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