The PortletException class defines a general exception that a portlet can throw when it is unable to perform its operation successfully.
The PortletMode class represents the possible modes that a portlet can assume.
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.
The PortletPreferences interface allows the portlet to store configuration data.
The PortletRequest defines the base interface to provide client request information to a portlet.
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.
The PortletResponse defines the base interface to assist a portlet in creating and sending a response to the client.
A portlet should throw a PortletSecurityException when a call fails because of security reasons.
Additionally it can be thrown by the portal/portlet-container.
The PortletSession interface provides a way to identify a user across more than one request and to store transient information about that user.

The RenderResponse defines an object to assist a portlet in sending a response to the portal.
The portlet should throw the UnavailableException when the portlet is either temporarily or permanently unavailable to handle requests.
The UnmodifiableException is thrown when a portlet tries to change the value for a preference attribute, marked as unmodifiable in the deployment descriptor with the non-modifiable tag, without the needed permissions.
The ValidatorException is thrown by the validate method of a PreferencesValidator when the validation of a preference failed.
The WindowState class represents the possible window states that a portlet window can assume.
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.
