i think that would be a very long list now (but no, i don't know of one)

We use it at Microsoft.

Has anyone ever had this issue when running

./gradlew run

? (Kotlin + JVM 1.8)

Tables.java:12: error: package javax.annotation is not visible
import javax.annotation.Generated;
            ^
  (package javax.annotation is declared in module java.xml.ws.annotation, which is not in the module graph)

which web framework do you recommend?

A bit like the last question here: I'm looking into technologies and frameworks for creating web services that also provide a content management system. We've been using Drupal (php) for this at our office most of the time, but it feels like the framework is blocking us too much. After looking into Symfony CMF (also php), I wonder if there are any good JVM solutions for this? I used Spring Boot and Ktor but I wonder if you know a recommended solution for a CMS that can be coupled with these?

Any recommendations how to integrate

kotlin-logging

with

ktor

? 😮

Hey guys. I have an issue with Kotlin and Spring. Kotlin NoArg plug-in is not creating default constructor. I already asked on SO https://stackoverflow.com/questions/51352067/noarg-constructor-is-not-getting-created

Anyone know of a simple jsonrpc library for Kotlin?

Is there a way to specify inline styles in kotlinx.html? Exploring the API hasn't uncovered it yet if it's there

Hi, I'm new to Kotlin. I have a Spring Boot application currently written in Java, We are writing new APIS's in Kotlin. I have a question regarding handling

Entity to DTO conversion

. I created a

data class

for the

entity

and added a

toDto

method on it. But here the

Entity

is aware of the DTO, which isn't really required for the entity. It works fine. But I am not sure if this is the right way of doing it? Any thoughts? 🙏 A simpler version of my code is:

//Person DTO

data class PersonDto (
	val name: String
)

//Person Entity

@Entity
@Table(name = "persons")
data class Person(
@Id
val id: Integer,

@Column
val firstName: String,

@Column
val lastName: String
)

{
    internal fun toDto(): PersonDto = PersonDto(
            name = "${this.firstName}  ${this.lastName}"
    )

}

Hi @Gokul - I would use an Extension on the Entity object to convert to DTO ....

fun Person.toDto() = PersonDto("${firstName}  ${lastName}")

. You can then call person.toDto(). The Extension function lives outside the Person class (say, in Extensions.kt) in the same package as the DTO class.

Hi, im android developer. I want to ask, whats the current go to framework for medium sized webserver?

I'd rather inject it though

Hello. I'm working on a pure kotlin-based web projetc. It's work fine locally and i want to deploy it on a cloud foundry. But the official Java buildpack does not work for it. Any idea on how i can make this works ? ( I created a channel for it #cloudfoundry)

My current project is now completely non-blocking behind coroutines EXCEPT for JDBC connecting to MySQL 😢

async jdbc specs are underway

We are building async client libraries based on kotlinx.io, @Deactivated User’s extensive work on various clients (https://github.com/soywiz/ktor-cio-clients) and coroutines. It’s not there yet, but we have some Redis client sources here https://github.com/ktorio/ktor-client-redis Next coming is PostgreSQL, then MySQL and such. We are planning to integrate this work into #squash as an experiment and then see how it works.

hopefully it's not too spammy to say that javalin 2.0 is out here: https://javalin.io/news/javalin-2.0.0-stable.html

I am thinking about porting this mysql/postgres async driver to kotlin: https://github.com/mauricio/postgresql-async Is anyone interested using it? want to assist with the task? please ping me directly

Quick tip for you guys: When using coroutines in a Spring

@Component

always make sure that the class implements some interface. The Spring CGLib Enhancer messes stuff up and causes hard to find `NullPointerException`s.

listview(controller.configSections) {
                cellFragment(ConfigSectionFragment::class)
                //This should bind that item
                model.itemSelected.bind(selectionModel.selectedItemProperty().isNotNull)
                model.selectedConfigSection.bind(selectionModel.selectedItemProperty())
            }

works, but using

bindSelected(model.selectedConfigSection)

does not

How can we improve that? is the website on github?

What if I know for sure that the variable can't be nullable at a given point

I mean, should I only use !! if dealing with legacy code?

Hi everyone! This is not a proper Kotlin question, but a server one. I'm using Vertx and its http server to serve to client a buffer of bytes from a server folder. When this buffer is an MP4 video it breaks on Safari, but actually works on Chrome and Firefox. Safari says error using plugin. I read on web that could be a header problem. As headers I serve - content-type: video/mp4 - content-length: <length of video> Response code served to client: 200 Have you ever experienced something like that?

Hi All ,I just started my career as backend engineer, what all things should I learn and where can I find best advance java documentation/ course. Also I believe in learning through application and project. where can I search for open source projects to which I can contribute and learn.🙂 Thanks

Hi All, I am are currently rewriting a legacy system with Kotlin, Spring boot and JPA and so I have three modules of which two are services and a shared module which includes entities, Utils and repositories etc. Now on the dependent projects main I have used annotations @ComponentScan(value = ["com.bla.mypackage"]) and @EnableJpaRepositories and I can run the services and beans are autowired but when I run tests I get Unsatisfied dependency exception and my testBase is annotated with Test and @ContextConfiguration(classes = [MyService::class]). What could I be missing?
