[jboss-jira] [JBoss JIRA] (WFLY-6097) Error response handling from bean validation ignores Accept header

[Gunnar Morling (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-6097?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13158673#comment-13158673 ] 

Gunnar Morling commented on WFLY-6097:
--------------------------------------

Can you attach the sources of a simple example (e.g. without database interactions) and your invocation of the REST endpoint, please? Maybe you are not specifying the accept header correctly.

It works as expected for me, when specifying the request header "Accept: application/json", I'll get back a JSON response, otherwise the plain text representation (the -1 in the payload is violating a constraint of my example service):

{code}
curl -XPOST <MY_URL> -H "Content-Type: application/json" -H "Accept: application/json" -d '-1'
{code}

{code}
{"exception":null,"fieldViolations":[],"propertyViolations":[],"classViolations":[],"parameterViolations":[{"constraintType":"PARAMETER","path":"test.arg0","message":"must be greater than or equal to 1","value":"-1"}],"returnValueViolations":[]}%
{code}

> Basically I have a very simple application that has request validation in the REST endpoints.
> According to the documentation of RESTEasy, I should get a JSON error response if I put "application/json" in Accept header in the request.
> https://docs.jboss.org/resteasy/docs/3.0.13.Final/userguide/html/Validation.html#d4e2472
> The mentioned feature worked just fine in Wildfly 9.0.2.Final. Now, however, it doesn't.
> I have tried to upgrade the dependencies in the pom.xml to use dependencies from Wildfly 10.0.0.Final, but still no luck. Though the attached application deploys just fine in Wildfly 9.0.2.Final and Wildfly 10.0.0.Final.
> In WF 9.0.2.Final I used to get the below error *JSON*
> {code:json}
> {
> 	"exception": null,
> 	"fieldViolations": [],
> 	"propertyViolations": [],
> 	"classViolations": [],
> 	"parameterViolations": [{
> 		"constraintType": "PARAMETER",
> 		"path": "registerLogisticsNetwork.arg0.name",
> 		"message": "may not be null",
> 		"value": ""
> 	}],
> 	"returnValueViolations": []
> }
> {code}
> In WF 10.0.0.Final I get this:
> {code}
> [PARAMETER]
> [registerLogisticsNetwork.arg0.name]
> [may not be null]
> []
> {code}
