jooby | The modular web framework for Java and Kotlin | Web Framework library

I've been struggling to understand how to package our app so we can run multiple commands in one Docker image.

Our set-up

bootstrap/Main is a picocli entrypoint which registers other commands, i.e. HttpServer, CliCommandOne, CliCommandTwo, etc. These commands can be defined in other modules/packages. The app is packaged as a JAR with Gradle application plugin. By default, without parameters, HttpServer command will be used. It is possible, because in HttpServer command we can start an HTTP server explicitly (we're using https://jooby.io/ framework now).

The Docker image is deployed to k8s. So we have a server running, and at the same time, we can exec into the container and run another CLI command.

The problem

We want to switch to another framework, e.g. Quarkus, Micronaut or Spring. And it looks like those frameworks either allow you to start an HTTP server (or WebSocket) or create a CLI command, but there is no way to replicate what we have now, i.e. package multiple commands in one JAR and be able to start them in one Docker image.

Solutions we thought of

What I can think of is an approach that Kafka is using: they have one JAR, as far as I understand, and then use a lot of sh scripts (https://github.com/apache/kafka/tree/trunk/bin) to run different classes https://github.com/apache/kafka/blob/trunk/bin/kafka-run-class.sh. This seems like too customized for us.

We can, of course, generate separate JARs for every class with main method, and then create different Docker images and somehow find a way to run them. But that seems like an overhead in terms of Docker images. What if we need 20 commands?

So I'm looking for a way how to we package the app in order to have multiple executable "commands". I'm not even sure, if it's a good idea. Would be glad to hear about possible options or best practices.

I am trying to attach the remote server to 8000 in intellij.

Also started the server in debugging mode using the command mvn jooby:run -Dapplication.fork=true

But, I am getting connection failed exception.

I have developed a Jooby-Application which is hosted on a netty server. I can access the application on localhost and tests were fine. Now I want to make the app accessable over internet and dont know what is the best way to reach this goal?

The complete application is hosted on a Windows Server, because it uses Excel. (Read/Write over Apache POI. For macros it has to be Windows) Should I try to connect the running netty-server with IIS or can I just forward the requests from outside to localhost? The last mentioned approach propably is a bad idea regarding security issues.

I am currently experimenting with writing webapps/apis using Jooby. I have it set up with an endpoint that returns account data, either as HTML or as JSON depending on the accept header value. This endpoint works and returns the correct information.

When writing unit tests in JUnit, how do I pass an accept header value along with my get request so that I can test what is returned from the request properly?

I have tried using Mockito to mock a Request object and return responses to various calls to the request object but I can't seem to find in the documentation how Jooby tests for the header values within it's own Request object when you use the Results.when method.

This is my endpoint:

I'm setting up a simple Jooby Webserver. I have a App.java and a home.html file. For now, the only thing i want it to do, is that if you open the home page it shows a html page saying "Hello World". However, I'm always getting the error "org.jooby.Err: Not Acceptable(406): text/html".

I created the project via maven with an archetype, but I also tried to create it with gradle. I run the program with Java 8, in IntellIJ IDEA. I've already tried using different HTML files, but I don't think anything is wrong with it, because if I return it as a raw String, it works (I just don't want to do it because I would't be able to use JavaScript and Image files normally). I've also tried doing it in a seperate class, doing it with the get() method, and I tried to not return the Result but instead do response.send(result).

Here is my code:

I've got pretty simple application that uses Jooby as web framework. Its class responsible for REST looks like this

I am creating an API with the Jooby framework mostly following this guide. I am also using Vue.js as the frontend. However I am having issues with CORS. When I try to do a get request from my Vue.js frontend I get the error No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8081' is therefore not allowed access.

This is my Jooby application.conf file:

I have the following problem:

I have a rest API on a jooby server. I want to create a custom annotation interceptor which handles particular requests and validates the oauth token in the header.

How do you put multiple method calls (e.g 'get' in the below case) in a block?
