Classes in jakarta.portlet used by jakarta.portlet

Class	Description
ActionParameters	Action parameters are additional portlet parameters added to the portlet URL or provided by the client that extend the state information provided by the render parameters.
ActionRequest	The ActionRequest represents the request sent to the portlet to handle an action. It extends the ClientDataRequest interface and provides action request information to portlets.
ActionResponse	The ActionResponse interface represents the portlet response to an action request.
ActionURL	An action URL is created with MimeResponse.createActionURL().

HeaderRequest	Tag interface designating a header request object.
HeaderResponse	The portlet programming interface provides a mechanism to assist portlets when the aggregated portal markup is an HTML or similar document that requires markup for the document HEAD section to be written and HTTP headers to be set before the render markup for each individual portlet is aggregated.

MimeResponse.Copy	Specifies processing when a URL is created.

PortletAsyncContext	Class representing the execution context for an asynchronous operation that was initiated on a ResourceRequest.
PortletAsyncEvent	Event that gets fired when the asynchronous operation initiated on a ResourceRequest (via a call to ResourceRequest#startAsync or ResourceRequest#startAsync(ResourceRequest, ResouceResponse)) has completed, timed out, or produced an error.
PortletAsyncListener	Listener that will be notified in the event that an asynchronous operation initiated on a ResourceRequest to which the listener had been added has completed, timed out, or resulted in an error.
PortletConfig	The PortletConfig interface provides the portlet with its configuration.
PortletContext	The PortletContext interface defines a portlet view of the portlet container.

PortletMode	The PortletMode class represents the possible modes that a portlet can assume.
PortletModeException	The PortletModeException is thrown when a portlet tries to use or set a portlet mode that is not supported by the current runtime environment or the portlet.
PortletParameters	The PortletParameters interface defines the API for accessing the parameters that are set for the portlet or on a portlet URL.
PortletPreferences	The PortletPreferences interface allows the portlet to store configuration data.
PortletRequest	The PortletRequest defines the base interface to provide client request information to a portlet.
PortletRequest.P3PUserInfos	P3P user information constants.
PortletRequestDispatcher	The PortletRequestDispatcher interface defines an object that receives requests from the client and sends them to the specified resources (such as a servlet, HTML file, or JSP file) on the server.
PortletResponse	The PortletResponse defines the base interface to assist a portlet in creating and sending a response to the client.
PortletSecurityException	A portlet should throw a PortletSecurityException when a call fails because of security reasons. Additionally it can be thrown by the portal/portlet-container.
PortletSession	The PortletSession interface provides a way to identify a user across more than one request and to store transient information about that user.
PortletURL	The PortletURL interface represents a URL that reference the portlet itself.
ReadOnlyException	The ReadOnlyException is thrown when a portlet tries to change the value for a read-only preference attribute.
RenderParameters	Provides access to render parameters, which make up part of the render state.
RenderRequest	The RenderRequest represents the request sent to the portlet to handle a render.
RenderResponse	The RenderResponse defines an object to assist a portlet in sending a response to the portal.
RenderState	Provides read-only access to the render state.
RenderURL	This is a marker interface for a render URL.
ResourceParameters	Resource parameters are additional portlet parameters added to the URL that extend the state information provided by the render parameters.
ResourceRequest	The ResourceRequest interface represents the request send to the portlet for rendering resources.
ResourceResponse	The ResourceResponse defines an object to assist a portlet for rendering a resource.
ResourceServingPortlet	The ResourceServingPortlet interface allows serving resources through the portlet.
ResourceURL	The ResourceURL defines a resource URL that when clicked will result in a serveResource call of the ResourceServingPortlet interface.
StateAwareResponse	The StateAwareResponse represents a response that can modify render state information or send events.
ValidatorException	The ValidatorException is thrown by the validate method of a PreferencesValidator when the validation of a preference failed.
WindowState	The WindowState class represents the possible window states that a portlet window can assume.
WindowStateException	The WindowStateException is thrown when a portlet tries to use a window state that is not supported by the current runtime environment or the portlet.
