Answer 1

The message body writer exception listed by the OP will be raised if you don't annotate your POJO (or base POJO) with @XmlRootElement.

For example:

@XmlRootElement
public class BaseBean
{
    private Boolean success = Boolean.TRUE;
    private String message;

    /**
     * Empty constructor to satisfy requirements of JAXRS.
     */
    public BaseBean() {}

    /**
     * Returns a simple message to accompany the success/failure.
     * @return
     */
    public String getMessage()
    {
        return message;
    }

    /**
     * Sets the message (if required).
     * @param message
     */
    public void setMessage(String message)
    {
        this.message = message;
    }

    /**
     * Returns a flag indicating whether a request for content was
     * successful.
     * @return
     */
    public Boolean getSuccess()
    {
        return success;
    }

    /**
     * Marks the success of a request for content.
     * @param success
     */
    public void setSuccess(Boolean success)
    {
        this.success = success;
    }
}
