Thanks for your answer! There is no hurry. I will add a service to the mix to cover Warrent use case. Eg using Guice integration.

(Stupid) license questions
Are there any requirements on what license (if any) code that uses Wicket must be released under and what acknowledgements (if any) must be provided? Does it differ depending on the nature of what is being released? (e.g. whole apps that use Wicket vs individual, only slightly modified copies of Wicket components)

Bes practice for deployment to avoid ClassNotFoundException
Hi all, I'm new to wicket and just recently started to use it for a new web app for one of our projects. Today I came across a similar issue like described in [1], a ClassNotFoundException during deserialization of a page. The interesting part about this in my mind is, that the mentioned missing class was missing for a good reason: I simply refactored a bit and renamed the class, redeployed and restarted my Tomcat. This looks like a normal use case to me, but is something I didn't thought of when I've read through the docs because. My deployment is very simple: I check out a SVN working copy with a pre-configured tag containing the whole application once and afterwards just need to merge/update and stop/start the web server/app. How is deployment supposed to work in Wicket after I have refactored or otherwise changed my classes regarding cached and serialized pages? Is there anything I need to tell wicket to clear its caches on each deployment or ignore those or whatever? Am I forced to not delete once deployed classes for a fair period of time? That would be a litte nightmare... Or is there any other issue I ran into I should have avoided? Obviously others do deploy their Wicket apps as well, so I hope you have some input on how to avoid the problem I've ran into. Thanks!

Re: What is the proper way to start a secondary process in Wicket 6
Ernesto, I am not sure that creating a service holder will do the trick without still attaching the app to the new thread. I am currently injecting a service into your ExecutionBridge class that is instantiated in the request thread. All is good until that ExecutionBridge gets passed to the new thread. Injecting the service in a Service holder is the same thing, isn’t it ? I haven’t tried attaching the app to the new thread and injecting the service straight into the new task/thread itself. I think that would be cleaner. I will try that out.

Re: What is the proper way to start a secondary process in Wicket 6
Warren, Service holder will be created in a WEB thread, so WebApplication will be in context as a thread local. Mind that cosntructor of servce holder will cal Injector.get().inject... too inject the services. After that unless you need it for something else... you no longer need WebApplicatiion. Also if your sevices has no state Service holder could be a singleton that is created on application init and just shared by all bridges.
