>unemploymentDataRedirect </value></property>
<property name="backView"><value>employmentDataBackRedirect</value></property>
<property name="validator"><ref local="unemploymentHistoryValidator"/></property>
</bean>

My jsp :
jobLessHistories is an arraylist which contains mutilple jobhistory objects,
In jobhistory object, there is an instance variable as startDateMonth. I want to validate to validate startDateMonth

<c:forEach varStatus="loop" items="${command.joblessHistories}">
<td valign="top" nowrap>
<spring:bind path="command.joblessHistories[${loop.index}].startDateMonth">
<FONT color="red">
<B><c:out value="${status.errorMessage}"/></B>
</FONT>
<INPUT type="text" maxlength="2" size="2" name="<c:out value="${status.expression}" />" value="<c:out value="${status.value}"/>" >
</spring:bind>
/
<spring:bind path="command.joblessHistories[${loop.index}].startDateYear">
<INPUT type="text" maxlength="4" size="4" name="<c:out value="${status.expression}" />" value="<c:out value="${status.value}"/>" >
</spring:bind>
</td>
</c:forEach>

My validator

public class UnemploymentHistoryValidator implements Validator {

public boolean supports(Class clazz) {
return JoblessHistory.class.isAssignableFrom(clazz);
}


public void validate(Object obj, Errors errors) {
JoblessHistory jb = (JoblessHistory) obj;

Iterator it = jb.getJoblessHistories().listIterator();
while ( it.hasNext()){
JobTimeOff jh= (JobTimeOff) it.next();
ValidationUtils.rejectIfEmptyOrWhitespace(errors, "startDateMonth", "required", "required");
System.out.println( "startDateMonth :" + jh.getStartDateMonth());
System.out.println( "text:" + jh.getText());
}




}

}
