I had similar problem while using in postman  for POST request under header section add these as   key valuepair  Content-Type application json Accept application json  i hope it will work

User · Answer

just change the content-type to application json when you use JSON with POST PUT  etc

User · Answer

If none of the solution worked and you are working with JAXB  then you need to annotate your class with  XmlRootElement  to avoid 415 unsupported media type

I get the same issue  In fact  the request didn t reach the jersey annoted method  I solved the problem with add the annotation   Consumes MediaType APPLICATION FORM URLENCODED  The annotation  Consumes      don t work        Path     PropertiesHabilitation KEY EstNouvelleGH       POST        Consumes             Consumes MediaType APPLICATION FORM URLENCODED      public void  get  EstNouvelleGH   Context HttpServletResponse response

Just in case this is helpful to others  here s my anecdote   I found this thread as a result of a problem I encountered while I was using Postman to send test data to my RESTEasy server  where- after a significant code change- I was getting nothing but 415 Unsupported Media Type errors   Long story short  I tore everything out  eventually I tried to run the trivial file upload example I knew worked  it didn t   That s when I realized that the problem was with my Postman request   I normally don t send any special headers  but in a previous test I had added a  Content-Type    application json  header   OF COURSE  I was trying to upload  multipart form-data   Removing it solved my issue   Moral  Check your headers before you blow up your world

Don t return Strings in your methods but Customer objects it self and let JAXB take care of the de serialization

User · Answer

The issue is in the deserialization of the bean Customer  Your programs knows how to do it in XML  with JAXB as Daniel is writing  but most likely doesn t know how to do it in JSON   Here you have an example with Resteasy Jackson http   www mkyong com webservices jax-rs integrate-jackson-with-resteasy   The same with Jersey  http   www mkyong com webservices jax-rs json-example-with-jersey-jackson

I had this issue and found that the problem was that I had not registered the JacksonFeature class      Create JAX-RS application  final Application application   new ResourceConfig                register JacksonFeature class     Without doing this your application does not know how to convert the JSON to a java object    https   jersey java net documentation latest media html json jackson

I encountered the same issue in postman  i was selecting Accept in header section and providing the value as  application json   So i unchecked and selected Content-Type and provided the value as  application json   That worked

User · Answer

I had the same issue  as it was giving error-415-unsupported-media-type while hitting post call using json while i already had the    Consumes MediaType APPLICATION JSON     and request headers as in my restful web service using Jersey 2 0   Accept application json Content-Type application json   I resolved this issue by adding following dependencies to my project   lt dependency gt   lt groupId gt org glassfish jersey media lt  groupId gt   lt artifactId gt jersey-media-json-jackson lt  artifactId gt   lt version gt 2 25 lt  version gt   lt  dependency gt    this will add following jars to your library     jersey-media-json-jackson-2 25 jar jersey-entity-filtering-2 25 jar jackson-module-jaxb-annotations-2 8 4 jar jackson-jaxrs-json-provider-2 8 4 jar jackson-jaxrs-base-2 8 4 jar   I hope it will works for others too as it did for me

Add Content-Type  application json and Accept  application json in REST Client header section

User · Answer

In case you are trying to use ARC app from google and post a XML and you are getting this error  then try changing the body content type to application xml  Example here
