IMO, as long as you get your conversation model correct, and you follow 0 , this should be very, very rare to need to do this. Like, super-rare. I would expect this to be rare in most desktop applications, but in general it is a case that you have got to be able to handle. Long running processing needs to be done asynchronously, in another thread, and its own conversation.
A Seam Asynchronous method is an easy way. Then you are left with the problem of getting the changes from the asynchronous thread back into the first conversation that we can from. There are two cases: a the async thread was able to make the changes persistent - then one approach is to just refresh the right objects in the original conversation b the async thread is not allowed to make the changes persistent - well, then you have to use merge Either case could be messy if you've let the user change the same objects that were changed by the async thread.
Of course we can't prove that either, but if you don't trust us, why would you want to refer people here? Long cookie duration.
If a customer comes from your site to ours, and then comes back to download six months later, you get credit. That's it! You send us business, we send you money! Signing up and getting your account configured couldn't be easier.
You can be referring business our way in as little as five minutes. The inevitable mismatch between your object-oriented code and the relational database requires you to write code that maps one to the other.
How it works?
This code is often complex, tedious and costly to develop. Hibernate does the mapping for you. Not only that, Hibernate makes it easy. Positioned as a layer between your application and your database, Hibernate takes care of loading and saving of objects.
Hibernate applications are cheaper, more portable, and more resilient to change. And they perform better than anything you are likely to develop yourself. A member of the core Hibernate developer team, Christian Bauer maintains the Hibernate documentation and website. He is a senior software engineer in Frankfurt, Germany.
Gavin King is the Hibernate founder and principal developer.

It can also be included as a feature in other programming languages. This code is often complex, tedious and costly to develop.
