Re: Wicket resources (css, js and images)?
Hi Jeremy, On Sat, Dec 18, 2010 at 6:53 AM, Jeremy Thomerson jer...@wickettraining.com wrote: Also worth mentioning, there are two other example decorating header responses that I committed into core for you to build on: 1 - ResourceReferenceDependencyInjectingHeaderResponse - which allows you to create a IResourceReferenceDependencyConfigurationService which defines dependencies for your resource references. For instance, wicket-ajax.js depends on wicket-event.js. So, everywhere that we render a reference to wicket-ajax.js, we must be sure that a reference to wicket-event.js is also rendered. However, with the ResourceReferenceDependencyInjectingHeaderResponse, you can make this automatic. This is probably only worth the additional effort if you have many such reference dependencies. 2 - HeaderResponseContainerFilteringHeaderResponse - allows you to filter resource references into different buckets. One of these buckets is then rendered into the standard Wicket head location. The others can be rendered wherever you want in the page by embedding a HeaderResponseFilteredResponseContainer in your page. This is useful if you want CSS to appear in the header and JS just before the /body tag in your app (a recommendation by UI experts to decrease page load time). There is a default JavascriptFilteredIntoFooterHeaderResponse that performs the described header / footer split. -- Jeremy Thomerson http://wickettraining.com Need a CMS for Wicket?

See Application#setHeaderResponseDecorator. You can use this to create your own IHeaderResponse and intercept all calls to render JS / CSS references. Then, you could do smart things like keep all the references around until the end of the request (or actually, the renderHead traversal), and at that point, build a URL that references an aggregate of all requested CSS / JS resources. As Hielke mentioned, you then have problems because every page has a different combo of resources. So, I provided AbstractResourceAggregatingHeaderResponse that provides a framework for grouping resource references into aggregate groups. Now, your developer can specify groups for references. What groups you specify are totally up to you. The idea is that you group things that will be on every page into a group, and then the things that change on each page into another group. So, you get to take advantage of the browser caching for those things that are on every page. You can go further if you'd like. So, you could do something like the following to specify groups and load orders (things within a certain group may still need to be loaded before / after other things in same group). // example of things that may be shared for all your applications across your company, etc...: response.renderCSSReference(new GroupedAndOrderedResourceReference(ResourceGroup.GLOBAL, 0, HomePage.class, footer.css)); response.renderCSSReference(new GroupedAndOrderedResourceReference(ResourceGroup.GLOBAL, 0, HomePage.class, header.css)); // example of something that may be in this single application: response.renderCSSReference(new GroupedAndOrderedResourceReference(ResourceGroup.APPLICATION, 0, HomePage.class, app.css)); I've put together a working quickstart example of this. You can download it and play with it. http://wickettraining.com/attachments/resourceaggregation.tar.gz Do you mind if we use this code for a new wicket-example application ? With some work, a standard set of aggregation groups could be defined, and this could be rolled into core. If someone wants to spearhead that, I would love it and do anything I can to assist. PS - In an ideal world, you wouldn't even need to specify the groups manually. You could have a smart algorithm that used each request to learn what things always appear together. The algorithm would start grouping things that commonly appear together into groups automatically. The first few requests wouldn't really group much, but as the requests continue, you would build better and better groups. I think we should create a Wiki page with this description and add an entry in migrate-to-1.5 with a link to that page. I'll do it later today or tomorrow. -- Jeremy Thomerson http://wickettraining.com Need a CMS for Wicket?

How to programmatically get PlatformTransactionManager of a DAO ?
I am developing a generic CRUD app , that can edit any Spring/JPA entities
with a AbstractDao pattern's implementation , such as UserDaoImpl ,
ForumDaoImpl ...etc
In my wicket page : I have to use @SpringBean to identify which
PlatformTransactionManager to use , such as :
@SpringBean(name=transactionManagerUser)
private PlatformTransactionManager transactionManagerUser;
private TransactionTemplate txTemplate;
public CrudPage(final PageParameters pps , final AbstractDaoT dao)
{
super(pps);
txTemplate= new TransactionTemplate(transactionManagerUser);
}
The problem is , these DAOs are using different transaction managers , such
astransactionManagerUser , transactionManagerForum ...etc.
I cannot hard-code these txManager's name in my code. I have to
programmatically get the dao's txManager . How to achieve that ?
Thanks a lot !

Use declarative transaction management instead

Thanks. but declarative txManagement add a lot of complexity to XMLs Is there any other option ? 2010/12/19 James Carman ja...@carmanconsulting.com declarative transaction management

Assigning a new Session does not change Session.ID
Hello Wicket community,
I'm relatively new to Wicket and I have a problem that I have not been
able to solve so far by means of Google and crawling through the user
mailing list archive.
What I want to do is change or replace the current Session of somebody
using my Wicket web application.
After having found this discussion
(https://issues.apache.org/jira/browse/WICKET-1767), the task at hand
was pretty simple.
Here's how I do it:
...
private void assignNewSession() {
log.debug(Assigning new session to user.);
RequestCycle.get().getSession().replaceSession();
}
...
This also works perfectly if I try it out in a browser. I can see, that
the session ID changes, as soon as this code has been executed.
What I have not been able to do so far, however, is finding a way to
Unit-test, if the session has really been changed.
If I, for instance, include the following lines in the method above:
...
private void assignNewSession() {
log.debug(Assigning new session to user.);
Session oldSession = RequestCycle.get().getSession();
String oldSessionID = oldSession.getId();
// same way of replacing session as above
RequestCycle.get().getSession().replaceSession();
Session newSession = RequestCycle.get().getSession();
String newSessionID = newSession.getId();
System.out.println(oldSession == newSession);
System.out.println(oldSessionID == newSessionID);
}
...
then I will find that the ID of the Session I'm getting from the
RequestCycle has not changed at all. The oldSession and newSession
objects are even the same object.
So, my question is:
Why does the code replacing the Session work when executed within the
browser? But why can't I seem to reproduce the replacement of the
session or a change in the session id with that piece of code?
Does the session stay the same within one request cycle, and will it
only change when the next request is issued (a difference I can see
between the code above and running the same thing in a browser)?
I would be very grateful if you could try to explain this behavior to me
in order to give me a better understanding of what Wicket is doing here
and why, with my approach, I don't seem to be able to generate the
result expected by me.
Also, if you could probably point out any way that I could actually use
to unit-test the replacement of a session, that would be very helpful.
Thanks in advance,
Andreas Maly

Use the source, Luke! That's the great thing about open source. You can read it to see what's going on and perhaps learn something along the way.

If you still can't figure it out, by all means, ping the list again. I'm sorry, I forgot to mention in my first post that I already dug quite deep into the code and had a look at quite a bit of code from the Session, RequestCycle and what not classes. I definitely agree with you, that one can learn lots of things from other people's code. So I did from diggin in the Wicket code. I'd say, I understood quite a few pieces of that code, but however it did not help me to grasp the bigger picture in terms of how it all plays together. I also got to confess, that I don't have much experience yet with web programming, so I stopped digging into the code about when I left Wicket and got down to e.g. HttpRequests. So if anybody could give me that bigger picture, nudge me in the right direction, or tell me what crucial point I have been missing, I'd still be very thankful.
