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
