Re: [akka-user] akka-http is there an example of showing how to integrate with servlet container?

[Brian Maso]

Hi Feyyaz,

I'm thinking what you'd have to do to stay within your organization's
required JEE environment is to create a servlet that could feed messages to
a Source.actorRef or Source.queue. based on whether you could use the
servlet async API, or need to use the venerable synchronous servlet API, I
think you could get a successful integration with Akka Streams without
herculean effort.

It's no fun having to customize a framework the very first time you use it,
or to have to create "shims" like this. But I'm sure you'd find the effort
worth it. I have had a great amount of success using Akka Streams in
several different projects -- speeding up development, simplifying testing,
and getting reliable implementations as a result.

I'd be happy to help with pointers, advice, and hints.

Re: [akka-user] akka-http is there an example of showing how to integrate with servlet container?

[Feyyaz]

Hi,

I'm struggling the same issue as well. It's not a choice, but it's a 
requirement from the infrastructure team.

Unfortunately there is no way to directly bind it to a servlet. The easiest 
way is, as @√ says, to start/stop it with servlet, but it will run on a 
different port. For example, if your server runs on 8080, you can will 
Akka-HTTP from 8081.

You can use xsbt-web-plugin to create a servlet and package as a war file. 
(by following the instructions at 
https://github.com/earldouglas/xsbt-web-plugin).

After that, configure your web.xml to run your starter servlet on startup 
as below:


   
  Starter Servlet
  servlets.StarterServlet
  0
   
   
  Starter Servlet
  /*

Re: [akka-user] akka-http is there an example of showing how to integrate with servlet container?

[Ilya Cassina]

Hi √ and everyone,

It's 2017 and I'm still struggling with this (migrating from spray)…

Could somebody share the easy integration using ServletContextListener 
described above?

In particular I'm quite interested in
- how to use a generic servlet implementation backed up by a "routes: 
Route" created with akka-http.
- how to pass what once was "spray.boot-class" parameter to the servlet or 
the servlet initializer.

Thank you!

Ilya

One integration you can do easily is to have a ServletContextListener that
creates the Akka Http server endpoint when loaded and stops it on unload.
