Jersey not mapping response to JAVA Object

Question

I am trying to consume Google Time Zone API Response. I have tried all answers on Stack Overflow related to this error but the below error is not even changing a bit:

ERROR [ClientResponse]:625 - A message body reader for Java class com.bystored.business.bo.timezone.TimeZoneResponse, and Java type class com.bystored.business.bo.timezone.TimeZoneResponse, and MIME media type application/json; charset=UTF-8 was not found

Below is my JAVA class:

public class TimeZoneResponse implements Serializable {
private long dstOffset;
private long rawOffset;
private String status;
private String timeZoneId;
private String timeZoneName;

@JsonProperty("dstOffset")
public long getDstOffset() {
    return dstOffset;
}

public void setDstOffset(long dstOffset) {
    this.dstOffset = dstOffset;
}

@JsonProperty("rawOffset")
public long getRawOffset() {
    return rawOffset;
}

public void setRawOffset(long rawOffset) {
    this.rawOffset = rawOffset;
}

@JsonProperty("status")
public String getStatus() {
    return status;
}

public void setStatus(String status) {
    this.status = status;
}

@JsonProperty("timeZoneId")
public String getTimeZoneId() {
    return timeZoneId;
}

public void setTimeZoneId(String timeZoneId) {
    this.timeZoneId = timeZoneId;
}

@JsonProperty("timeZoneName")
public String getTimeZoneName() {
    return timeZoneName;
}

public void setTimeZoneName(String timeZoneName) {
    this.timeZoneName = timeZoneName;
}

@Override
public String toString() {
    return "TimeZoneResponse{" +
            "dstOffset=" + dstOffset +
            ", rawOffset=" + rawOffset +
            ", status='" + status + '\'' +
            ", timeZoneId='" + timeZoneId + '\'' +
            ", timeZoneName='" + timeZoneName + '\'' +
            '}';
}
}

Jersey Client GET method is below:

public static <T extends Object> T get (String url, Map<String, String> queryParams, Map<String, String> headers, Class<? extends T> type) {
    Client client = Client.create();
    WebResource webResource = client.resource(url);

    if (queryParams != null) {
        for (String key : queryParams.keySet()) {
            webResource = webResource.queryParam(key, queryParams.get(key));
        }
    }

    WebResource.Builder builder = webResource.getRequestBuilder();
    if(headers != null && !headers.isEmpty()) {
        for(Map.Entry<String, String> entry : headers.entrySet()) {
            builder = webResource.header(entry.getKey(), entry.getValue());
        }
    }

    return builder.accept(MediaType.APPLICATION_JSON).get(type);

}

I have dependencies of jersey-server jersey-bundle jersey-json in pom .

Answer 1

Just like you configure the POJOMappingFeature on the server, you need to also configure it on the client

ClientConfig config = new DefaultClientConfig();
config.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
Client client = Client.create(config);

It's been a while since I used Jersey 1, so if the above doesn't work, then use config.getProperties() , but I think it should be getFeatures .
