javax.ws.rs.BadRequestException：HTTP 400错误请求

Question

我有一个JAX RS Rest服务，其请求类如下

@XmlRootElement(name = "CDSRequest")
@XmlSeeAlso({MyClass.class})
@XmlType(name = "CDSRequest", propOrder = {"data", "refClass"})
public class CDSRequest {
    Object data;
    Class  refClass;

    public Class getRefClass() {
        return refClass;
    }

    public void setRefClass(Class refClass) {
        this.refClass = refClass;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }
}

当我使用上面的请求对象进行REST调用时，我得到以下错误。我怀疑数据的通用对象类型的问题。但我认为**@XmlSeeAlso**会解决它。请帮忙
