Passing parameter to date function in DB2

HI all
I need to find the difference between the date the user enters and the current date. and i used the below query to find it out.

i am using the prepared statement to pass the values to this query, using the
prepStmtOj.setObject(1,"2006-01-01");

i even tried hard coding the values but still i am getting the error.

Have anyone know what the reason. The format of the date i am passing in is valid one. i seen some examples using above date format.
