We had the same issue, and here's an example of the way that we implemented
the same sort of thing..... It could probably be made better, but it works
:)
First create your own request handler...
public class MyRequestCycle extends WebRequestCycle
{
protected Log log = LogFactory.getLog(this.getClass());
public MyRequestCycle(WebApplication application, WebRequest
request, Response response) {
super(application, request, response);
}
@Override
protected void onEndRequest() {
if(log.isDebugEnabled())
{
log.debug("In onEndRequest");
}
try
{
HibernateUtil.closeSession();
}
catch (PersistenceException e)
{
log.error(e);
}
super.onEndRequest();
}
...then reference it in your WebApplication (maybe in a abstract class)
public abstract class MyBaseApplication extends WebApplication
{
protected Log log = LogFactory.getLog(this.getClass());
@Override
public RequestCycle newRequestCycle(Request request, Response
response)
{
return new MyRequestCycle(this, (WebRequest)request,
(WebResponse)response);
}
I hope that this helps.

Ok :) I just had a look at DataBinder.net, that was more heavy-weght.
Is there any short introduction available on how to implement
onEndRequest() -hook, or is the best reference to just have a look at
the respective code of DataBinder.net?
