Please can someone with JAX-RS and Kotlin have a look at this question: https://stackoverflow.com/q/54674096/9506917

first thing that comes to mind, maybe try adding a leading slash to your @Path argument on the get endpoint?

[Shawn]

also I’d annotate the class itself with `@Produces(MediaType.APPLICATION_JSON)`if all your endpoints return JSON, but that’s a side observation not related to your path problems

[Shawn]

oh, wait, I misread what you wrote

[Shawn]

your POST endpoint is likely being called but 500ing because you probably don’t have anything set up to deserialize the json blob to String

[Hexa]

okay

[Hexa]

ohh

[Hexa]

so i may have to use jacksonmapper??

[Shawn]

or something similar, yes

[Shawn]

what’s the stack trace on the server side look like?

[Hexa]

there's no stack trace as I can't run it in debug mode

[Hexa]

it just says

> Task :run 
Feb 13, 2019 4:02:25 PM org.glassfish.grizzly.http.server.NetworkListener start
INFO: Started listener bound to [0.0.0.0:8080]
Feb 13, 2019 4:02:25 PM org.glassfish.grizzly.http.server.HttpServer start
INFO: [HttpServer] Started.

[Shawn]

Well, there should still be something in the logs, I think

[Shawn]

also why can’t you run it in debug mode?

[Shawn]

weird

[Hexa]

when I call the GET

[Hexa]

i get this

[Hexa]

Feb 13, 2019 4:03:16 PM org.glassfish.jersey.logging.LoggingInterceptor log
INFO: 2 * Server has received a request on thread grizzly-http-server-1
2 > GET <http://localhost:8080/myresource/test123>
2 > accept: */*
2 > host: localhost:8080
2 > user-agent: curl/7.54.0

Feb 13, 2019 4:03:16 PM org.glassfish.jersey.logging.LoggingInterceptor log
INFO: 2 * Server responded with a response on thread grizzly-http-server-1
2 < 200
2 < Content-Type: application/json
hello

[Hexa]

so it seems like POST does not even reach my server???

[Shawn]

No, this seems like a failure of the logging configuration.

[Shawn]

do you have logback or anything configured? or maybe you could run your application without using gradle?

[Shawn]

It doesn’t seem useful to you to suppress stack traces

[Hexa]

wait a sec

[Hexa]

maybe i need to create a data class to represent this json?

[Hexa]

{"message": "foo"}'

[Shawn]

that is what most folks do, yes

[Hexa]

would Message(message: String) do??

[Shawn]

if you’re using Jackson, the kotlin mapper can automagically deserialize data classes for you

[tddmonkey]

while you’re testing, just accept a Map<Any, Any>

[tddmonkey]

Jackson also has a KotlinModule you will need to register

[tddmonkey]

It’s in jackson-module-kotlin

[Hexa]

did you mean change my function to fun createMessage(testPost: Map<Any, Any>)?

[Hexa]

that didnt worked

[Hexa]

just tried it

[Hexa]

let me try jacksonmapper

[Joe]

also you seem to be accepting/producing raw strings right now, does it work with MediaType.PLAIN_TEXT? -- jersey doesn't particularly support raw strings as json, so either label strings as plain text or return json-able entity classes is best

[Hexa]

not working still, even with Plain text

[Hexa]

I was just following this exact same repo and changed just this class: https://github.com/baens/blog-step-by-step-jaxrs/blob/master/src/jaxrs/resources/HelloWorld.kt

[Hexa]

problem still the same even after i simplified my POST function to this @Joe

@POST
    @Consumes(MediaType.TEXT_PLAIN)
    @Produces(MediaType.TEXT_PLAIN)
    fun createMessage(message: String): Response {
        return Response.status(200).entity("test").build()
    }

[Hexa]

it just seems like its not reaching my server at all

[Hexa]

okay I got a 200 after sending a POST with no data like this

curl -v -X POST \
  <http://localhost:8080/messages> \
  -H 'Content-Type: application/json'

[Hexa]

decided to moved to spring in the end. much easier

[Shawn]

shrug

[Shawn]

fwiw I’ve been pretty happy using Dropwizard and Kotlin together

[Joe]

yeah, i keep meaning to look @ ktor, but having much success w/ dropwizard already

[tddmonkey]

Yeah, we use DW + kotlin extensively
