I have a jax-rs web service like:

@GET
@Path("/getAnalyzedMatches")
@Produces(MediaType.APPLICATION_XML)
public static AnalyzeResponseModel getAnalyzedMatches() throws ClassNotFoundException, SQLException {
    AnalyzeResponseModel response = new AnalyzeResponseModel();
    List<AnalyseResultModel> analyzedMatches = SoveMatchesUtil.getAnalyzedMatches();
    /* try to set object */
    List<Object> objectList = new ArrayList<>();
    for (AnalyseResultModel item : analyzedMatches) {
        objectList.add(item);
    }
    response.setList(objectList);
    return response;
}

Here is my Response Model:

package com.sove.model;

import java.util.List;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "list")
public class AnalyzeResponseModel {
    List<Object> list;

    public AnalyzeResponseModel() {
    }

    public List<Object> getList() {
        return list;
    }

    @XmlAttribute
    public void setList(List<Object> list) {
        this.list = list;
    }

}

Here is my pom.xml:
