Where can I find the Hawtio server side static resources for embedding in my application?

[David Hoffer]

How can I include Hawtio in my Vertx application?

http://hawt.io/ says the following...

The only server side dependency (other than the static HTML/CSS/JS/images) is the excellent Jolokia library which is available as a JVM agent...

I already have Jolokia in my Vertx application but now I need the above referenced 'static HTML/CSS/JS/images' where can I get these to include in my application?  

Are these perhaps available as a webjar where I could get the static UI contents?

Hi Dave,

Can you try the embedded mode?

http://hawt.io/docs/get-started/#using-hawtio-embedded-in-a-java-application

You still need to put hawtio.war somewhere but it should work with Vert.x.

Vert.x doesn't use any wars (it's not a servlet container).  However it does have an embedded HTTP server so what I'm looking for is the set of static HTML/CSS/JS/images files that I can put in my application.  We do this for other static web apps and works great.  I just need the static HTML/CSS/JS/images folder for hawtio.

hawtio.war comes with some backend Java servlets but if you really want only the static resources you can 'git clone' the hawtio/hawtio repos and run 'mvn clean install' to get them under hawtio-console-assembly/dist/

[David Hoffer]

Okay I will give that option a try...sounds like that is what I need.

Cool. This maven plugin config might give you insight on how to import them into your project:

We've never built Hawtio on Windows. This time I tried and see the same error, so it looks like yarn or the yarn maven plugin doesn't work well on Windows.

Alex, do you have any ideas?

[David Hoffer]

I wondered if it was a Linux build issue.  I can try to find a Linux box to build on...but I only have Windows.

-Dave

[Stan Lewis]

The main problem is the commands strung together with &&, that only works for bash.  When I used windows I'd use a cygwin bash shell to deal with this.  Or if you've windows 10 handy the Linux subsystem works really well.

Otherwise we could stand to make the build more windows friendly and replace the && with another approach in the package.json scripts, the goal is to just sequentially execute commands if they succeed and stop if one fails.

[David Hoffer]

I got the latest code and yes this part is building on Windows now...got a failure in hawtio-karaf but that doesn't concern me to much as the module I need built correctly.

However I was told the static resources would be in hawtio-console-assembly/dist/ and that doesn't look to be correct.  There is an index.html, login.html, etc but these just reference scripts in the lib and js folder in the head section, the body section just has an empty element so there is no displayable content here.

So I still don't know where to find the static resources that I would put in my vertx application.

The 'install-dependencies' in hawtio/hawtio-console-assembly/gulpfile.js was using the linux 'cp' command. I've replaced it with a gulp command, which is platform independent.

See if it solves the issue.

Fundamentally what we are trying to do is use Hawtio in a clustered Vertx server application.  Vertx is a reactive micro-service framework for the JVM.

We are using Hawtio for its metrics feature https://vertx.io/docs/vertx-dropwizard-metrics/java/

That link discusses using Hawtio in this section 'Using Jolokia and Hawtio' but it doesn't say how to host Hawtio so that is our problem.

For all of our other web apps in our vertx app we just use the builtin HTTP server for which Vertx uses Netty.  It's just a folder structure in a jar where the top level is referred to as the 'webroot', it loads the web app from that location.  Ideally we would like the same thing here, no wars, no embedded http server (we already have that), nothing but the web html, js, css, etc. (If there are additional jars for server side that is fine, we would just add to the classpath of the vertx module.)

The link you provided above doesn't seem to be what we are looking for as that requires including a war in our app which isn't really what we are looking for.

Hum...there doesn't seem to be a clean way to add this to a vert.x application.  If I use the  http://hawt.io/docs/get-started/#using-hawtio-embedded-in-a-java-application approach what port does the web UI run on?  Can I customize that?

OK, got it.

Hawtio is composed of a client-side and a server-side. The server-side includes some Java servlets and filters and works as a proxy to the Jolokia endpoint. You might be able to use just the client side but not without changes to your app.

The client app is in hawtio-console-assembly/dist/. After you run "yarn run build", you should have everything there.

This gulp task serves the client app for development:

https://github.com/hawtio/hawtio/blob/01068a1125d52d5559c73382186d2e85273a4075/hawtio-console-assembly/gulpfile.js#L187-L275

[abri...@redhat.com]

It might be simpler to expose a Jolokia endpoint in your vert.x application and remotely connect to it using the Hawtio standalone app.

[Tadayoshi Sato]

What kinds of static resources are you looking for?  Hawtio is essentially an anguarjs app so it's just composed of <body><hawtio-app></hawtio-app></body> and js/css libs.
