Since I had to look it up, maybe others did too:
POJO = Plain Old Java Object.
I'm guessing that means a Java object that doesn't need to know how it
is persisted in order to be stored? I.e., in Matt's case, the object
isn't modified to take ResultSet as an argument to the constructor.
K.C.
a POJO is just that. just an ordinary, everyday object. you might also
think of it as a traditional Java bean. it has an empty param
constructor, and get/setXXX signatures.

Everyday object?
You serious? Who uses those now? I mean it doesnt even come with 50,000 xml
files to specify deployment metainfo
s old fashioned!

iBatis I found much faster and simpler that others.

You could also consider using Torque. I believe it will generate a schema
from an existing database that will allow you build a set of data aware
objects. It also some good classes for working directly with XML. I wrote
a simple Struts plugin to work with Torque. It's not as cool as Hibernate

Thanks to all for your suggestions. I did some number comparisons b/w the
standard way (rs.next() ... set, set, set), ibatis, and
ResultSetUtils.getCollection() from scaffold. Here's what I found:
1. Standard way - 0.24 seconds
2. ibatis - 5+ seconds (ugh! - maybe I'm doing something wrong,
There are no people more expert in Struts than you Matt.
I think you can use RowSet to wrap a ResultSet, and RowSet has a
toCollection or getCollection method. (Or just don't user ResultSet at
all, just use RowSet, Sun has default implementation in JDC, but
Orcale has an extra download, other
Matt,
If you pull the scaffold project from
http://sourceforge.net/project/showfiles.php?group_id=49385, there is a
class called ResultSetUtils which provides the below methods for mapping a
ResultSet to a Collection of a given class or returning a given element from
the ResultSet. It uses
I'm about to try iBATIS www.ibatis.com for a new phase of a project we
started in Hibernate. Hibernate is cool, but I think something simpler
might be a better fit. (Not sure if we really need that finely grained
object layer after all :)
It will let you remove the SQL to a simple XML file and
We wrote something like this at work:
ResultSetTransformer is an interface with a single method:
public Object instanceFromRow(java.sql.ResultSet rset) throws
java.lang.Exception;
We mostly use a single implementation of the interface which we call
SimplePropertyMappedTransformerYou
I assume you don't mean something like:
brbr
List list = null;br
try {br
list = Collections.synchronizedList(new LinkedList());br
User user = null;br
CompositeEntity composite = new CompositeEntity();br
while(rs.next()) {br
user = composite.getUserVO();br
This is what I'm trying to get away from.

I might as well go ahead and state boldly what I was trying to imply,
Matt. If you notice the CompositeEntity, then you can imagine altering
that to include two changes to the norm. First, you can make all the
composite entities of the same type, and, second, you can change

Okay, gotcha. At least it had a List. LOL.

So far, I think I prefer JSTL's Result interface for this type of operation:
import javax.servlet.jsp.jstl.sql.Result;
import javax.servlet.jsp.jstl.sql.ResultSupport;
...
ResultSet rs = ...;
Result result = ResultSupport.toResult(rs);
request.setAttribute(result, result);
...
