[jira] [Commented] (WICKET-5004) Add light-weight possibility to generate URLs from Page and PageParameters without having the WebApplication actually running.

Peter Parson commented on WICKET-5004:
--------------------------------------

For the sake of completeness: I have also posted a stackoverflow question about this: http://stackoverflow.com/a/13088148/1006823

In the answer I have outlined how I finally solved the problem. I just had to extract the actual page mounting out of my WebApplication class, which seemed like a drawback first, but actually I am pretty happy that the mount stuff is separate now :)

That said, feel free to close this ticket if you do not think the framework should support this.
At anyone needing this, have a look at the link above - actually it is pretty simple once you know it :)

> In certain scenarios it is useful to be able to generate wicket URLs without having the wicket application running, i.e. a mail notification system running which needs to include dynamic URLs in the mails, or an XML sitemap generator running on a different server.
> With Wicket 1.3.x, this was an easy task: we just needed to (statically) provide the UrlRequestCodingStrategy, the PageClass and PageParameters and any other module depending on our wicket module could obtain the URLs.
> With Wicket 6.x it's not so easy, it seems to be impossible without having the application actually running. I have found the solution I have described here: http://stackoverflow.com/questions/13015743/how-to-obtain-wicket-url-from-pageclass-and-pageparameters-without-running-wicke
> But this seems to be a little hacky, and causes problems if executed multiple times (since the WebApplication is somewhere registered within the context, but cannot be destroyed)
> A code example from our old (1.3.x) solution, to give you an idea of what we did.
> We had a spring bean in our Wicket module which offered methods like this:
> public String getUrlFor(MyDomainObject o) {
> 	Class pClass = MyDomainObjectTargetPage.class;
> 	PageParameters pp = MyDomainObjectTargetPage.pageParametersFor(o);
> 	IRequestTargetUrlCodingStrategy urlCodingStragy = MyDomainObjectTargetPage.URL_CODING_STRATEGY;
> 	BookmarkablePageRequestTarget target = new BookmarkablePageRequestTarget(pClass, pp);
> 	return "/" + urlCodingStragy.encode(target).toString()
> }
