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