If you look at java.sql.Types, you will see that Types.NULL is int 0 under the 
covers
and the error you are getting is because Derby is trying to extract TIMESTAMP 
value
from 0.

This is with the latest official release(10.0.2.1). running on java 5
and linux.
 

Actually, if you are trying to set null on a column with type timestamp 
, I think it should be

   insertPreparedStatement.setNull(5,Types.TIMESTAMP);
http://java.sun.com/j2se/1.4.2/docs/api/java/sql/PreparedStatement.html#setNull(int,%20int)
Hope this helps,

You would want to do it like this:

insertPreparedStatement.setNull(5,Types.TIMESTAMP); 

The type should be the type of the column.
