Servlet and Wicket
We have significant Servlet JSP investment in our major development efforts.
Now, we want to switch from JSP to Wicket. Because of request dispatching
and current investment from http to servlet connectivity we want to reuse
the servlet components and swap out just the JSP with Wicket.
Is there a way to make this work? The investment in Servlet development is
significant. Therefore we want to reuse them. If cannot, we may have to
continue with JSP. If someone know how we can integrate Servlet and Wicket
in the presentation layer please let me know. Your response is very much
appreciated.

Re: Servlet and Wicket
Posted by "kohaeri@gmail.com" <ko...@gmail.com>.
In my implementation I have in the presentation layer I have:
Interfacing with Http web Server (with IIS and apache http server)
Dispatcher Servlet
(awaiting incoming httpservletRequest)
|
Wicket Components
On the Application Service layer, I have
EJB Beans
And then on the Data Layer I have
JPA/Entity
My question is what should I be concerned about in accessing Wicket
Components from the Servlets since the URL would be connecting
directly to servlets.
I know how this works with JSP but I don't know how to access Wicket
apps from Servlets. Any examples you have would be helpful. We have to
have the Servlet in from due to current connection from IIS and
Apache. Your help or best practices on this would be appreciated.

wicket and servlets can live side-by-side. wicket doesnt take over the
url space so servlets and jsps can still be accessed like they used to
be.

Thank you for all of you who responded. See here the architecture we are

i would suggest you, hohaeri, to do the migration progressively, by
keeping your servlet-application living with your new
wicket-application, while translating one by one your pages from the
first to the latter, til finally have all your application fully
migrated. if you have correctly done SoC in your current application
(business objects, integration layer, components...) then moving from
your servlet-app to the new wicket-app wouldn't be so painful. if this
is not the case, then "just re-do it" all... probably it may worth it
;-)

No that was not was I was saying. I am just advising you to let Wicket
manage complete pages, instead of parts of pages composed within another
servlet architecture. I would give you the same advise if you were using
JSF instead.

Are you saying that I can either use Wicket without Servlet or use Servlet
with JSP/JSF just like our previous implementation?
I thought Wicket components would work under a Servlet environment. If
Wicket cannot run under Servlet then, I would like to know now so that we
can consider JSF instead. Your response is appreciated.

That doesn't make any sense. For IIS and Apache it really doesn't matter

I would never advice to do it this way. If you want to keep your
application in a request-based dispatcher kind of architecture, than
don't use wicket. If your reason for moving to wicket is to have better
maintainable software, then by all means, don't rebuild everything
exactly the same in wicket.

Hi..
I understood what your issue is. Just want to share my experience here.
I used to convert my struts application to wicket. I found there were no easy way to solve this matter. Since wicket is component based, not rely on servlet to do an action.
Finally, I ended this matter by recreating all the jsp page to wicket page one by one.
The html dan css structure were still usable. Just need reform the page with wicket style.
Other things like form action servlet, link, etc are not much usable except the business logic.
The way jsp do page templating (e.g. tiles or sitemesh) was also not usable. In wicket we do inheritance or border to do page templating.
My conclusion, this is not an easy thing to do. But if you really want to, you really need to spent time to reform your presentation. It can be a pain if your project is huge size.
I know I didn't share any solution here, just shared my thoughts.
Hope others have solution for you.
Cheers,
Noven
