DTO pattern and WrapDynaBean

[Ovidiu EFTIMIE <oe...@assemblee-nat.fr>]

 Hi,
I've used until now the DTO pattern to transfer data from action forms to the
bussines layer , but I was wondering if using WrapDynaBean (that I've just
discovered) to wrap the action form an to pass it in a DAO class would have
a major inpact on performance.

For example:
===> in an Action (DocumentAction)

DocumentForm dcForm = (DocumentForm)form;
DynaBean wrp = new WrapDynaBean(dcForm);

DocumentDAO dbo = new DocumentDAO();

dom.insertDocument(getConnection(),wrp);


===>and then in the DAO class
public int insertDocument(Connection conn, DynaBean data){
    StringBuffer sbf = new StringBuffer();
    sbf.append("insert ......").appen(data.get("title")).append(",")
         .append(data.get("author")).append(")");
............................................
}

Anyone has any comments?
Thanx
Ovidiu
