How to set java.sql.Date to null ?

Hi there

I'm trying to pass a java.sql.Date parameter to a sql query using
JDBC-PostgreSQL interface. The problem shows up when I pass a null
java.sql.Date but as it happens in my application, the user may or may
not
enter the logDate.
(It works fine if the java.sql.Date(logDate) is a valid date).
Here is the code:

    PreparedStatement pstmt = null;
    try {
      pstmt = connect.prepareStatement("insert into prfs (prfNo, author,
severity, blockFunc, probArea, status, probDesc, logDate, estCompDate,
actCompDate, assigned, assignee,
 solution, attachment, siemensVar, reviewer) values " +
"(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)" );

      pstmt.setString(1,  prfNo);
      pstmt.setString(2,  author);
      pstmt.setInt(3,     severity);
      pstmt.setInt(4,     blockFunc);
      pstmt.setInt(5,     probArea);
      pstmt.setInt(6,     status);
      pstmt.setString(7,  probDesc);
-->   pstmt.setDate(8,    logDate); <-- NullPointerException ex
    } catch (SQLException e) { }


How do I set a Date to be a null ?

Thanks
