Example of starting vertx-vaadin explicitly from main() function

[sanel]

Hi,

I'm currently evaluating Vaadin with vert.x combination and vertx-vaadin looks like a perfect tool for that. I use Vaadin with Clojure, shipped in fatjar, which then manually starts Jetty and initializes VaadinServlet explicitly. The app is shipping built-in Jetty server and is run withjava -jar app.jar, where everything is started from Java's main() function.

Now, I'm looking for a similar approach with vertx-vaadin, but I can't find an example of how to start vert.x web server manually and load vertx-vaadin. Is this possible? In my case, I should be able to set a custom route for Vaadin app, as there are other routes outside of Vaadin context.

Also, reading from a blog post [1] @mcollovati, Vaadin with vertx-vaadin might have distributed session support out of the box. Is this still a work in progress, or can it be considered production ready?

Hi, I do not have an example ready, but you can follow any Vertx example that deploys a verticle.

Basically, you should just need to create a Vertx instance and deploy the VaadinVerticle (or a subclass).
Something like

Vertx vertx = Vertx.vertx();
vertx.deployVerticle(VaadinVerticle.class.getName())

In addition, you may provide configuration to both the Vertx instance and the VaadinVerticle.

For FAT jars you can use the vert.x Launcher, configuring the main verticle class on in the MANIFEST.MF file

About the distributed session support, it works for simple project, but I never tested with a real use case, so currently I could not define the support production ready.

BTW, thanks for the interest in the project!

Thank you very much for the details! Looking forward further playing with vertx-vaadin
