43   * This class provides a HTTP utility for the <code>com.liferay.portlet.workflow.service.WorkflowInstanceServiceUtil</code>
44   * service utility. The static methods of this class calls the same methods of the
45   * service utility. However, the signatures are different because it requires an
46   * additional <code>com.liferay.portal.security.auth.HttpPrincipal</code> parameter.
47   * </p>
48   *
49   * <p>
50   * The benefits of using the HTTP utility is that it is fast and allows for tunneling
51   * without the cost of serializing to text. The drawback is that it only works with
52   * Java.
53   * </p>
54   *
55   * <p>
56   * Set the property <code>tunnel.servlet.hosts.allowed</code> in portal.properties
57   * to configure security.
58   * </p>
59   *
60   * <p>
61   * The HTTP utility is only generated for remote services.
