Getting started with Toplink--is it possible for my infrastructure?

Question

Hello
We are on Release 1 of Portal (yes! we know this is an old version--long story!) Anyhow, I am able to use the latest Jdev product and switch the classes back to JDK 1.4 before deployment and it all works. We have a new 10g R2 database server that is a separate server that we hold our app data within that we access form applications (both portlets as well as stand alone OC4Js) deployed to our Oracle Portal server.
Because of the old version of the Portal software, I already know I cannot take advantage of ADF in my apps. However, I would still like to use TopLink if possible--well I think I do anyhow...so am looking for some good advice from seasoned Jdev/Toplink folks.
I think TopLink will build all my java classes for my database objects and provide some manner of standardizing how I access/update/etc the data in the database objects via my applications. However, can I do this without all the other ADF stuff in place?

Thanks for info. I have a few more questions.
I created the Session Bean, but I still don't know how to access any of what i've created from the JSP. I found some code on the web that leads me to believe I must use EJB3.0 and that is not compatible with our version of Portal. I'm a beginner in this realm, so if you could spell it all out in some level of detail that would help me a great deal.
The session bean created has a method in it like this:
public List<Component> findAllComponent() {
Session session = getSessionFactory().acquireSession();
List<Component> results =
(List<Component>)session.executeQuery("findAllComponent", Component.class);session.release();
// Uncomment the following lines of code if the results from this query will be mutated.
// See SessionFactory.detach() for more information.
// results = (java.util.List<ERep.Component>)getSessionFactory().detach(results);
return results;
The "Component" is the TopLink class I created.
My questions are still, how do I get a stateful connection to the TopLink class Component and then access to the methods in it from a JSP?
