How can we create Jaxb or Jackson objects from wsdl?

Is there a way to create Jaxb/Jackson objects like shown below (https://github.com/jesperfj/force-rest-api)

import org.codehaus.jackson.annotate.JsonIgnoreProperties;
import org.codehaus.jackson.annotate.JsonProperty;

@JsonIgnoreProperties(ignoreUnknown=true)
public class Account {

@JsonProperty(value="Id")
String id;
@JsonProperty(value="Name")
String name;
@JsonProperty(value="AnnualRevenue")
private Double annualRevenue;
@JsonProperty(value="externalId__c")
String externalId;

public String getId() { return id; }
public void setId(String id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public Double getAnnualRevenue() { return annualRevenue; }
public void setAnnualRevenue(Double value) { annualRevenue = value; }
public String getExternalId() { return externalId; }
public void setExternalId(String externalId) { this.externalId = externalId; }
}
