-----------------------------------

Oops... make that

                	stmt.setObject(14, booleanValue, Types.BOOLEAN);

>      Project: Daisy
>         Type: Bug
>   Components: Repository
>     Versions: public - 1.4
>  Environment: os: Windows XP
> db: Derby 10.1
>     Reporter: pan LI
>     Priority: Minor

> In 
> LocalDocumentStrategy.storeFields(DocumentImpl document, long documentId, long versionId, Connection conn) 
> there is:
>                     stmt.setObject(9, dateValue);
>                     stmt.setObject(10, datetimeValue);
>                     stmt.setObject(11, integerValue);
>                     stmt.setObject(12, floatValue);
>                     stmt.setBigDecimal(13, decimalValue);
>                     stmt.setObject(14, booleanValue);
> All of the values can be null. As the jdbc doc suggested, we should use stmt.setNull(9, Types.DATE) to set null value to a data field.  Some databases don't care, but some databases(in my case, Derby) , this will end in a JDBC exception
> I have changed it to :
> if (dateValue != null) {
>                         stmt.setObject(9, dateValue);                        
>                     } else {
>                         stmt.setNull(9, Types.DATE);
>                     }
>                     if (datetimeValue != null) {
>                         stmt.setObject(10, datetimeValue);
>                     } else {
>                         stmt.setNull(10, Types.TIMESTAMP);
>                     }
>                     if (integerValue != null) {
>                         stmt.setObject(11, integerValue);
>                     } else {

>                     }

>                         stmt.setObject(12, floatValue);
>                     } else {
>                         stmt.setNull(12, Types.FLOAT);
>                     }
>                     if (decimalValue != null) {
>                         stmt.setObject(13, decimalValue);
>                     } else {

>                     } else {
