Weld standalone SE and threads

pieter.martin Jan 22, 2010 5:47 PM

Hi,

I am trying to use Weld in a standalone SE app.

All is ok as long as I inject into objects running in the main thread.

If I try to @Inject application scoped objects into object running in another thread nothing happens. The variables remain null.

Is this kind of thing supported? In a way there needs to be a thread context and scope?

Thanks
Pieter

Ok, I was being an idiot using new Runnable et al. Using Instance..get() makes the injection work.

However I'd still like to know if a ThreadScope is possible?

Thanks
Pieter

I see there is some ThreadScope code in trunk, will have a look at that.

Cheers

Hi Pieter,

Yes there is support for Threads in SE but it's currently disabled due to a bug with Decorators. I think that bug has been recently closed, so hopefully I will get a chance to activate this ThreadContext support again soon.

Basically it is a decorator which wraps Runnable.run, activating the ThreadContext on a ThreadLocal before the call to run, and deactivating the context afterwards.

There are some example tests in the code which you may have already seen.

You will therefore need to activate the decorator in your beans.xml for it to work. I'll post more when I get it working again, and will hopefully add some documentation as well.

Cheers,

Pete.
