Question

Please can someone with JAX RS and Kotlin have a look at this question <https stackoverflow com q 54674096 9506917>

Shawn · Answer

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

Shawn · Answer

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 · Answer

oh wait I misread what you wrote

Shawn · Answer

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 · Answer

okay

Hexa · Answer

ohh

Hexa · Answer

so i may have to use jacksonmapper

Shawn · Answer

or something similar yes

Shawn · Answer

what s the stack trace on the server side look like

Hexa · Answer

there s no stack trace as I can t run it in debug mode

Hexa · Answer

it just says ``` gt 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 Press any key to shutdown lt ========== gt 80 EXECUTING 27s gt run ```

Shawn · Answer

Well there should still be something in the logs I think

Shawn · Answer

also why can t you run it in debug mode

Shawn · Answer

weird

Hexa · Answer

when I call the GET

Hexa · Answer

i get this

Hexa · Answer

```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 gt GET <http localhost 8080 myresource test123> 2 gt accept 2 gt host localhost 8080 2 gt 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 lt 200 2 lt Content Type application json hello ```

Hexa · Answer

so it seems like POST does not even reach my server

Shawn · Answer

No this seems like a failure of the logging configuration

Shawn · Answer

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

Shawn · Answer

It doesn t seem useful to you to suppress stack traces

Hexa · Answer

wait a sec

Hexa · Answer

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

Hexa · Answer

``` message foo ```

Shawn · Answer

that is what most folks do yes

Hexa · Answer

would `Message message String ` do

Shawn · Answer

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

tddmonkey · Answer

while you re testing just accept a `Map lt Any Any gt `

tddmonkey · Answer

Jackson also has a `KotlinModule` you will need to register

tddmonkey · Answer

It s in `jackson module kotlin`

Hexa · Answer

did you mean change my function to `fun createMessage testPost Map lt Any Any gt `

Hexa · Answer

that didnt worked

Hexa · Answer

just tried it

Hexa · Answer

let me try jacksonmapper

Joe · Answer

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 · Answer

not working still even with Plain text

Hexa · Answer

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 · Answer

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 · Answer

it just seems like its not reaching my server at all

Hexa · Answer

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 · Answer

decided to moved to spring in the end much easier

Shawn · Answer

shrug

Shawn · Answer

fwiw I ve been pretty happy using Dropwizard and Kotlin together

Joe · Answer

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

tddmonkey · Answer

Yeah we use DW + kotlin extensively
