SpringComponentInjector and non-Wicket servlets
We are seeing an intermittent problem with our webapp, where we are seeing
the exception below. We have servlets other than Wicket's in our webapp,
which provide remote services. The problem seems to be that somehow the
Wicket proxy for a given Spring bean is being requested, perhaps from a
different thread than Wicket's. Is there a solution for this?
Any advice is appreciated.

Or use WicketSessionFilter to export the Application and Session to other
servlets
Hacky but ...

well, looks like com.hytrust.policy.update.DynamicUpdater is using a
proxy, is that a wicket class?

Igor, thanks for your reply. But that's the weird thing: we are not passing
those proxies to other services. We use the @SpringBean annotation only in
the UI code.

the proxies wicket generates are only to be used by wicket, so do not
pass those to other services.

Thanks to Vineet and Igor for your help. I think I have an idea about what
we've been doing wrong.

say you are using @springbean in a non component in a wicket thread
and you are using it in a non wicket thread too,
you can do something like below
if(Application.exists())
{
InjectorHolder.getInjector().inject(this);
}else{
//set service my way
service=ServicesFactory.getService();
}
