Re: What is the proper way to start a secondary process in Wicket 6
Warren,
Something like:
ExecutorService executorService = new ThreadPoolExecutor(10, 10,
0L, TimeUnit.MILLISECONDS,
new LinkedBlockingQueueRunnable()) {
@Override
protected void beforeExecute(final Thread t, final Runnable r) {
ThreadContext.setApplication(BgProcessApplication.this);
};
@Override
protected void afterExecute(final Runnable r, final Throwable t)
{
ThreadContext.setApplication(null);
}
};
seems to work.

But there is no more Application#set(app) and Application#unset() in
Wicket 6. Does Wicket 6 have some built in way of creating secondary
processes, maybe an internal thread pool that can be set-up ?

Ernesto, great job putting all that code together so quickly. I cloned

the process progress code you have. I don’t really care what the process
progress is or even if it completes ok, just don’t want it holding up my

I ended up using your ExecutionBridge, TasksRunnable, and ITask classes
and interfaces. But I still don’t know where and how to inject my service
into this new task/thread or ExecutionBridge without getting this exception:
Exception in thread pool-1-thread-1

Do I need to get the application attached to my new threads somehow so I
can use my injected service, and if so, how do I do that ?

I would appreciate if you can review the code... before I write anything on

mounting a resource to serve JSON for task states and building the UI at

This
Auto-reloading markup during development
Hi all, Is it possible to set wicket to reload markup and other resources during development so that one does not need to redeploy-restart the server in order to see their changes? I have figured out how to do the equivalent for changes in java code using DCEVM but I can't seem to make it work for wicket's content files. I'm working with eclipse and tomcat. Thanks in advance, Marios
Re: What is the proper way to start a secondary process in Wicket 6
Ernesto,
That’s kind of what I ended up doing except with a different ThreadPoolExecutor
implementation.
ExecutorService executorService = new ScheduledThreadPoolExecutor(20)
{
@Override
protected void beforeExecute(Thread t, Runnable r) {
ThreadContext.setApplication(MyApplication.this);
}
@Override
protected void afterExecute(Runnable r, Throwable t) {
ThreadContext.detach();
}
};
No particular reason why I picked ScheduledThreadPoolExecutor other than it
looked a little easier to use. I need to look more into the different types of
Thread pools and such.
I used:
ThreadContext.detach();
instead of:
ThreadContext.setApplication(null);

ThreadContext.detach(); seems to be more proper than...
ThreadContext.setApplication(null); I will update demo.
