Hi friend,

We check your code having some error and do some changes in your code.

Wrong Code in your script :

1)

<script type="text/javascript">
function myFunc3() {
var n='<%=dt%>'
if(n!=null) {
document.myform.dt.value=n
}

}
</script>

====var n='<%=dt%>'======

You have not embed jsp code not in javascript.

=========================================================================
2)

Date dt =new SimpleDateFormat("mm/dd/yyyy").parse(request.getParameter("dt"));

Replace with the code

String strformat="mm/dd/yyyy";
SimpleDateFormat formatter = new SimpleDateFormat(strformat);
java.util.Date dateStr = formatter.parse(startDate);
String formattedDate = formatter.format(dateStr);
java.util.Date fmtDate = formatter.parse(formattedDate);
formatter = new SimpleDateFormat("yyyy-mm-dd");
String dt = formatter.format(fmtDate);

=========================================================================

3)

java.sql.PreparedStatement stmt = con.prepareStatement("insert into SYSTEM.IMS_MEETING values(id,?,st,ed,dt,?,?,s);");

You have not set parameter accorinding to the prepared statment.
