Oracle timestamp field insert row

I created an oracle table with a timestamp data type field in it. When I test the query template that inserts the row, I set the date field with a parameter value of "19-SEP-2007 10:02:00" and it works fine.

When I set the Param value in my javascript code to the same value, I get a sql insert error telling me the column length is to long.

Does anyoen have any ideas?
