Re: What is the proper way to start a secondary process in Wicket 6
Dear All,
With the invaluable help of Martin Grigorov, I have summarized the
discussion on this thread on a small Wicket in Action article [1]. The
complete sample project can be found at [2].

@Martin,
Many thanks! I will try to have a look today at the PR and see if I find
the time to write the blogs article during this week.
Thanks again!

Hi Ernesto,
See https://github.com/reiern70/antilia-bits/pull/1
I've moved the code that exports the Application thread local to
TasksRunnable. This way it is possible to export the Session too.
The code looks good (after removing all annoying whitespaces :-) ). Now it
needs some explanation (i.e. blog article) ;-)

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);
}

No particular reason why I picked ScheduledThreadPoolExecutor other than it

Thread pools and such.
I used:
ThreadContext.detach();
instead of:
ThreadContext.setApplication(null);

On Thu,
Re: What is the proper way to start a secondary process in Wicket 6
Warren,
ThreadContext.detach(); seems to be more proper than...
ThreadContext.setApplication(null); I will update demo.

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);

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
your project and cherry picked out the code that I needed, I don’t
need all
the process progress code you have. I don’t really care what the

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
org.apache.wicket.WicketRuntimeException: There is no application

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 ?

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.

Ernesto, great job putting all that code together so quickly. I cloned your project and cherry picked out the code that I needed, I don’t need all the process progress code you have.

Re: What is the proper way to start a secondary process in Wicket 6
I have seen this from a 2010 post:
final Application app = Application.get();
final ExecutorService service = new ScheduledThreadPoolExecutor(1) {
@Override
protected void beforeExecute(final Thread t, final Runnable r) {
Application.set(app);
};
@Override
protected void afterExecute(final Runnable r, final Throwable t) {
Application.unset();
}
};
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 ?

Re: What is the proper way to start a secondary process in Wicket 6
After doing a little digging, I found the ThreadContext class.
ExecutorService executorService = new ScheduledThreadPoolExecutor(20)
{
@Override
protected void beforeExecute(Thread t, Runnable r) {
ThreadContext.setApplication(app);
}
@Override
protected void afterExecute(Runnable r, Throwable t) {
ThreadContext.detach();
}
};
That got rid of the initial no application attached to current thread …”
exception.
Is this the correct way of creating a new process when you need to use an
injected service in it ?

I just realized that part was missing... Look that when you create an
ExecutionBridge
you do in in a WEB thread. So you could do something like.
class ServcesHolder {
@Inject
private MyService service;
public ServicesHolder() {
Injector.get().inject(this);
}
// setter enad getter.
}
and
class ExecutionBridge {
private ServicesHolder hoolder;
public ExecutionBridge() {
// app will be in context and services injected ass this ei executed
in a web thread.
this.holder = new ServicesHolder();
}
}
from there on you could use your services via Services holder... No need to
have Application as a thread local.

the
proper way of doing this in Wicket 6 using an injected service.
Sometimes what I do is I create a context class ServiceHolder,
inject
what I need on this class (e.g. services) and pass this to the non
web
thread (e.g as an argument to the runnable). Injector.inject will
have
WicketApp in context.
1) Get request
2) Log some data (Do not wait for this to complete)
3) Process request
4) Return response
You could use the same ServiceHolder as a bridge to pass info to the
WEB
layer. 1) keep a reference to it 2) in another (polling) request
use it
to
see how back-ground job is progressing. Sometimes I also use it to
control
the Job: e.g. stop/pause it, cancel it. Once Job finishes just let
service
holder go.

I do not see a problem with the approach bellow But I normally op for
the solution I posted before.

After doing a little digging, I found the ThreadContext class.
ExecutorService executorService = new ScheduledThreadPoolExecutor(20)
{
@Override
protected void beforeExecute(Thread t, Runnable r) {
ThreadContext.setApplication(app);
}
@Override
protected void afterExecute(Runnable r, Throwable t) {
ThreadContext.detach();
}
};
That got rid of the initial no application attached to current thread …”
exception.
Is this the correct way of creating a new process when you need to use an
injected service in it ?

I have seen this from a 2010 post:
final Application app = Application.get();
final ExecutorService service = new
ScheduledThreadPoolExecutor(1) {
@Override
protected void beforeExecute(final Thread t, final Runnable
r) {
Application.set(app);
};
@Override
protected void afterExecute(final Runnable r, final Throwable
t) {
Application.unset();
}
};
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
your project and cherry picked out the code that I needed, I don’t need all
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
response.
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
org.apache.wicket.WicketRuntimeException: There is no application attached
to current 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 ?

Martin,

and
https://github.com/reiern70/antilia-bits/blob/master/bgprocess/src/main/java/com/antilia/panel/TasksListPanel.java#L70
I had to re-add Timer behavior: I do not see yet why? It is as if the
timer
is not re-rendered: they are not isTemporar :-( I will check when I have
more time.
I would appreciate if you can review the code... before I write anything
on
my fork of Wicket in Action. This probably could be done in a leaner way
mounting a resource to serve JSON for task states and building the UI at
client side... But example illustrates how to do it with plain Wicket.
