rest - java client consuming API -

i trying use mail gun api getting bounce mail data.

public static clientresponse getbounce() {       client client = new client();            client.addfilter(new httpbasicauthfilter("api",                            "key-xxxxxxxxxxxxxxxxxxxxx"));            webresource webresource =                    client.resource("https://api.mailgun.net/v3/xxxxxxxxxxxx.mailgun.org/" +                                    "bounces/foo@bar.com");     return webresource.get(clientresponse.class);} 

it works fine api call ok not able convert clientresponse in appropriate type in cae emailerror . actual response server {"address":"a@gmail.com","code":"550","error":"550 5.2.1 email account tried reach disabled. lq5si9613879igb.63 - gsmtp","created_at":"tue, 18 aug 2015 12:23:35 utc"}

i created pojo map response

@jsonautodetect(gettervisibility = visibility.none, fieldvisibility = visibility.any) @jsonserialize(include = inclusion.non_null) public class emailerror {     private string address;     private string error;     private string created_at; //geters... //setters.. } 

and try map clientresponse emailerror type.

clientresponse clientresponse = getbounce(email);          emailerror error = response.getentity(new generictype<emailerror>() {          }); 

where clientresponse object return method getbounce()

it throws exception com.sun.jersey.api.client.clienthandlerexception: message body reader java class com.che.rt.businessservices.emailerror, , java type class com.che.rt.businessservices.emailerror, , mime media type application/json;charset=utf-8 not found 

any guess missing.

you seem have jackson dependency (as you're using annotations) not enough jersey. jersey uses messagebodyreaders deserialize request/response bodies. need 1 can handle json. jackson implements jax-rs reader , writer. dependency need jackson provider, not primary jackson libraries.

for jersey can add dependency

<dependency>     <groupid>com.sun.jersey</groupid>     <artifactid>jersey-json</artifactid>     <version>1.19</version> </dependency> 

this pull in jackson 1.9.2, can rid of other jackson dependencies have, version don't conflict. need register jackson provider jersey client. can do

clientconfig config = new defaultclientconfig(); config.getproperties().put(jsonconfiguration.feature_pojo_mapping, true); config.getsingletons().add(new jacksonjsonprovider()); client client = client.create(config); 

note above uses jackson 1.9.2. if want use newer 2.x jackson, instead of above dependency, use one

<dependency>     <groupid>com.fasterxml.jackson.jaxrs</groupid>     <artifactid>jackson-jaxrs-json-provider</artifactid>     <!-- or whatever [2.2,) version want use -->     <version>2.5.0</version> </dependency> 

then configuration should different

clientconfig config = new defaultclientconfig(); config.getsingletons().add(new jacksonjsonprovider()); client client = client.create(config);
