Implementing a long running server process with status page

Flow

Hi,

I’d like to know what the optimal way of implementing a long running server process would be.

The use case is to have a screen that allows the user to upload (potentially hundreds of) documents, kick off a background based server process and then return control to the user. Then the user can navigate to another screen to see what the current upload status is.

Would I be better off using the standard spring approach of implementing an event listener or is there a better way to do this in Vaadin?

I’m using the latest version of Vaadin with Java 21.

Uploading files is separate thing, but for long-running tasks you might want to take a look at this recent blog post and examples for UIs.

Also, if you are interested in robust Java background processing framework, JobRunr is pretty popular.

Many thanks for the quick response. The “Really Long Actions” example is exactly what I was looking for.
