Miri,
Can you share the URL that is sent to the server for that JSP. Or the JSP itself?

I found that , when i send null value for inputs i see this error , it works perfectly when i send real integer value .
these variables is declared as int in my class, you can see them above

<div class="row elanRow">
						<div class="col-md-4 col-sm-4 col-xs-12 elanRowLeft">
							<p><spring:message code='muherrik_hecmi' text='default text' />, a.g. <span>*</span></p>
						</div>
						<div class="col-md-8 col-sm-8 col-xs-12 elanRowRight">
							<input type="text" name="muherrik_hecmi_ag">
						</div>	
					</div>

I believe a member variable declared as 'int' cannot be null.  Change it to Integer (don't forget to update your getter/setter methods).
