Hibernate Insert Failing...

Hi All,

I'm a beginner with Hibernate and I'm having trouble understanding how
to insert dates into an Oracle database properly. In my Struts
application I have my Defect Class (a portion of which is shown
below). The relevant portion of my Hibernate Defect.hbm.xml is also
shown below. When I fill out my .jsp and submit it . . . I get this
error:

"java.lang.IllegalArgumentException: Cannot
invoke ....Defect.setReportdatetime - argument type mismatch"

I don't understand how to do this. Can someone straighten me out?

Thanks,

Andy

********** Relevant part of Form Bean **************************

public class Defect extends ActionForm
{
    //Form Bean For the Defect Entry Screen

    private Date reportdatetime;

    public Date getReportdatetime()
                {
        return reportdatetime;
    }

                public void setReportdatetime(Date reportdatetime)
                {
        this.reportdatetime = reportdatetime;
    }

********** Relevant part of Defect.hbm.xml **************************

<class name="Defect" table="Defect">
    <id name="Defectid" type="integer" column="DEFECTID">
        <generator class="native"/>
    </id>
    <property name="Reportdatetime"/>
    <property name="Reporteruserid"/>
