RequestCycle?

[Stanczak Group <ju...@stanczakgroup.com>]

How can I access the request cycle so I can open and close a Hibernate 
session on each request?

I see DataBinder is just casting them and using WebRequestCycle, is that 
the right way?

If I create my own request cycle, then what class do I extend? 
RequestCycle, WebRequestCycle or... ? RequestCycle requires you to 
implement other methods? Is there a wrapper class?

Yeah, that happened to me this week as well, but it was working over the
weekend as well as this morning, so try it again.

Re: Re[2]: RequestCycle?

[Martijn Dashorst <ma...@gmail.com>]

Works for me... Apparently Nathan (or his ISP) has shut down the
pingd. The website is still alive!

Martijn

Result of the page in my browser:

Toolkit overview
Databinder is a Java programming toolkit for data–driven Web
applications. It's based upon the Wicket Web component framework and
Hibernate object-relational mapping service. Generally preferring
creativity over convention, Databinder's aim is to facilitate database
programming for the Web that is straightforward, pleasant, and
flexible.
How it works
Databinder provides you with Wicket models that populate themselves
using a lightly managed Hibernate session, and a collection of view
components that bind to them automatically. In your application,
instances of annotated data classes rest in these models, rendering
(and updating) through a view component tree and plain HTML templates.

I don't know that 1.1 has a tar.  My project uses maven, so it was a snap to
add the Databinder bits to our pom.

Here is the page that gives the databinder snapshot repo info:
http://databinder.net/site/show/faq#updates

If you don't use maven, I could always send a 1.1-SNAPSHOT directly to
you...

FYI, The databinder site has some examples that help with learning how to
use and adapt the code to your own project.

Probably not. I'll probably use it when I get a chance. I just 
downloaded the 1.0 tar and saw it's using 1.2 Wicket. Shot me the link 
and I'll see if I can give it a shot tonight.

DataBinder (1.1-SNAPSHOT) definitely works with 1.3.  Databinder also does a
pretty good job of integrating Hibernate into the Wicket models.  Is there a
use case for which Databinder does not work for you?

I'm not for sure what to use. I tried to override the newRequestCycle() 
but I had trouble understanding it. I'm doing something like what 
DataBinder does, but with 1.3. DataBinder seems to be 1.2. Either way 
I'd rather use my own. Does anyone have an example of providing my own 
request cycle, or is there an easier way?

I think it is setup with ThreadLocal so you can get it easily with
RequestCycle.get(). You can also provide your own version from
Application.newRequestCycle which might be more what you need to hook in
start/end events.

Ok, thanks. This is what I did.

public class RequestCycleImpl extends WebRequestCycle {

    private Session hibernateSession;

    public RequestCycleImpl(Application application, Request request, 
Response response) {
        super(application, (WebRequest) request, response);
    }

    @Override
    protected void onBeginRequest() {
        this.hibernateSession = 
HibernateUtil.getSessionFactory().openSession();
    }

    @Override
    protected void onEndRequest() {
        if (this.hibernateSession != null) {
            this.hibernateSession.close();
        }
    }

    public Session getHibernateSession() {
        return hibernateSession;
    }
}

In your application class:

	@Override
	public RequestCycle newRequestCycle(Request request, Response response)
	{
		return new WebRequestCycle(this, (WebRequest)request, response)
		{
			@Override
			protected void onBeginRequest()
			{
				// open session
			}

			@Override
			protected void onEndRequest()
			{
				// close session
			}
		};
	}

If you use Spring for instance, you could just configure the hibernate
session filter that comes with it instead.
