postgres.stat.result exception

Hi

I am having a problem using a stored procedure/function in postgres ver 7.2.2

My JDBC code is as follows
----------------------------------------------------------------------------------------------------------
Connection conn = null;
CallableStatement cs = null;
try{
conn = DatabaseAccess.CreateDBConnection() ;

cs = conn.prepareCall("{? = call Save_Status(?)}");
cs.registerOutParameter(1,java.sql.Types.INTEGER);
cs.setString(2,strStatus);
int iStatus = cs.executeUpdate();
................
}
---------------------------------------------------------------------------------------------------------
The function is written as follows
------------------------------------------------------------------------------------------------------------------------------
CREATE FUNCTION save_status(varchar) RETURNS int4 AS '
Begin
update TA_REGISTRATION_DATA SET REG_STATUS = $1 WHERE REG_ID = 1;
return 0;
END;
' LANGUAGE 'plpgsql';
------------------------------------------------------------------------------------------------------------------------------
The update to the postgresql database succeeds but a postgresql.stat.result exception is thrown.
What do I need to modify in my JAVA code/function to avoid this exception.

Thanks and Regards
Tanu
