Vaadin Flow and Apache Karaf

Julian Feinauer

Hi all,

 

we use the Vaadin Framework [1] in multiple projects as Frontend technology.

As I just recently started with Karaf I wanted to build a small example app based on Vaadin and OSGI.

Although Vaadin claims to have OSGi support [2], it really doesn’t feel well documented, properly tested and up to date. And it is lacking a good Karaf integration like a feature or so.

An Example project is shown here [3] but its very implicit (uses embedded Felix and tons of maven shenanigans as it looks).

 

Does anyone here have experience with Vaadin or an idea on how one would approach a Vaadin-OSGi Application?

 

Thanks!

Julian

Hi Julian,

I don't have personal experience but I helped some guys on Vaadin.

IMHO, Vaadin should provide a clean features XML.

This is one that I created for Vaadin 7:

<?xml version="1.0" encoding="UTF-8"?>

</features>

It's not up to date, but could be a good starting point to update ;)

I would propose a updated features XML as Vaadin PR.

Re: Vaadin Flow and Apache Karaf

Julian Feinauer
Hi JB,

thank you very much for  the fast reply.
Indeed, I agree that a vaadin feature as PR to vaadin would be the best way.
So I'll check your feature and see what I can do from it.

Really appreciated!
Julian

My ukelonn web application[1] has gone through several iterations:
 1. A JSF application using PrimeFaces[2] (started in July 2016 and
    abandoned in December 2016)
 2. A Vaadin application[3] (on master from December 2016 abandoned in August 2018)
 3. A react.js application, with a REST API written using jersey[4],
    initially (ie from August 2018 to July 2019) styled with Material
    Design Lite (MDL)[5], but currently  styled with bootstrap 4[6]

In Vaadin I was using an extension called TouchKit[7] to get a mobile
app'ish look on the application.  However TouchKit was kind of, sort of,
abandoned when moving to Vaadin 8.  I tried getting the open sourced
version of TouchKit[8] working, providing some Pull Requests to the
project.

But I never got the Vaadin8 version working[9], and sometime in the spring
of 2018 gave up on TouchKit and started moving towards making ukelonn a
react.js application, backed a REST API.

And that approach proved to be so much conceptually simpler and so much
easier to maintain, that I will never be going back again, I think.

(I may switch react.js with something else, like Vue.js or Svelte.js,
but for now react/redux with sagas seems like the simplest to program
and debug)

If anyone are interest I can try to outline the architecture of the
react.js solution (can't do the same for the older versions,
unfortunately, because I can't quite remember how they were put
together...:-) ).

Thanks for the update Julian.

I will take a look on vaadin example, and eventually update it if needed.

I keep you posted.

Re: Vaadin Flow and Apache Karaf

Julian Feinauer
Hey,

I decided to post again an update just to learn something... : )
The Demo I posted sets up a felix instance with the bundles listed below.

I am able to start that in karaf If I copy all over to deploy BUT its not working due to NPEs or stuff and I guess there are some conflicts as things like the servlet container are already in a karaf bundle...

Could it be possible to just take out some jars (and add some bundles / features to karaf) and then make the whole thing run?

Re: Vaadin Flow and Apache Karaf

Mike-2
Hello Julian,

I had a similar problem using vaadin flow with karaf and created a post a few months ago. Maybe it will help.


Regards,
Mike

Hey,

I decided to post again an update just to learn something... : )
The Demo I posted sets up a felix instance with the bundles listed below.

I am able to start that in karaf If I copy all over to deploy BUT its not working due to NPEs or stuff and I guess there are some conflicts as things like the servlet container are already in a karaf bundle...

Could it be possible to just take out some jars (and add some bundles / features to karaf) and then make the whole thing run?

   Thanks for the update Julian.

   I will take a look on vaadin example, and eventually update it if needed.

   I keep you posted.

Hey, short update on that one…



In fact, I quickly went through it and I didn’t get much out of it (in
fact, I didn’t even get it to run).

But what there is now, is this vaadin example for OSGi which is not that
great… I think.

Its located here:



https://github.com/vaadin/base-starter-flow-osgi/commit/47aac30104092a15c2744e39e6ed10a79d11ea12



(this is the last version for the vaadin 13.x.x release).



I get it to start its own felix distro and show the site.

Is there an ‘easy’ trick to get all necessary parts out of it for a
karaf feature?

I didn’t get it straightforward as it brings its own jetty and stuff
which leads then to some NPEs in my karaf setup.



Any help is appreciated!

Julian
