bypass quartz dispatcher only in certain asynchronous methods

[jonne.deprez]

In one part of my application I use a Richfaces progress bar to inform the user about the progress of a long running process. I based my work on the explanation in this thread.
The long running thread is a method annotated with @Asynchronous that continuously updates a field progress of the stateful bean it is a part of. From the moment the user click the 'Start' button, the asynchronous method is launched and the progress bar will poll the bean with a fixed interval to update its own value, until the process is finished. This works great.

But, since I activated Quartz in the same application, methods annotated by @Asynchronous are captured by the Quartz dispatcher. Arguments passed to an @Asynchronous method now all need to be Serializable, which wasn't the case in the progress bar method. Quartz now wants to store a reference to the asynchronous job in the database, which is not at all necessary.

So my question is: is there a way to bypass the quartz dispatcher for certain methods and to use it for others?

Not directly, however it would be pretty easy to manually use a different dispatcher.

I don't have access to the source at the moment, and I can't remember the exact steps, but I think the relevant class is ThreadPoolDispatcher. If there is only one method that you want to do this for you should be able to just use the dispatcher manually, if you are going to do it for a few different classes you can write your own interceptor.

If you want more help let me know and I will give a concrete example when I am on my dev machine.

Thanks. You gave me some ideas, but an example would still be highly appreciated!

The problem is that these dispatchers all have the same Seam name, and you can only install one at a time in components.xml. How can you manually use another dispatcher?

install it under another name and manually invoke the appropriate method. You will not be able to use the nice seam annotations but it will get the job done.
