Returning to the original page after session timeout / login
I've changed out PageExpiredErrorPage to be the login page for our app. Does wicket have any support built-in to help return the user to where they were after re-authenticating? From my modest understanding of Wicket, it would need to be a bookmarkable page, which will be ok for a good percentage of the pages in our system. Any suggestions? TIA!

Re: Returning to the original page after session timeout / login
Wow, I hope it's really that easy!?!
Should this work through an appserver restart? E.g. if I
1) login to the app
2) restart the app server
3) click a page link in the browser
Should this work? It didn't for me. Based on my limited understanding of
how wicket works and stepping into the code, it kinda looks like it might
not?

getting started with swarm/wasp - rendering links to secure pages
I have a question about rendering of links to secure pages when the user has not
been authenticated.
Based on this line from the tutorial:
In addition we granted links to our homepage the right to be clicked
(enable).
I expected the link to either be non-visible or non-clickable - since I did not
grant the
enable permission for this page until login. The link is enabled (though the
user is
redirected to the login page when clicked).
I've made my way through the getting-started guide
(http://wicketstuff.org/confluence/display/STUFFWIKI/Getting+started+with+Swarm)
and have a simple example working in my prototype. I have 3 pages:
- HomePage (non-secure)
- LoginPage (non-secure...obviously)
- Page2 (secure)
My authorization file looks like this:
grant principal org.apache.wicket.security.hive.authorization.SimplePrincipal
basic
{
permission
org.apache.wicket.security.hive.authorization.permissions.ComponentPermission
com.webperformance.portal.web.Page2, inherit, render;
permission
org.apache.wicket.security.hive.authorization.permissions.ComponentPermission
com.webperformance.portal.web.Page2, enable;
};
When the user logs in, they get the basic principal via a
UsernamePasswordContext.
I have a link from the HomePage to Page2 (secure page). When the HomePage
renders and the
user had not logged in, the link is enabled. Clicking the link does not take
the user to
the page - it takes them to the login page. I was expecting the link to be
disabled - so
you don't even get the clickable cursor for it. Am I simply mistaken in my
understanding
of what right to be clicked means? Or have I missed some crucial bit
somewhere to allow
it to function as I expected?
If user is not authorized for an action, we will either want links to be
disabled (i.e. non-
clickable) or be not rendered at all...depending on the context. Is this
something that
should be done via wasp/swarm or should I be doing this manually during page
construction?
TIA!
Chris

Re: singletons, pools, wicket, web services and architecture
It's a question we've wrestled with as well. It seemed remarkably inefficient to do XML encoding/decoding to move data from one part of the appserver to another. It seemed to make more sense to let the web UI skip past that and go straight to the business logic. Thanks!

Wouldn't it be easy to XMLize the services you're exposing remotely later if a different type of client would want to connect to it? I'd say just use Spring remoting (if you're using Spring). RMI would probably have been our (my) first choice, but is out due to firewall issues. Spring with the HTTP invoker was considered as well as some other more efficient HTTP and/or light-XML options. There are some organizational reasons to favor SOAP vs something simpler and there are plans to extend the service at some point to other organizations. We certainly _could_ do that later, but maintaining a 3rd interface down the road is not attractive in terms of maintenance cost. We would have to content with an installed user base - and therefore could not easily deprecate an unused interface.

using OpenJPA with wicket?
I'm just getting my feet wet with Wicket and OpenJPA. I've got the basics of both and have started prototyping parts of an upcoming project in each and everything was going great. Then I tried to put the two technologies together and hit a wall. I'd written the OpenJPA pieces in a standalone application. Moving to a web container (Tomcat), I saw a recommendation to annotate the servlet code with something like: @PersistenceUnit private EntityManagerFactory emf; Of course, with Wicket, we don't write a servlet...and now I'm drawing a blank as to where I should go next?.
