Change your mutator to accept a String and perform the conversion yourself. Then you can check for null or empty string before you start the conversion. (*Chris*)

I have a form with a date input field. This field is NOT mandatory, this means it can contain a value or be empty. Whenever the user does NOT fill in this datefield I get the following exception: javax.servlet.ServletException: BeanUtils.populate org.apache.struts.util.RequestUtils.populate(RequestUtils.java:495) org.apache.struts.action.RequestProcessor.processPopulate( RequestProcessor.java:805) org.apache.struts.action.RequestProcessor.process(RequestProcessor.java :203) org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194) org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:432) javax.servlet.http.HttpServlet.service(HttpServlet.java:709) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) root cause org.apache.commons.beanutils.ConversionException org.apache.commons.beanutils.converters.SqlDateConverter.convert( SqlDateConverter.java:117) org.apache.commons.beanutils.ConvertUtilsBean.convert( ConvertUtilsBean.java:428) org.apache.commons.beanutils.BeanUtilsBean.setProperty(BeanUtilsBean.java :1004) org.apache.commons.beanutils.BeanUtilsBean.populate(BeanUtilsBean.java :811) org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:298) org.apache.struts.util.RequestUtils.populate(RequestUtils.java:493) My form is defined as follows: <form-bean name="vehicleForm" type="ch.smartsol.struts.form.VehicleForm"/> and in Java: public class VehicleForm extends ValidatorActionForm { ... private Date dateOfCommissioning = null; ... } OK, the form member is of type Java.sql.Date and the form sends a String. Questions: ========== - WHEN does the conversion from string to Date take place? - How can I deal with empty strings in case the user does NOT fill in this date field? Many thanks for your help!
